What does 'Faulty usage' mean on my ABB Controller?
- PPamela SerranoSep 23, 2025
Do not use jog forward, jog backward, heat motor, or stand-still break functions with an Inside delta motor connection.
What does 'Faulty usage' mean on my ABB Controller?
Do not use jog forward, jog backward, heat motor, or stand-still break functions with an Inside delta motor connection.
What does it mean when my ABB PSTX105 Controller displays 'Ground fault'?
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.
What should I do if my ABB PSTX105 displays 'Locked rotor'?
Examine the bearings of the motor and the load to ensure they run easily. A damaged bearing or a load stock could be the cause.
What does it mean when my ABB Controller displays 'Overvoltage'?
An overvoltage error indicates that the main voltage is too high. Perform a check of the main voltage.
What does it mean when my ABB Controller displays 'Under voltage'?
An undervoltage error indicates that the main voltage is too low. Perform a check of the main voltage.
What does 'High current' mean on my ABB PSTX105?
A high current fault indicates that a fault current, higher than 8 times the softstarter's rated current, has occurred. Check the circuits and the motor for an insulation fault between phases or a ground fault.
What does 'Auto-restart time-out' mean on my ABB PSTX105?
The auto-restart time-out error means that the time between a trip and an auto-restart attempt has exceeded the configured setting. Review the automatic restart parameters and correct them as needed.
Why does my ABB PSTX105 Controller display 'Too long start time'?
This indicates that the time taken to soft start the motor is longer than the set value. Check the starting conditions and current limit.
How do I fix an ABB PSTX105 Controller that shows a blank screen and no LED is active?
First, ensure that the supply voltage is properly connected, referring to the circuit diagram. Also check that the RJ45 plug is connected between the HMI and the softstarter, and that the RJ45 network cable is not damaged.
What to do if my ABB Controller motor is humming or starts without a given start signal?
This issue could be due to a few reasons. If it's a PSTX30...170 model, a bypass relay might be closed due to inaccurate handling. To resolve this, disconnect the operation voltage and the control supply voltage, remove the USB cable if connected, and then reconnect the voltage in the following sequence: first, the control supply voltage on terminals 1 and 2 (refer to chapter 5.1.2), wait 4 seconds, and then connect the operation voltage on terminals L1, L2, and L3. Alternatively, the bypass contactor/relay could be stuck in a closed position, or there might be a shorted thyristor. In either of these cases, it is best to speak to your ABB Sales Office.
