What to do if Aerotech Controller amplifier faults and “ENA” LED de-energizes?

  Mr. Jesse Fry MDAug 11, 2025
  If the Aerotech Controller's amplifier faults and the ENA LED de-energizes, this could be due to several reasons. It may be caused by exceeding the RMS current, in which case you should run the system at a lower current. Another cause could be an over-temperature condition; turn off the amplifier and allow it to cool down, then ensure better ventilation. It can also be caused by incorrectly set axis parameters or attempting to exceed system capabilities, or a motor feedback problem (encoder or Hall inputs).

  If the Aerotech Epaq controller does not respond and shows no indicators, check if the power is connected to the Epaq. Also, verify that the power switch is turned on. Finally, inspect the AC power fuse at the AC inlet on the rear of the Epaq to see if it has blown.

Why does Aerotech Ensemble Epaq Controller amplifier fault when motor decelerates?
- K
  Kyle GuzmanAug 23, 2025
  If the Aerotech Controller amplifier faults (the “ENA” LED de-energizes) when the motor decelerates, it may be due to a bus over voltage detected or an incorrect parameter setting.

What to do if Aerotech Ensemble Epaq Controller brushless motor will not spin?
- W
  Whitney WalshAug 29, 2025
  If the brushless motor of your Aerotech Controller will not spin, it might be because the motor phases A, B, and C are connected incorrectly relative to the Hall A, Hall B, and Hall C inputs.

What causes Encoder Feedback Fault in Aerotech Ensemble Epaq Controller?
- M
  Mitchell GutierrezSep 4, 2025
  An encoder feedback fault in the Aerotech Controller could be due to a bad encoder feedback device or a low power supply voltage at the encoder.
