FP2 Positioning Unit Deceleration Stop and Forced Stop
12-7
12.4 Precautions Concerning Stopping Operations
12.4.1 Pulse Output Done Flag Status After a Stop
For either a deceleration stop or a forced stop, the pulse output done flag goes ON after operation has
stopped. If the pulse output done flag is being used as a trigger signal for operation after positioning has
been completed, the program should be set up so that operation does not proceed to the next step
following a deceleration stop or a forced stop.
12.4.2 Restarting After a Stop
When a deceleration stop or forced stop is triggered, the start flags for all operations must be turned
OFF before operation can be restarted. This operation is common to E point control, P point control,
home return, JOG operation, JOG positioning operation and pulser input operation.
12.4.3 Forced Stop Elapsed Value Data
Elapsed value data in the shared memory is saved after a forced stop is applied. Under normal
conditions, it is possible that a mechanical error has occurred, so after home return, we recommend
positioning control start.
