p1217
You can configure the holding brake with the parameter p1215 according to the actual
application. When you set p1215=1, the motor holding brake is open once the digital input
signal SON has a rising edge and becomes closed once a falling edge comes to SON.
If the servo motor is used to control a vertical axis, the machine movable part can have a
slight shift when the holding brake becomes open or closed simultaneously with the action of
SON. To eliminate such slight shift, you can configure a delay time for the close or open time
of the motor holding brake by setting the parameters p1216 and p1217.
Note
The default values of p1216 and p1217 depend on the rated power of the motor which
connects to the SINAMICS V90 servo drive.
Note
For SINAMICS V90 200 V variant servo drives, the actual motor holding brake time consists
of the time delay of the motor brake and the time delay of the current amplifying component
(a relay in the example above); therefore, you can set the values of p1216 and p1217 as
follows:
p1216 = motor brake opening time + relay opening time
p1217 = motor brake closing time + relay closing time
