Example 2: Exceeding
CW or CCW Limit
The emergency stop flag is not affected by exceeding the CW or CCW limit.
When a limit is exceeded, only pulse output in the opposite direction is possi-
ble. In other words, when the CW limit is exceeded, only CCW pulse output is
possible. Although a CCW HIGH-SPEED JOG is used to clear the CW limit
flag in the example, LOW-SPEED JOG or ORIGIN SEARCH may also be
used.
