What to do if my Toshiba Servo Drives shows ASD Overload?
- L
  Linda WashingtonAug 21, 2025
  If your Toshiba Servo Drive is showing an ASD Overload, it could be due to several reasons. The carrier frequency might be too high, so try reducing it. There might be an excessive load on the ASD, so reduce the load. If the acceleration time is too short, increase it. A high DC damping rate can also cause this, so reduce it. Avoid starting the motor into a spinning load after a power failure. Lastly, ensure the ASD is properly matched to the application requirements.

What to do if my Toshiba Servo Drives displays Over-Current error?

  Billy EdwardsAug 22, 2025
  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?
- J
  Jacqueline WatsonAug 25, 2025
  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.

  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.

What causes Motor Overload in Toshiba Servo Drives and how to resolve it?
- P
  Pamela RamirezAug 29, 2025
  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.

How to fix Autotuning Err on Toshiba Servo Drives?
- A
  Alexandra OwensAug 31, 2025
  If your Toshiba Servo Drive shows an Autotuning Err, it could be due to inconsistent autotune readings, so repair the inconsistencies. Ensure a 3-phase motor is being used. Adjust the settings at F400 or F410 – F413. If the motor rating is significantly smaller than the ASD, replace it with a motor that meets the rating required. Reconfigure the ASD output cabling if it is too small, too long, or housed in a cable tray with interfering EMF. Make sure the motor is not running during Autotune.
