Ground Fault in the YASKAWA Controller occurs when ground leakage current exceeds 50% of the drive's rated output current, cable or motor insulation is broken, or there's excessive stray capacitance at the drive output. Check the output wiring and the motor for short circuits or broken insulation, replacing any broken parts. Reduce the carrier frequency.
What to do if there is Overcurrent in YASKAWA Controller?
Overcurrent in the YASKAWA Controller can occur due to a short circuit or ground fault on the drive output side, an excessively heavy load, short acceleration/deceleration times, incorrect motor data or V/f pattern settings, or switching a magnetic contactor at the output. To resolve this, check the output wiring and motor for shorts or broken insulation, inspect the machine for damages, verify the drive parameter settings, and check the output contactor sequence.
Why is there DC Overvoltage in my YASKAWA J1000 CIMR-JC?
DC Overvoltage in the YASKAWA Controller can occur if the DC bus voltage rises too high due to a short deceleration time, disabled stall prevention, a broken braking chopper/resistor, unstable motor control, or too high an input voltage. To fix this, increase the deceleration time, enable stall prevention via parameter L3-04, ensure the braking resistor and chopper are working, check motor parameter settings, and verify the power supply voltage meets the drive's specifications.
What causes Motor Overload in YASKAWA Controller?
Motor Overload in the YASKAWA Controller is caused by a motor load that is too heavy, operation at low speed with a heavy load, short acceleration/deceleration cycle times, or an incorrectly set motor rated current. To solve this, reduce the motor load, use a motor with external cooling and set the correct motor in parameter L1-01, check the sequence, and check the rated current setting.
What to do if there is Drive Overload in YASKAWA J1000 CIMR-JC?
Drive Overload in the YASKAWA Controller can happen if the load is too heavy, the drive capacity is too small, or there's too much torque at low speed. To resolve this, check the load, ensure the drive is adequately sized for the load, and reduce the load or increase the drive size if operating at low speeds.
Why is my YASKAWA J1000 CIMR-JC Heatsink Overheating?
Heatsink Overheat in the YASKAWA Controller can occur if the surrounding temperature is too high, the cooling fan has stopped working, the heatsink is dirty, or the airflow to the heatsink is restricted. To solve this, check the surrounding temperature and install cooling devices if necessary, inspect the drive cooling fan, clean the heatsink, and ensure proper airflow around the heatsink.
What causes DC Undervoltage in YASKAWA J1000 CIMR-JC?
DC Undervoltage in the YASKAWA Controller occurs when the voltage in the DC bus falls below the undervoltage detection level (L2-05) because the power supply failed, one input phase has been lost or the power supply is too weak. Check the power supply and ensure that it is strong enough.
How to troubleshoot Input Phase Loss in YASKAWA J1000 CIMR-JC Controller?
Input Phase Loss in the YASKAWA Controller is caused by input voltage drop or phase imbalance, loss of one input phase, or loose wires at the drive input. Check the motor wiring, ensure all terminal screws in the drive and motor are properly tightened, and verify the motor and drive capacity.
What does Safe Disable Fault mean on YASKAWA J1000 CIMR-JC Controller?
Safe Disable Fault in the YASKAWA Controller occurs when the drive output is disabled while only one of the Safe Disable inputs is open. This can be due to one channel being internally broken or only one channel being switched off by the upper controller. Check the wiring from the upper controller and ensure that both signals are set correctly. If the signals are correctly set and the alarm persists, replace the drive.
Why am I getting Output Phase Loss on my YASKAWA J1000 CIMR-JC?
Output Phase Loss in the YASKAWA Controller is caused by a disconnected output cable, damaged motor winding, or loose wires at the drive output. It can also occur if the motor is too small (less than 5% of drive current). Check the power supply and ensure that all cables are properly fixed to the correct terminals.
