If your Toshiba Servo Drive displays a Torque Boost Err, adjust the setting at F410.
How do I fix Torque Boost Err on my Toshiba Servo Drives?
If your Toshiba Servo Drive displays a Torque Boost Err, adjust the setting at F410.
What to do if my Toshiba Servo Drives displays Over-Current error?
If your Toshiba Servo Drive displays an Over-Current error, several factors could be responsible. There might be a phase-to-phase short, a defective IGBT, or incorrect ASD output connections to the motor; correct these issues. Avoid starting the ASD into a spinning motor after a power loss. Check for and remove any jams. Ensure the mechanical brake is disengaged during startup or operation. Increase the acceleration/deceleration time if it's too short. Reduce the Voltage Boost setting if it's too high. Adjust the V/f setting. Stabilize any load fluctuations. Allow the ASD to cool if it's overheating. Verify that the ASD and motor are properly matched. If the ASD current exceeds 320% or 340% of the rated FLA during acceleration, reduce the load during acceleration.
Why DC Bus Voltage Exceeds Specifications in my Toshiba Servo Drives?
If your Toshiba Servo Drive's DC Bus Voltage exceeds specifications, avoid starting the ASD into a spinning motor after a momentary power loss. Ensure the incoming commercial power voltage is within the specified range. Increase the deceleration time if it's too short. Install an inductive filter to address voltage spikes at the 3-phase input. Enable the Over-Voltage Stall feature. Check the regeneration system. Stabilize any load fluctuations.
How to fix Over-Heat in Toshiba Servo Drives?
If your Toshiba Servo Drive is overheating, ensure the ASD can cool down by relocating it away from heat sources and clearing any obstructions from the cooling fan vent. If the cooling fan is inoperative, replace it. Also, check if the internal thermistor is disconnected and reconnect it if necessary.
How to troubleshoot Communication Error Interruption in Toshiba Servo Drives?
If you're experiencing a Communication Error Interruption with your Toshiba Servo Drive, it may be due to an improperly programmed ASD, so reprogram it. Review and adjust the communications settings. Also, check and correctly connect all cables.
What causes Motor Overload in Toshiba Servo Drives and how to resolve it?
If your Toshiba Servo Drive shows a Motor Overload error, you may need to adjust the V/f setting. If the motor is locked, unlock it. Avoid continuous operation at low speed. Also, ensure the motor specifications match the load requirements.
What to do if Toshiba Servo Drives displays Under-Current?
If your Toshiba Servo Drive shows an Under-Current, disable detection at F610 or adjust parameter F611.
What to do for Under-Voltage Condition at the 5, 15, or the 24 VDC supply in Toshiba Servo Drives?
If you are facing an Under-Voltage Condition at the 5, 15, or the 24 VDC supply with your Toshiba Servo Drive, replace the defective control board if it is the cause. Reduce the load on the power supply if there's an excessive load. Ensure sufficient input voltage is supplied.
How to resolve Motor Rating Err on Toshiba Servo Drives?
If your Toshiba Servo Drive displays a Motor Rating Err, adjust the settings at F405, F406, or F407.
What to do if Toshiba Servo Drives shows 4-20 Signal Loss?
If the Toshiba Servo Drive indicates a 4-20 Signal Loss, check and repair any misconnections, poor connections, or broken wires. If necessary, reprogram at F201 and related parameters.
