What to do if my YASKAWA Z1000 is overloaded?
If the thermal sensor of the YASKAWA Controller drive triggered overload protection, reset the drive by pushing the Reset key on the keypad or cycle the power supply.
What causes a motor overload on my YASKAWA Controller?
A motor overload on your YASKAWA Controller can be caused by: * An excessively heavy load: Reduce the load. * Cycle times that are too short during acceleration and deceleration: Increase the acceleration and deceleration times (C1-01 through C1-04). * Driving a general-purpose motor below its rated speed with a high load: Reduce the load, increase the speed, or use a motor specifically designed for low-speed operation.
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 causes a drive overload on a YASKAWA Z1000?
A drive overload on your YASKAWA Controller can be caused by: * An excessively heavy load: Reduce the load. * Cycle times that are too short during acceleration and deceleration: Increase the acceleration and deceleration times (C1-01 through C1-04). * The output voltage being too high: Adjust the preset V/f pattern (E1-04 through E1-10) by reducing E1-08 and E1-10. Be careful not to lower these values excessively, as it can reduce load tolerance at low speeds.
What to do for output phase loss in YASKAWA Z1000?
Output phase loss in your YASKAWA Controller can occur due to: * A disconnected output cable: Check for wiring errors and ensure the output cable is properly connected. Correct any wiring issues. * A damaged motor winding: Check the resistance between motor lines. Replace the motor if the winding is damaged.
What causes a DC bus undervoltage on a YASKAWA Z1000?
A DC Bus Undervoltage error in your YASKAWA Controller can be caused by: * Input power phase loss: The main circuit drive input power is wired incorrectly. Correct the wiring. * Problems with the voltage from the drive input power: Check the voltage and correct it to be within the range listed in the drive input power specifications. If there is no problem with the power supply to the main circuit, check for problems with the main circuit magnetic contactor. * Worn main circuit capacitors: Check the maintenance time for the capacitors (U4-05). Replace either the control board or the entire drive if U4-05 exceeds 90%.
What does control circuit error mean on YASKAWA Z1000 Controller?
A control circuit error on your YASKAWA Controller indicates a self-diagnostic error in the control circuit. Cycle power to the drive. If the problem continues, replace the control board or the entire drive.
Why YASKAWA Controller motor overload?
Motor overload can occur if the load is too heavy, so reduce the load. Also, it can happen if cycle times are too short during acceleration and deceleration. In this case, increase the acceleration and deceleration times (C1-01 and C1-02).
How to fix a ground fault on a YASKAWA Z1000 Controller?
A ground fault in your YASKAWA Controller can be due to several reasons: * Damaged motor insulation: Check the insulation resistance of the motor and replace the motor if necessary. * A short circuit caused by a damaged motor cable: Inspect the motor cable for damage, remove any short circuits, and reapply power. Check the resistance between the cable and the ground terminal, and replace the cable if needed. * Excessive leakage current at the drive output: Reduce the carrier frequency or the amount of stray capacitance.
What to do if my YASKAWA Controller shows a Ground Fault error?
If a current short to ground exceeds 50% of the rated current on the output side of the YASKAWA Controller drive, try resetting the drive by pushing the Reset key on the keypad or cycle the power supply.
