How to troubleshoot CAN Open comms trip on ABB ACS255?
To troubleshoot a CAN Open comms trip on your ABB Controller, check that the network master/PLC is still operating and inspect the connection cables. Increase the value of parameter 3018 to a suitable level.
What causes a lost 4-20mA signal on ABB ACS255?
If you've lost a 4-20mA signal on your ABB Controller, check the signal source and wiring to the ACS255 terminals.
What does motor PTC over temperature mean on ABB Controller?
A motor PTC over temperature indication on your ABB Controller means that the connected motor PTC device has caused the drive to trip.
What to do if ABB ACS255 shows instantaneous over current due to excess motor load?
If the fault occurs on drive enable, inspect the motor and its connection cable for phase-to-phase and phase-to-earth short circuits. Verify the load isn't jammed, blocked, or stalled mechanically. Ensure the motor nameplate parameters are correctly entered in parameters 9905, 9906, and 9907. If operating in Vector mode (Parameter 9903 – 0 or 1), also check the motor power factor in parameter 9915 and ensure an autotune has been successfully completed for the connected motor. Reduce the Boost voltage setting in parameter 2603. Increase the ramp up time in parameter 2202. If the connected motor has a holding brake, ensure the brake is correctly connected and controlled, and is releasing correctly. If the fault occurs when running in Vector mode (parameter 9903 – 0,1,3), reduce the speed loo...
