11.2.10 Stopping Methods
If the /HWBB1 or /HWBB2 signal turns OFF and the HWBB operates, the Servomotor will stop
according to the stop mode that is set for stopping the Servomotor when the servo turns OFF
(Pn001 = n.
X). However, if the dynamic brake is enabled (Pn001 = n.
0 or
n.
1), observe the following precautions.
11.2.11 ALM (Servo Alarm) Signal
The ALM (Servo Alarm) signal is not output in the HWBB state.
CAUTION
The dynamic brake is not a safety-related element. You must design the system so that a
hazardous condition does not occur even if the Servomotor coasts to a stop in the HWBB
state. Normally, we recommend that you use a sequence that returns to the HWBB state
after stopping for a reference.
If the application frequently uses the HWBB, stopping with the dynamic brake may result in
the deterioration of elements in the SERVOPACK. To prevent internal elements from deterio-
rating, use a sequence in which the HWBB state is returned to after the Servomotor has
come to a stop.
