The jog increment is too large or too small.

Cause:

1. During continuous jogging, the jog speed is directly switched to incremental jogging.
2. Software defect.

Troubleshooting:

Check whether the speed was directly switched to incremental jog speed during continuous jogging.

Solution:

1. Pause jogging, then switch the speed to incremental jogging mode to jog.
2. Contact after-sales personnel, copy all files from the controller's ftp, and send them to after-sales personnel.

Case sharing:

None.
