Terminating Jogging
The “jogging” mode is terminated in the following situations:
• When you release the “jogging” button (DIR_M or DIR_P=0)
• When the FM 351 receives a STOP signal (STOP=1)
• When the actual value of a synchronized linear axis reaches the limit of the
working range. Travel is then only possible in the opposite direction.
After terminating the positioning operation, travel can be continued in either
direction.
Aborting Jogging
The “jogging” mode is aborted in the following situations:
• The drive enable signal is cleared (DRV_EN=0)
• A travel range limit is passed on a linear axis.
