What causes an Input Phase Loss in YASKAWA CIMR-VCBA0002 DC Drives?
An input phase loss in YASKAWA DC Drives can be caused by: * Input voltage drop or phase imbalance. * One of the input phases being lost. * Loose wires at the drive input. To resolve this, check the power supply and ensure that all cables are properly fixed to the correct terminals.
What to do if YASKAWA DC Drives display DC Overvoltage?
If your YASKAWA DC Drives are showing a DC Overvoltage, it means the DC bus voltage is too high. This can be due to: * A deceleration time that is too short. * Stall prevention being disabled. * A broken braking chopper/resistor. * Unstable motor control in OLV. * Too high 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 parameters and adjust torque/slip compensation, and verify the power supply voltage meets the drive's specifications.
What causes a Ground Fault in YASKAWA CIMR-VCBA0002?
A ground fault in YASKAWA DC Drives indicates that the ground leakage current has exceeded 50% of the drive's rated output current. This may be due to broken cable or motor insulation, or excessive stray capacitance at the drive output. To address this, check the output wiring and motor for shorts or broken insulation, replacing any damaged parts, and reduce the carrier frequency.
Why is my YASKAWA CIMR-VCBA0002 showing a Motor Overload?
A motor overload in YASKAWA DC Drives can be caused by: * The motor load being too heavy. * Operating the motor at low speed with a heavy load. * Cycle times of accel./decel. being too short. * An incorrect motor rated current setting. To resolve this, reduce the motor load, use a motor with external cooling and set the correct motor in parameter L1-01, check the sequence, and verify the rated current setting.
What causes YASKAWA CIMR-VCBA0002 to display a Drive Overload?
A drive overload in YASKAWA DC Drives can occur because: * The load is too heavy. * The drive capacity is too small. * There is 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, as the overload capability is reduced at low speeds.
Why do YASKAWA DC Drives show a DC Undervoltage?
A DC Undervoltage in YASKAWA DC Drives indicates that the voltage in the DC bus has fallen below the undervoltage detection level (L2-05). This can happen if the power supply has failed, one input phase has been lost, or the power supply is too weak. To fix this, check the power supply and make sure it is strong enough.
What to do if YASKAWA DC Drives show Controller Undervoltage?
If YASKAWA DC Drives display Controller Undervoltage, it indicates that the drive's controller power supply voltage is too low. Cycle power to the drive and check if the fault reoccurs. If it continues, replace the drive.
What should I do if YASKAWA CIMR-VCBA0002 DC Drives display a DC Charge Circuit Fault?
If YASKAWA DC Drives display a DC Charge Circuit Fault, it indicates that the charge circuit for the DC bus is broken. Cycle power to the drive and check if the fault reoccurs. If it does, replace the drive.
What does 'Drive Disable' mean on YASKAWA CIMR-VCBA0002?
If YASKAWA DC Drives show 'Drive Disable', it means both Drive Disable inputs are open, which safely disables the drive output, preventing the motor from starting. This could be because the upper controller's safety device disabled the drive. To fix this, determine why the upper controller disabled the drive, remove the cause, and restart. Also, check the wiring. If the Drive Disable function is not used for EN60204-1, terminals HC, H1, and H2 must be linked.
How to troubleshoot Heatsink Overheat in YASKAWA CIMR-VCBA0002 DC Drives?
A heatsink overheat in YASKAWA DC Drives can be caused by: * A high surrounding temperature. * A cooling fan that has stopped working. * A dirty heatsink. * Restricted airflow to the heatsink. To fix this, check the surrounding temperature and install cooling devices if needed, inspect the drive's cooling fan, clean the heatsink, and ensure there is adequate airflow around the heatsink.
