Description:
Runtime error while switching on the current controller. When switching on the controller, a test is made to determine whether or not current can be applied to the motor’s / regenerative choke’s (X5 connection) phases. The currents measured in this phase were too low.
Reaction:
Movement stop by switching off the IGBT output stage and switching on the holding brake.
Cause/Remedy:
X5 connection wiring error: Check if all phases (U, V and W) are properly connected to the X5 connection.
Motor wiring error: Remove the phases (U,V and W) from the X5 connection. Check the phase-phase resistance between U-V, V-W and W-V on the motor line (ACOPOS-sided).The three resistances must be the same and finite. If at least one of the resistances is infinite then the motor or the motor line is defective.
Motor defect: Check the phase-phase resistance between U-V, V-W and W-V right on the motor. The three resistances must be the same and finite. The motor must be replaced if at least one of the resistances is infinite.
Incorrect motor configuration: MOTOR_STATOR_INDUCTANCE too low.
Incorrect motor configuration: MOTOR_CURR_RATED too low.
ACOPOS power stage defect: Replace the ACOPOS servo drive.
The connection check can be deactivated using MOTOR_TEST_MODE.
