1.2
Forcing the Motor to Stop
You can force the Servomotor to stop for a signal from the host controller or an external device.
To force the motor to stop, you must allocate the FSTP (Forced Stop Input) signal in Pn516 =
n.
X. You can specify one of the following stopping methods: dynamic brake (DB), coast-
ing to a stop, or decelerating to a stop.
Note: Forcing the motor to stop is not designed to comply with any safety standard. In this respect, it is different
from the hard wire base block (HWBB).
This functionality is supported by the following SERVOPACKs.
