Relevant parameters
Parameter
p1215
p1216
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 control word
STW1.0 has a rising edge and becomes closed once the motor is in "servo off" state.
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. 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 servo drive.
Note
For 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
