The torque limit was reached during deceleration for longer than 3 sec. when in Open Loop Vector control because the load inertia is too big, the torque limit is too low, or the motor parameters are wrong. Check the load, set the torque limit to the most appropriate setting (L7-01 through L7-04), and check the motor parameters.
What does 'tion al Fault' mean on a YASKAWA J1000 CIMR-JC?
An external fault was tripped by the upper controller via an option card. Remove the fault cause, reset the fault and restart the drive. Check the upper controller program.
How to fix Ground Fault in YASKAWA Controller?
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 causes External Faults in my YASKAWA J1000 CIMR-JC Controller?
An external fault was triggered by an external device via one of the digital inputs S1 to S6, or the digital inputs are set up incorrectly. Find out why the device tripped the EF, remove the cause and reset the fault. Check the functions assigned to the digital inputs.
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.
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.
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 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.
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 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.
