Siemens SIRIUS M200D Manual page 37

Depending on the order variant, the following externally supplied brake coils can be
controlled:
● 400 V AC/230 V AC
(The brake rectifier must be installed in the motor. The rectifier input is controlled via the
motor starter).
● 180 V DC
(A rectifier is not required for the brake in the motor because the motor starter provides
the 180 V DC. In this way, brake coils for 180 V DC can be switched directly.)
The brake voltage is fed to the motor together with the motor infeed via a joint cable. For
more information about connecting the brake output, see Brake output (Page 102).
Note
With both brake output versions, the electronic switching element is located on the AC side.
Please refer to the technical data of the brake (e.g. Catalog D87.1 "SIEMENS MOTOX
Geared Motors") for the resulting application time of the brake.
If faster brake application times are required (DC side tripping), a 400 V / 230 V AC brake
output in conjunction with a function rectifier integrated into the motor is preferable.
Devices with a 180 V DC brake output as of product version E10 are suitable for achieving
fast brake engaging times. This means that the time until the motor comes to a standstill is
shorter compared with previous product versions.
The integrated freewheeling diode is deactivated when switching off the brake output and the
energy of the brake coil dissipated through a varistor.
Brake release delay on starting
Note
Only active if an ON switching command is present for the brake and the motor
simultaneously.
Positive times: Delayed switch-on of the brake output compared to the motor.
Negative times: Delayed switch-on of the motor compared to the brake output.
During a reversing operation, the release delay does not begin until the lock-out time has
expired.
