Technical Data
10.4 Brake
The mechanical brake is a holding brake implemented as a spring-loaded brake.
The brake has a standard supply voltage of DC 24 V and operates with 1 or 2 braking
torque ratings for each motor size (CMP40, CMP50 and CMP63).
The brake cannot be retrofitted and operates without brake rectifier or brake control unit.
If the servomotors are run on inverters from SEW-EURODRIVE, overvoltage protection
is provided.
If the servomotors are run on non-SEW-inverters, overvoltage protection must be imple-
mented by the customers themselves using, for example, varistors.
Observe the notes in the relevant operating instructions for servo controllers concerning
the switching sequence of motor enable and brake control during standard operation.
