A - 2
[Design Precautions]
DANGER ● Configure safety circuits external to the conversion unit to ensure that the entire system operates safely even
when a fault occurs in the external power supply or the conversion unit. Failure to do so may result in an
accident due to a malfunction or incorrect output.
(1) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and protective
interlock circuit for forward/reverse operation or upper/lower limit positioning.
(2) When the conversion unit detects an error such as a watchdog timer error by the self-diagnostic function,
all outputs are turned off. Also, output controls may not work when an error occurs in a part, such as I/O
control part, where the conversion unit cannot detect any error. To ensure safety operation in such a
case, provide a safety mechanism or external circuit.
(3) Outputs may remain on or off due to a failure of an output module relay, transistor, or triac. To ensure
safety operation, configure an external circuit to monitor output signals that could cause a serious
accident.
CAUTION ● Noise interference can cause erroneous data to be written to the conversion unit, resulting in an incorrect
operation of the conversion unit which may cause an accident, or damage the machine. Always ensure the
following items are observed.
(1) Do not bundle main circuit lines or high-voltage lines with load lines.
Do not keep these lines close to each other as they are easily affected by noise and surge induction.
When wiring, keep the above lines at least 100 mm apart.
(2) The shield of shielded cords and shielded cables must be grounded to a point on the programmable
controller side. However, do not use a common ground with strong electrical equipment.
(3) Input, power supply, and optical fiber connectors should be used without any force applied on them.
Excessive force will cause cables to disconnect and fail.
● Provide appropriate circuits external to the conversion unit to prevent cases where danger may result from
abnormal operation of the overall system in the event of an external power supply fault or conversion unit
failure.
● If a fault occurs in the conversion unit or servo amplifier, shut off the power at the control power source of the
servo amplifier.
● Do not apply a voltage other than that specified in the instruction manual on any terminal. Doing so may
cause destruction or damage.
● Do not reverse the polarity (+ / -). Doing so can cause an explosion or damage.
A - 3
[Installation Precautions]
DANGER ● Shut off the external power supply (all phases) used in the system before mounting or removing the
conversion unit. Not doing so could result in an electric shock or damage to the unit.
CAUTION ● Never try to disassemble or modify the conversion unit. It may cause a product failure, operation failure,
injury, or fire.
● Do not drop or apply strong impact on the conversion unit. Doing so will damage the unit.
● Use the conversion unit in an environment that meets the general specifications contained in this manual.
Using the conversion unit in an environment outside the range of the general specifications could result in an
electric shock, fire, operation failure, and damage to or deterioration of the unit.
● When using the conversion unit in places subject to vibration, fix the unit with screws. Tighten the screws
within the specified torque range. Undertightening may cause a drop, short circuit or malfunction.
Overtightening may cause a drop, short circuit, or malfunction due to damage to the screws or conversion
unit.
● Do not directly touch the conductive parts and electronic components of the conversion unit. Doing so may
cause malfunction or failure of the unit.
● Lock the control panel and prevent access to those who are not certified to handle or install electric
equipment.
● Mount the conversion unit, servo amplifier, servo motor, and regenerative resistor on incombustible material.
Mounting them directly or close to combustibles will lead to fire.
[Wiring Precautions]
DANGER ● Shut off the external power supply (all phases) used in the system before installation or wiring.
Not doing so could result in an electric shock or damage to the product.
CAUTION ● Be sure to ground the earth terminal FG and LG. (Ground resistance: 100 or less)
Not doing so could result in an electric shock or malfunction.
● Check the product's rated voltage and the terminal layout. Make sure to wire the conversion unit correctly.
Connecting a power supply that differs from the rating or incorrectly wiring the product could result in fire or
failure.
● External connections shall be crimped or pressure welded with the specified tools, or correctly soldered.
Imperfect connections could result in a short circuit, fire, or malfunction.
● Tighten the terminal screws within the specified torque range. Undertightening may cause a drop, short
circuit, fire, or malfunction. Overtightening may cause a drop, short circuit, or malfunction due to damage to
the screws or conversion unit.
● Make sure that no foreign matter such as sawdust or wiring debris enters the conversion unit. Such debris
could cause fire, damage, or malfunction.
● Do not reverse the polarity (+ / -). Doing so can cause an explosion or damage.
A - 4
[Startup and Maintenance Precautions]
DANGER ● Do not touch any terminal while power is on. Doing so will cause electric shock. ● Shut off the external power supply (all phases) used in the system before cleaning the conversion unit or
retightening the terminal or unit mounting screws. Not doing so could result in an electric shock.
Undertightening may cause a drop or malfunction. Overtightening may cause a drop, short circuit, or
malfunction due to damage to the screws or conversion unit.
CAUTION ● Never try to disassemble or modify the conversion unit. It may cause a product failure, operation failure,
injury, or fire.
● Use any radio communication device such as a cellular phone or a PHS phone more than 25 cm away from
the conversion unit in all directions. Not doing so may cause a malfunction.
● Shut off the external power supply (all phases) used in the system before installing or removing the
conversion unit. Not doing so may cause the unit to fail or malfunction.
● Before handling the conversion unit, always touch grounded metal, etc. to discharge static electricity from
human body. Not doing so may cause the unit to fail or malfunction.
● Do not directly touch the conductive parts and electronic components of the conversion unit. Doing so could
cause the unit to malfunction or fail.
[Disposal Precautions]
DANGER ● A capacitor is mounted into the conversion unit. Do not incinerate the conversion unit, or the capacitor may
burst. For disposal of the conversion unit, request for the specialized industrial waste disposal service who

1. OVERVIEW
By using this conversion unit (model: DG2GWY31), the controller section of a system can be upgraded from
the SSCNET compatible controller (A series Motion controller/Q series Motion controller/AD75M Positioning
module/QD75M Positioning module) to the SSCNET III/H compatible controller (QDS Motion
controller/Q170MS Stand-Alone Motion controller/Simple Motion module) and SSCNET III compatible
controller (QD Motion controller/Q170M Stand-Alone Motion controller). The SSCNET compatible servo
amplifiers (MR-J2S-B/MR-J2M-B/MR-J2-B/MR-H-B/MR-J4-B-RJ020+MR-J4-T20) in the same system do
not need to be upgraded simultaneously.
Since the controller and drive sections can be upgraded independently, the potential risks at upgrading can
be reduced and the machine halt time can be shortened.
The range of upgrading is flexible since the drive section can be upgraded by SSCNET line (max. 16 axes).
Existing design assets can be used.

5. SETTING AND PROCEDURE BEFORE STARTING OPERATIONS
The conversion unit firmware has the MR-J4-B module function and the Q Motion module function.
The MR-J4-B module function receives position commands, etc. from the QDS Motion controller/Q170MS
Stand-Alone Motion controller/Simple Motion module. Then, the Q series Motion module function sends the
commands to the actual servo amplifier.
The Q series Motion module function also manages the system settings (axis configuration information) and the
servo parameters in the conversion unit.

POINT
In the AD75M Positioning module, "MR-J2S-B" cannot be set for servo series as follows. Even when using MR-
J2S-B, set "MR-J2-B" for the servo series, but in the conversion unit, set "MR-J2S-B" for the amplifier model.
[Servo series setting in AD75M Positioning module (GX Configurator-AP) ]
[Servo model setting in conversion unit (MT Developer2) ]
When setting "MR-J2-B" for the servo series in AD75M Positioning module, the number of feedback pulses be
comes "16384 [pulse]". However, in the system replaced with Simple Motion using the conversion unit, the num
ber of feedback pulses for MR-J2S-B becomes "131072 [pulse]" (equivalent to the resolution of motor compatibl
e with MR-J2S-B).
Therefore, when replacing AD75M Positioning module, review the "number of pulses per revolution" set for the
electronic gear of Simple Motion MR-J2S-B. Refer to the POINTs of Chapter 5.3.2 (1) or 5.3.3 (1) for the numb

5.4 Restrictions
1) Electronic gear of the Motion controller/Simple Motion module
Utilize the electronic gear setting (number of pulses per revolution/movement amount per revolution) from
the source Motion controller to the Motion controller/Simple Motion module.
2) Applicable operating system software
The applicable QDS Motion controller/Q170MS Stand-Alone Motion controller operating system is SV13 or
SV22.
The applicable QD Motion controller/Q170M Stand-Alone Motion controller operating system is SV13, SV22
or SV43.
Any other custom operating system is not applicable.
3) Precaution for converting parameters
When converting parameters, cross-check the parameters and eliminate errors before writing the setting to
the conversion unit.
4) Interface with peripheral devices
Only USB communication is available for communication with the engineering software (MELSOFT MT
Works2).
MR Configurator2 is not connectable to the conversion unit and the servo amplifier.
5) Communication The conversion unit limits the communication cycle to "3.555 ms". Therefore, set the operation cycle of the
QDS Motion controller to "3.555 ms". Set the operation cycle setting for the RD77MS Simple Motion module to "3.555 ms", and for the QD77MS
Simple Motion module to "1.77 ms". One conversion unit can convert SSCNET for up to 16 axes.
Two conversion units are required for conversion of 17 to 32 axes. The conversion unit sends the data received from the Motion controller/Simple Motion module to the servo
amplifiers with a delay of one communication cycle. The servo amplifiers also send data with a one-cycle delay.
The delay may affect machine accuracies for the axes used for interpolation control or synchronous control. Therefore, collectively replace all the servo amplifiers in the same line.
Test the operation when the deviation counter value or the actual current value is used because the data is sent by the servo amplifiers with a one-cycle delay.
Test the operation when the speed-position control command is used because the positioning accuracy may be changed.
5. SETTING AND PROCEDURE BEFORE STARTING OPERATIONS
81
6) Shutting off the control for the servo amplifier If the control for a servo amplifier is shut off, communications with the SSCNET stations subsequent to the
station of this servo amplifier are disabled. The following shows an example in which the control for the servo amplifier on the sixth station (d6) on the SSCNET CN1 line is shut off.

When restoring communication after the control for the servo amplifier is shut off, temporarily turn off the
power for the controls of the Motion controller, Simple Motion module, conversion unit, and servo amplifier
and then simultaneously turn them on.
7) Servo amplifier adjustment
For adjusting servo amplifiers, use MR Configurator to adjust the servo gain. Write the adjustment result to
the conversion unit using MELSOFT MT Works2. Servo parameters are managed by the conversion unit. If
the adjustment result is not written to the conversion unit after servo amplifiers are adjusted, the servo
parameters will return to the previous value by turning off and on the conversion unit. 8) Servo parameters written to the destination Motion controller/Simple Motion module (MR-H-B/MR-J2-B
compatible)
The following servo parameters for the destination Motion controller/Simple Motion module (after replacement)
must be matched to the conversion unit. Conversion unit MR-H-B/MR-J2-B Servo parameters
Destination Motion controller/Simple Motion module MR-J4-B Servo parameters
No. Name No. Name Initial value
1 Amplifier settings PA03 Absolute position detection system
0 (Disabled/INC)
7 Rotation direction selection PA14 Rotation direction selection 0 (CCW or positive direction in positioning address increase)
For upgrading the A/Q series Motion controller (OS: SV13/SV22), use the project diversion function of
MELSOFT MT Works2 for data preparation for the destination Motion controller.
In that case, the servo amplifier is replaced by MR-J4-B, but the servo parameters are initialized for the axes
of a source amplifier MR-H-B / MR-J2-B (*1), so check the above parameters, and set the parameters in the
destination Motion controller.
(*1) For axes where the source amplifier is MR-J2S-B/MR-J2M-B, the setting data is retained when the servo
amplifier is replaced by MR-J4-B, so the above operation is not required.
5. SETTING AND PROCEDURE BEFORE STARTING OPERATIONS

9) Turning the power off/on
Turn on the control circuit power supply for the Motion controller, Simple Motion module, conversion unit,
and servo amplifier simultaneously to start the system.
When resetting the Motion controller/Simple Motion module, or when powering them up again, power up the
conversion unit as well.
When wire breakage occurs for the SSCNET cable and SSCNET III cable and when the cables are
reconnected, power up the Motion controller/Simple Motion module and conversion unit again.
Do not turn the power off/on for the controls of the servo amplifier during the initial communication. 10) Simple Motion module
Home position return
When performing a home position return with the Simple Motion module, do so one axis at a time.
[Md. 106] Servo amplifier software number

5.5 Precaution for Specification Difference in the In-Position Range of the Conversion Unit, DG2GWY31
5.5.1 Setting In-Position Range Servo parameter "in-position range" setting methods differ between the existing SSCNET compatible Motion controller (A/Q series Motion controller) and conversion unit, DG2GWY31. When the setting value of the existing "in-position range” is diverted to the conversion unit, the output timing of in-position signal ON/OFF may change and this may affect machine operation.
When the in-position signal is not used in the existing SSCNET compatible Motion controller
(A/Q series Motion controller), setting value of "in-position range" does not need to be changed.
[Supplementation] Setting the in-position range for the existing AD75M/QD75M Positioning module is in the pulse unit only, so
the same as that of conversion unit. (1) Setting the in-position range for the existing SSCNET compatible Motion controller
Input the in-position range of the existing SSCNET compatible Motion controller in unit (mm, inch, degree, or
pulse) set in servo data "unit setting". The set in-position range is set for the parameter No. 20 (in-position
range) on SSCNET compatible servo amplifier side in pulse by multiplying the electronic gear (number of
pulses per revolution (AP)/movement amount per revolution (AL) by the unit scaling factor (*1)(AM)).
< Converting the in-position range setting value of existing SSCNET compatible Motion controller into pulse >
In-position range (pulse unit conversion)
= In-position range (setting value) × AP
AL×AM
Example: When the electronic gear is AP=131072 [pulse], AL=1000.0 [μm], AM=1 and the in-position
range is set to "10.0 [μm]", the value to be set for the parameter No. 20 (in-position range) on servo
amplifier side is "1310 [pulse]".
Setting range of the existing SSCNET compatible Motion controller “in-position range" is as follows.
1 × AL×AM
AP
≤In-position range (setting value) ≤ 32767 × AL×AM
AP
Example: The setting range is 0.1 [μm] to 249.9 [μm] when set to AP=131072 [pulse], AL=1000.0 [μm],
AM=1. (The setting range may be affected by the electronic gear.)
(*1) AM (unit scaling factor) is not supported for Q series Motion controller.
5. SETTING AND PROCEDURE BEFORE STARTING OPERATIONS
84
(2) Setting in-position range when the conversion unit is used
When the conversion unit is used, the servo parameter "in-position range" set for a new SSCNET III(/H)
compatible controller (QDS Motion controller, etc.) is not used, but "in-position range" set for the conversion
unit is used.
The in-position range set for the conversion unit is set for the parameter No. 20 (in-position range) on
SSCNET compatible servo amplifier side in pulse.
For the in-position range, the minimum setting values of each unit, 0.1 [μm], 0.00001 [inch], and 0.00001
[degree], are handled as 1 [pulse] (integer value).
<How to convert the conversion unit in-position range setting value into the integer value>
In mm unit (minimum: 0.1 [μm])
In-position range (integer value) [pulse] = in-position range (setting value) [μm] × 10
Example: When "mm" unit is set for the conversion unit and "in-position setting" is set to "10.0
[μm]", the value to be set to the parameter No. 20 (in-position range) on servo amplifier side is "100
[pulse]".
The following shows the setting range of the conversion unit "in-position range".
< Setting range of the conversion unit "in-position range" >
1 ~ 32767 [pulse]
When the "in-position range" set for the conversion unit is converted into pulse (integer value)
with no error, the setting value of "in-position range" does not need to be changed.
When ON timing of the in-position signal changes from that of existing facility with the error,
refer to Chapter 5.5.2 (How to Change the In-Position Range Setting of Conversion Unit) and review the setting value.
5.5.2 How to Change the In-Position Range Setting of Conversion Unit
1) Initializing unit setting and electronic gear
Change the servo data "unit setting", "number of pulses per revolution (AP)", and "movement amount per
revolution (AL)" to the default values (*1) as follows before changing the "in-position range" setting of
conversion unit, so that the entire "in-position range", 1 to 32767 [pulse] can be set.
Unit setting: 3 (pulse)
Number of pulses per revolution (AP): 20000 [pulse]
Movement amount per revolution (AL): 20000 [pulse] 2) Setting in-position range
Set the in-position range and perform the "Project Batch Check/Conversion". Remove the errors if required. 3) Writing the parameter to the conversion unit
Write the parameter to the conversion unit and turn the power of conversion unit off/on.
(*1) The servo data "unit setting", "number of pulses per revolution (AP)", and "movement amount per revolution (AL)" are not used for controlling the conversion unit, so changing the setting value does not affect the system operation.
5. SETTING AND PROCEDURE BEFORE STARTING OPERATIONS
85
The following shows the screen of in-position range setting (example).
< Default setting of the unit setting, number of pulses per revolution and movement amount per revolution for
the conversion unit > [Before default setting] The following shows that the in-position range may not be set to 1 to 32767 [pulse] depending on the setting values of "unit setting", "number of pulses per revolution", and "movement amount per revolution".
[After default setting] Changing the "unit setting", "number of pulses per revolution", and "movement amount per revolution" to the default enables the in-position range to be set to 1 to 32767 [pulse].
Before default
The narrowed in-position range of "0.1 to 249.9 [μm]" (1 to 2499 [pulse]) is resulted in against "1 to 32767 [pulse]" for the conversion unit.
After default
After setting to the default, the entire in-
position range of conversion unit, 1 to
32767 [pulse] can be input.
5. SETTING AND PROCEDURE BEFORE STARTING OPERATIONS
86
Precaution
< Remedies for an error occurs while performing the "Project Batch Check/Conversion" >
After the "unit setting", "number of pulses per revolution", and "movement amount per revolution" are changed to the
default values, the setting value of servo data such as "JOG operation limit value", etc. may go out of the setting range.
In that case, change the setting value to the default to be within setting range.
The servo data is not used for controlling the conversion unit, so changing the setting value does not affect the system
operation.
< Setting the out-of-setting-range servo data (example) >
Set "JOG operation
limit value" to the default.

SSCNET configurations between controller and conversion unit do not match - probably setting the wrong
axes and station numbers (supposed to be set to SSCNET line 1, station numbers: d9 to d16, not to
SSCNET line 2, station numbers: d1 to d8).
As shown in the above, the critical error 1350 (operation cycle setting error) occurs in the controller due to
the incorrect communication phase when the SSCNET configurations differ between the controller and

To prove the compliance with the EMC and Low Voltage Directives, manufacturers must issue an EC
Declaration of Conformity and the products must bear a CE marking.

(2) Installation to the control panel
The conversion unit is an open type device. Ensure the conversion unit is installed inside a control panel for
use. Also, install the remote stations of each network inside the control panel.
Waterproof type remote stations can be installed outside of the control panel.
Installing the conversion unit inside a control panel ensures both safety and effective shielding of
electromagnetic noise generated by the conversion unit.
1) Control panel
(a) Use a conductive control panel.
(b) When attaching the control panel's top plate or base plate using bolts, mask the area used for
grounding so that the area is not painted.
(c) To ensure good electrical contact with the control panel, mask the mounting bolt area of the inner
plate in the control panel so that contact between surfaces can be ensured over the widest possible
area.
(d) Ground the control panel with a thick wire to ensure a low impedance connection to ground even at
high frequencies.
(e) Holes in the control panel must measure 10 cm or less in diameter, or radio frequency noise may be
emitted.
In addition, because radio waves leak through a clearance between the control panel door and the
main unit, reduce the clearance as much as practicable.
2) Connection of power line and ground wire
(a) Provide a grounding point near the FG terminals. Ground the FG terminals with the thickest and
shortest possible wire (wire length: 30 cm or shorter, diameter: 2 mm or less).
(b) Twist the grounding wire from the grounding point with the power supply wire. This enables more
noise from the power supply wire to run off to the ground. However, when a noise filter has been
installed on the power supply wire, twisting with the grounding wire is not required.
