Always apply permissible range of voltage to the each terminal as indicated in this

manual. Otherwise, it could lead to inverter damage.

(4) Operation precautions

When the Auto restart function is selected, stay away from the equipment as a motor willrestart suddenly after an alarm stop.

The Stop key on the keypad is valid only when the appropriate function setting has been

made. Prepare an emergency stop switch separately.

If an alarm reset is made with the reference signal present, a sudden start will occur.

Check that the reference signal is turned off in advance. Otherwise an accident could

occur.

Do not modify or alter anything inside the inverter.

Motor might not be protected by electronic thermal function of inverter.

Do not use a magnetic contactor on the inverter input for frequent starting/stopping of theinverter.

Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby

electronic equipment may be affected.

In case of input voltage unbalance, install AC reactor. Power Factor capacitors and

generators may become overheated and damaged due to potential high frequency noise

transmitted from inverter.

Use an insulation-rectified motor or take measures to suppress the micro surge voltage

when driving 400V class motor with inverter. A micro surge voltage attributable to wiring

constant is generated at motor terminals, and may deteriorate insulation and damagemotor.

Before operating unit and prior to user programming, reset user parameters to default

settings.

Inverter can easily be set to high-speed operations, Verify capability of motor or

machinery prior to operating unit.

Stopping torque is not produced when using the DC-Break function. Install separate

equipment when stopping torque is needed.

(5) Fault prevention precautions

Provide a safety backup such as an emergency brake which will prevent the machine

and equipment from hazardous conditions if the inverter fails.

(6) Maintenance, inspection and parts replacement

Do not conduct a megger (insulation resistance) test on the control circuit of the inverter.

Refer to Chapter 14 for periodic inspection (parts replacement).

(7) Disposal

Handle the inverter as an industrial waste when disposing of it.

(8) General instructions

Group Code Parameter Name Setting Range Initial Unit

0.00 [Frequency Command] - 0 ~ 400 0.00 HzDrive group

Frq [Frequency mode] 0 0 ~ 7 0

Set Frq [Frequency mode] to 0 {Frequency setting via Keypad 1}. Set the desired frequency in 0.00 and press the Prog/Ent () key to enter the value intomemory.

The value is settable less than F21 [Max frequency].

When remote keypad is connected, keypad keys on the body are deactivated.

Keypad Frequency setting 2


0.00 [Frequency Command] - 0 ~ 400 0.00 HzDrive group

Frq [Frequency mode] 1 0 ~ 7 0

Set Frq [Frequency mode] to 1{Frequency setting via Keypad 2}. In 0.00, frequency is changed upon pressing the Up ()/Down () key. In this case,UP/Down keys serve as a potentiometer. The value is settable less than F21 [Max frequency].

When remote keypad is connected, keypad keys on the body are deactivated.

I 1 (Filter time constant for NV input): Effective for eliminating noise in the frequency

setting circuit. Increase the filter time constant if steady operation cannot be performed

due to noise. A larger setting results in slower response (t gets longer).

I 2 ~ I 5: Setting input range and corresponding frequency to -10V ~ 0V V1 input

voltageEx) when minimum (-) input voltage is -2V with corresponding frequency 10Hz and Max

voltage is 8V with run freq. 50Hz.
