To Next PageTo Next PageWhat 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.
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 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.
