7.4 Handling the STOP command
2. STOP command during positioning operation (without the JOG operation, manual pulse
generator operation or variable speed operation)
When the STOP command is turned ON during positioning control operation, the operation is as follows
according to the stop mode setting. There are two types of stop mode: the positioning control end mode and
remaining travel distance operation mode.
1) Positioning control end mode
When the STOP command is turned ON, operation decelerates to a stop and is terminated.
When the STOP command is OFF, positioning operation begins when the START command is turned
ON.
2) Remaining travel distance operation mode
When the STOP command is turned ON, operation decelerates to a stop and the 20SSC-H enters
standby state for the remaining travel distance operation. At this time, "standby for remaining travel
distance" flag is turned ON. When the STOP command is OFF and the START command is turned ON
during standby status, positioning operation continues for the remaining travel distance.
