8.4.35 Engaging and disengaging the motor brake
COMPAX controls the idle holding brake of the motor and final stage. The time
behaviour can be set using P17 and P211 Bit 2.
If you are using an axis which is under torque when idle (e.g. when using a z axis),
the drive can be engaged and disengaged in a manner which ensures that the load
does not move. To do this, the drive remains powered during the reaction time of
the idle holding brake. This can be set using P17 (see following diagrams).
Final stage blocked by:
♦ error or
♦ OUTPUT O0="1" or
♦ emergency STOP.
The final stage is enabled via:
♦ quit or
♦ OUTPUT O0="0" or
♦ once Power is on
with P211 Bit 2="0".
The final stage is enabled
via:
♦ OUTPUT O0="0"
P211 Bit 2="1"
(the lag of 0.5s is switched off)
