1. Transportation and installation of machine When machine transports, it is nessary to fix the outer cylinder and base of frame.

Note: When machine finished installation , make sure to remove the bolts which fix on the outer cylinder and base of frame.

2. The foundation installation of machine (1). Be sure to keep machine in horizon while it is installed on unsmooth ground, especially keep height horizon on both left and right sides,Use horizontal meter if necessary for the accuracy in horizon. (2). The 4 pieces basement bolts which under the bottom of mahine should be fixed exactly on foot cushion while installing the machine, by this, it can prevent machine from vibration during extract, and avoid a badly damage to the machine.

Fix or remove boltswhen machine transportationor installation.

Output

Fault DC Volt. Low

The main circuit DC voltage becomes lower than the low voltage detection level (Cn-34). Operation

Fault Over Current

The inverter output current becomes approx. 200% and above the inverter rated current. Operation

Fault Ground Fault

A ground fault occurs at the inverter output side and the ground-fault current exceeds approx. 50% of the inverter rated current. Operation

Fault Over Voltage

The main circuit DC voltage becomes excessive because of regeneration energy caused by motor decelerating. Operation

Fault Over Heat The temperature of the cooling fin reaches the detection level. Operation

Fault Motor Over Load

Motor overload is detected by the electronic thermal relay. (motor protection) Operation

Fault Inverter Over Load

The electronic thermal sensor detects inverter overload while the output current exceeds 112% of rated value. (inverter protection) Operation

Fault Over Torque

Over torque is detected while the output current is larger than or equal to the setting of Cn-26. (machine protection) Operation

Error Causes Action to Be Taken

‧ Power capacity is too small. ‧ Voltage drop due to wiring resistance. ‧ A motor of large capacity connected to the same power

system has been started. ‧ Defective electromagnetic contractor.

‧ Check the source voltage and wiring. ‧ Check the power capacity and power system.

‧ Extremely rapid accel. ‧ Short-circuit or ground- fault at the inverter output side. ‧ Motor of a capacity greater than the inverter rating

has been started. ‧ High-speed motor and pulse motor has been started.

‧ Extend the accel. time. ‧ Check the load wiring.

‧ Motor dielectric strength is insufficient. ‧ Load wiring is not proper.

‧ Check the motor wiring impedance and the load wiring.

‧ Insufficient deceleration time. ‧ High input voltage compared to motor rated voltage.

‧ Extend the accel. time. ‧ Use a braking resistor.

‧ Defective cooling fan. ‧ Ambient temperature rise ‧ Clogged filter.

‧ Check for the fan, filter and the ambient temperature.

‧ Overload, low speed operation or extended accel. time. ‧ Improper V-f characteristic setting

‧ Measure the temperature rise of the motor. ‧ Decrease the output load. ‧ Set proper V/f characteristic.

‧ Improper rated current (Cn-09) setting ‧ Set proper V/f characteristic. ‧ Set proper rated current (Cn-09) ‧ If inverter is reset repetitively before fault

removed, the inverter may be damaged.

‧ Machine errors or overload ‧ Check the use of the machine. ‧ Set a higher protection level (Cn-32).

‧ Fault input of external signal , , , and . ‧ Identify the fault signal using Un-11.

‧ Disturbance of external noise ‧ Excessive impact or vibration

‧ Reset NVRAM by running Sn-03. ‧ Replace the control board if the fault can’t be

cleared.

‧ Improper setting of ASR parameter or over-speed

protection level. ‧ Check the parameters of ASR and the

protection level.

‧ The PG wiring is not properly connected or

open-circuit. ‧ Check the PG wiring.

‧ Improper setting of ASR parameter or speed

deviation level. ‧ Check parameters of ASR and speed deviation

level. ‧ External noise

‧ Excessive vibration or impact Communication wire ‧ Not properly contacted

‧ Check the parameter setting, including Sn-01, Sn-02. ‧ Check if the comm. wire is not properly contacted. ‧ Restart, if fault remains, please contact to us.

Error Causes Action to Be Taken

‧ Input voltage drop ‧ Measure the main circuit DC voltage, if the

voltage is lower allowance level, regulate the input voltage.

‧ Input voltage rise ‧ Measure the main circuit DC voltage, if the

voltage is higher than allowance level, regulate the input voltage.

‧ Overload ‧ Cooling fan fault. Ambient temperature rises. ‧ Clogged filter.

‧ Check for the fan, filter and the ambient temperature.

‧ Machine error or overload ‧ Check the use of the machine. ‧ Set a higher protection level (Cn-32).

‧ Insufficient Accel./Decel. Time ‧ Overload ‧ Excessive load impact occurs while operating

‧ Increase Accel./Decel. Time. ‧ Check the load.

‧ Operation sequence error ‧ 3-wire/2-wire selection error

‧ Check the circuit of system ‧ Check the setting of system parameters Sn-25,

26, 27, and 28.

‧ External noise ‧ Excessive vibration or impact on Communication wire ‧ Not properly contacted

‧ Check the parameter setting, including Sn-01, Sn-02. ‧ Check if the comm. wire is not properly contacted. ‧ Restart, if fault remains, please contact to us.

‧ Comm. between digital operator and inverter has not been established after system starts for 5 seconds.

‧ Communication is established after system starts, but transmission fault occurs for 2 seconds.

‧ Re-plug the connector of the digital operators. ‧ Replace the control board.

‧ External B.B. signal is input. ‧ After external BB signal is removed, execute the speed search of the inverter.

‧ Inverter KVA setting error. ‧ Set proper KVA value. Be aware of the

difference of 220V and 440V

‧ The value of Sn-25~Sn-28 is not in ascending order (Ex. Sn-25= 05, Sn-28= 02, those are improper setting).

‧Set speed search command of 21 and 22 simultaneously.

‧ Set these values by order (the value of Sn-25 must be smaller than those of Sn-26, 27, 28)

‧ Command 21 and 22 can not be set on two multi-function-input contacts simultaneously.

‧ The values of Cn-02~Cn-08 do not satisfy Fmax ≥ FA ≥ FB ≥ Fmin. ‧ Change the settings.

‧ Upper limit and lower limit setting is incorrect. ‧ Change the settings.

‧ Improper ASR parameter setting or over-torque protection level.

‧ Check the ASR parameter and over-torque protection level.

‧ The circuit of PG is not properly connected or open-circuit. ‧ Check the wiring of PG.

‧ Improper ASR parameter setting or over-torque protection level.

‧ Check the ASR parameter and over-torque protection level.

‧ Bad communication during operator and inverter. ‧The connector is not properly connected. ‧ Check if the connector is not properly connected.

‧ Operator EEPROM error. ‧ Disable load function of operator.

‧ Replace the operator.

‧ Incorrect inverter data format ‧ Communication noise.

‧ Download the data to the operator again. ‧ Check if the connector is not properly connected.

‧ Communication noise ‧ Check if the connector is not properly connected.

‧ Inverter capacity and motor rating are not properly matched.‧ The wiring between inverter and motor is disconnected. ‧ Motor load unbalance.

‧ Correct the inverter/motor capacity ratio, wiring cable and motor load.
