Refer to Section "Digital inputs/outputs (DIs/DOs) (Page 91)" for detailed information about
the digital outputs.
Connection example (for V90 200 V variant only)
The following shows the example when the brake is controlled through the motor holding
brake signal (Brake) of the SINAMICS V90 200 V variant servo drive.
Note
It is the Isolated digital output power supply. When you use the 24 VDC power supply, it
1)
can be also the controller power supply.
The motor brake can be controlled not only by the brake control signal from the SINAMICS
2)
V90 servo drive but also by external emergency stop.
Never use the same power supply for the brake (24 VDC) and for the brake control signal
3)
(P24 V).
Install a surge absorber as the above figure shows to suppress surge voltage generated by
4)
ON/OFF action of the relay (RY). When you use a diode, the time from the brake release to
brake engagement is slower than the case when you use a surge absorber.
