Forcing The Motor To Stop; Fstp (Forced Stop Input) Signal; Stopping Method Selection For Forced Stops - YASKAWA SGD7S Product Manual

6.13 Forcing the Motor to Stop

6.13.1 FSTP (Forced Stop Input) Signal

6.13 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).

Input
Note: You must allocate the FSTP signal to use it. Use Pn516 = n.X (FSTP (Forced Stop Input) Signal Alloca-
tion) to allocate the FSTP signal to a connector pin. Refer to the following section for details.

6.13.2 Stopping Method Selection for Forced Stops

Use Pn00A = n.X (Stopping Method for Forced Stops) to set the stopping method for
forced stops.
Pn00A
Note: You cannot decelerate a Servomotor to a stop during torque control. For torque control, the Servomotor will
be stopped with the dynamic braking or coast to a stop according to the setting of Pn001 = n.X (Motor
Stopping Method for Servo OFF and Group 1 Alarms).

Panel Operator and Digital Operator Displays
When a forced stop is performed, the panel and the Digital Operator will display FSTP.
 To prevent accidents that may result from contact faults or disconnections, use a normally
closed switch for the Forced Stop Input signal.
Signal Connector Pin No.
FSTP Must be allocated.
