Solution

The actual motor speed does not correspond to speed reference.

Preset speeds configuration interferes with speed reference from controller.

Disable preset speeds in application functions setting of the drive.

The actual motor speed does not correspond to speed reference.

Limit switch configuration interferes with speed reference from controller.

Disable limit switch function in application functions setting of the drive.

The actual motor speed or read actual speed do not correspond to speed reference.

PDO mapping is inconsistent.

Make sure that both speed reference and actual speed values have the same unit (Hz or RPM).

q_xAlrm of the FB is TRUE.

One or more of the input parameters are out of range.

Verify that the input parameters are within the specified range.

FB generates a correct speed profile, but the actual motor speed lags behind the speed reference, quality of Anti-sway is low.

Acceleration and deceleration ramps inside the drive are not set to 0.1 s.

Set the ramps in drive to 0.1 s.

Speed profile is generated and followed by the motor, but the quality of Anti-sway is low.

Some of the input parameters are incorrect.

Check the cable length and maximum linear speed parameters.
