How to stop motor hunting and oscillation at speeds between 10 and 40 Hz on YASKAWA Controller?
Reduce the setting if insufficient motor torque relative to the size of the load causes hunting. Increase the setting when motor hunting and oscillation occur with a light load. Reduce the setting if hunting occurs when using a motor with a relatively low inductance, such as a high-frequency motor or a motor with a larger frame size.
How to fix Undervoltage error on YASKAWA Controller?
If the DC bus voltage dropped below the level specified in L2-05, the contactor to suppress inrush current in the drive was opened, or there is low voltage in the control drive input power when the drive was stopped and a Run command was entered, you can reset the YASKAWA Controller drive by pushing the Reset key on the keypad or cycle the power supply.
What to do if YASKAWA Controller displays Heatsink Overheat?
If the heatsink temperature exceeded the drive overheat level or the overheat pre-alarm level set to L8-02, reset the YASKAWA Controller drive by pushing the Reset key on the keypad or cycle the power supply.
What to do if YASKAWA Controller motor torque is poor at speeds below 10 Hz?
If motor torque is insufficient at speeds below 10 Hz, increase the setting. If motor hunting and oscillation occur with a relatively light load, reduce the setting.
How to resolve A/D Conversion Error on YASKAWA Z1000?
If an A/D conversion error or control circuit error occurred, reset the YASKAWA Controller drive by pushing the Reset key on the keypad or cycle the power supply.
What causes Current Offset Fault in YASKAWA Controller?
If the YASKAWA Controller drive starts operation while there is a current-detection circuit failure, or the induced voltage remains in the motor (coasting and after rapid deceleration), reset the drive by pushing the Reset key on the keypad or cycle the power supply.
What to do if YASKAWA Z1000 shows Control Circuit Error?
Reset the YASKAWA Controller drive by pushing the Reset key on the keypad or cycle the power supply.
How to fix Motor Overheat Fault (PTC input) on YASKAWA Z1000 Controller?
If the motor overheat signal to analog input terminals A1 or A2 exceeded the fault detection level, reset the YASKAWA Controller drive by pushing the Reset key on the keypad or cycle the power supply.
How to clear Motor Overheat Alarm (PTC input) on YASKAWA Z1000 Controller?
If the motor overheat signal to analog input terminals A1 or A2 exceeded the fault detection level, reset the YASKAWA Controller drive by pushing the Reset key on the keypad or cycle the power supply.
How do I resolve a Control Board Connection Error on my YASKAWA Z1000 Controller?
If there is a connection error between the control board and the drive, reset the YASKAWA Controller drive by pushing the Reset key on the keypad or cycle the power supply.
