  uwelchAug 17, 2025
  If your Toshiba Inverter is in 'Emergency Off' mode, you need to investigate and correct the stop condition. Ensure the reset function is operating correctly, especially if the reset button was pressed twice at the EOI. Also, identify and address the source of any remote EOFF commands. Finally, perform a reset of the ASD.

  John CruzAug 21, 2025
  If your Toshiba Inverter is overheating, implement cooling solutions to reduce its temperature. Relocate the ASD away from heat sources. Clear any obstructions to the cooling fan vent. If the cooling fan is inoperative, repair or replace it. If the internal thermistor is disconnected, reconnect or replace it.

  To address an ASD Overload in your Toshiba Inverter, lower the carrier frequency setting. Reduce the load to within the ASD's capability. Increase the acceleration time setting. Adjust the DC damping rate to a suitable level. Avoid starting the motor into a spinning load after a momentary power failure. Ensure the ASD is suitable for the application.

What to do if my Toshiba P9 ASD Inverter shows an Over-Current error?
- V
  veronicastevensNov 13, 2025
  If your Toshiba Inverter is showing an over-current error, several factors could be responsible. You should check for defective IGBTs (U, V, or W) and replace them if necessary. Ensure the ASD output to the motor is correctly connected and check for any phase-to-phase shorts, correcting them as needed. Avoid starting the ASD when the motor is already spinning. Clear any jams in the motor or machine. Make sure the mechanical brake is not engaged during ASD start or run. Increase acceleration and deceleration time settings if they are too short, and reduce the voltage boost setting if it's too high. Stabilize the load to prevent fluctuations. Improve cooling or ventilation for the ASD. Finally, check for and repair any damaged or disconnected cables, especially when operating in PG Feedback ...
