What causes an electronic overload in my ABB PSTX210 and how can I resolve it?
- K
  Kimberly MirandaAug 23, 2025
  An electronic overload occurs when the motor current is too high for an extended period, often due to a high load on the motor shaft. To resolve this: * Examine start conditions and EOL settings. * Correct the reason for the overload. * Ensure the current limit level is not set too low. * Verify the ramp time for start is not too long. * Confirm the correct overload class is used. * Check that the Setting Ie parameter is correct.

How to troubleshoot phase loss in ABB PSTX210 Controller?
- R

  Check that the mains are connected and that no line contactor or breaker is open. Inspect the fuses for all 3 phases, replacing any that are blown. Verify the operation network supply and correct it if there's a power loss on one or multiple phases. Ensure the contactor/breaker or external switch device is closed. If the line contactor opens too quickly at stop, control it with the Run signal relay on terminal 4, adding a time relay before the contactor opens. If Stop Ramp is not necessary, set Stop mode to direct stop.

What to do if my ABB Controller motor does not start when given a start command by the hardwire inputs?
- J
  John RichardsonAug 31, 2025
  First, check the connections for start and stop. Make sure that the start and stop commands are not given at the same time. Ensure that the keypad is not in Local Control mode; if it is, push the R\L-key to change to Remote Control mode. Also, verify that the Fieldbus control parameter is set to No. Finally, reset any active or tripping events.

What does 'Thyristor overload' mean on my ABB Controller?
- P
  Paula ElliottAug 30, 2025
  A thyristor overload indicates that the thyristors are too hot. Check the start conditions and the fans. If possible, decrease the current limit. Allow the temperature of the thyristors to decrease before restarting.

What should I do if my ABB Controller displays 'Heatsink overtemperature'?
- J
  Jessica HowardAug 28, 2025
  Ensure that the fans are functioning correctly and that the airways are free from dirt and dust. Also, verify that the ambient temperature is not too high. If the fault persists after a reset, the heatsink is still too hot and needs to cool down.

What does it mean when my ABB Controller displays 'Ground fault'?
- J
  Jessica ThomasAug 25, 2025
  A ground fault indicates that the sum of the instantaneous line currents in your 3-phase system differs more than the specified value. Examine the motor cables and the motor itself for any issues.
