CD1-a
Chapter 7 – Troubleshooting
1.10 - FOLLOWING ERROR
The FOLLOWING ERROR fault corresponds to a following error of the speed loop.
¾ Check that the load is actually adjusted to motor and amplifier types.
¾ Reduce the accelerations/decelerations.
¾ Check that the axis is not positioned on a mechanical stop.
¾ Check that the value of the parameter Speed following error threshold is compatible with the operation
cycle. If necessary, increase the value of this parameter.
2 - OPERATING PROBLEMS
2.1 - MOTOR DOES NOT MOVE
¾ Check that the amplifier is on (24 VDC auxiliary supply on).
¾ Check that the power supply is on.
¾ Check the motor connection.
¾ Check the logic wiring of the signals FC+, FC- and ENABLE (chapter 8, section 4).
2.2 - MOTOR SUPPLIED, BUT NOT TORQUE
¾ Check that the Maximum current and Rated current parameters have no zero value.
¾ Check that the amplifier is not operating in torque mode (CI command active on X4) with zero input command.
2.3 - SHAFT LOCKED, ERATIC OSCILLATIONS OR ROTATION AT MAXIMUM SPEED
¾ Check the resolver wiring on the X1 connector and the mechanical mounting of the resolver on the motor.
¾ Check the proper motor choice in the MOTOR LIST module.
¾ Check the value of the Motor parameters in the Advanced Functions menu and execute the AUTO-
PHASING command again, with unloaded motor, if necessary (see chapter 6, section 3).
2.4 - DISCONTINUOUS MOTOR ROTATION WITH ZERO TORQUE POSITIONS
¾ Check the connection of the 3 phase cables between motor and amplifier.
2.5 - MOTOR DRIFT WITH ANALOG INPUT COMMAND AT ZERO SPEED
¾ Check that the input command wiring between the controller and the amplifier corresponds to the
recommendations of chapter 4 (CV- at diff. low of the NC and 0 Volt cable).
¾ Check the offset compensation and, if necessary, execute the Offset compensation command.
2.6 - LOUD CRACKLING NOISE IN THE MOTOR AT STANDSTILL
¾ Check that the motor-amplifier-controller ground connections correspond to the recommendations of chapter
4.
¾ Check that the speed input command wiring between controller and amplifier correspond to the
recommendations of chapter 4 and check the shield connection of the resolver cables on motor and amplifier
side.
