POINT
(Note-1): The rapid stop command and emergency stop from a peripheral
device are valid during deceleration due to input of an external
STOP signal or the stop command (M3200
+
20n), and processing
according to the rapid stop deceleration time parameter starts at the
time the stop condition occurs.

[Cautions]
(1) After running speed control using the absolute data system, the feed current
value cannot be set to zero by the following operations:
•
Reset with the RUN key
•
Turning on the servo power supply (OFF
→
ON)
(2) The dwell time cannot be set.
