Series/Yaskawa inverter fault code Yaskawa inverter fault code
Abnormal indication, fault content, description of processing countermeasures, etc.
During low-voltage operation of the main circuit, the main circuit voltage is lower than the low-voltage detection standard, (instantaneous power failure protection) Check the power supply voltage and wiring
Protection) The low voltage detection standard level is about less than the level about
Control circuit low voltage The control circuit voltage is lower than the low voltage detection standard) Check the power supply capacity
Internal When the electromagnetic contactor fails to operate, the precharge contactor is open
Instantaneous power failure is being detected) The main circuit DC is lower than the low voltage detection standard) The precharge contactor) The control circuit voltage is lower than the low voltage detection standard
Overcurrent The output current of the inverter exceeds the standard) Check whether the impedance insulation of the motor is normal) During extended acceleration and deceleration
Ground fault The ground current on the output side of the inverter exceeds the rated current of the inverter) Check whether the insulation of the motor has deteriorated
) Check whether the wiring between the inverter and the motor is damaged
If the DC voltage of the overvoltage main circuit is higher than the overvoltage detection standard, please extend the deceleration time and install a brake controller and brake motor
Load short circuit Short circuit on the output side of the inverter Check whether the insulation and impedance of the motor are correct
Fuse is broken) Main circuit crystal module is faulty) DC circuit fuse is blown) Check whether the crystal module is normal
) Check whether there is a short circuit on the load side , grounding, etc.
The heat sink is overheated. The temperature of the cooling fan of the crystal module exceeds the allowable value. Check whether the fan function is normal and whether the surroundings are within the rated temperature
The motor is overloaded and the output current exceeds the motor overload capacity. Reduce the load
br/> The output current of the inverter is overloaded and exceeds the rated current value of the inverter. Reduce the load and extend the acceleration for 1 minute
Input under-term) Input power supply of the inverter is out of phase) Input voltage three-phase unbalance) Check whether the power supply voltage is normal ) Check whether the input terminal screws are pinned
Output shortage item The power supply on the output side of the inverter is out of phase) Check whether the output terminal screws and wiring are normal) Motor three-phase impedance detection
Abnormal braking transistor, poor braking transistor action Send the inverter for repair
The brake controller is overheated. The temperature of the brake controller is higher than the allowable value. Check the braking time and the use of the braking resistor
