Description

F16 :Motor

Overheatin

F16.01 (D)

COMBIACX : Motor maximum temperature reached
Check the thermal sensor wiring and ohm value
Improve the air cooling of the motor
If the warning is present when the motor is cool, then the problem is inside the controller : Replace
it

Speed

problem

F16.02 (A)

COMBIACX : The drive motor has been detected stalled or the encoder is not working

ACEX : The drive motor has been detected stalled or the encoder is not working

Motor

supply

F16.03 (A)

COMBIACX : During drive, motor output voltage is lower than expected
Check the motor power wiring and connections
Check the motor phases for proper insulation with the chassis
Check that MC DRIVE power contact close properly, with a good contact
If no problem is found on the motors, replace the controller

ACEX : During drive, motor output voltage is lower than expected
Check the motor power wiring and connections
Check the motor phases for proper insulation with the chassis
Check that MC DRIVE power contact close properly, with a good contact
If no problem is found on the motors, replace the controller

COMBIACX : Motor voltage feedback circuits are damaged
Check the motor power wiring and connections
If the wiring is correct, the controller is damaged : Replace it

COMBIACX : The motor output voltage is lower than expected, before MC DRIVE switch ON
Check the motor phase to phase impedance
Check the motor power cables connections
