8.3 Operation with spring-applied brake
8.3.1 Introduction
Lenze three-phase AC motors and G-motion geared motors can be equipped with
spring-applied brakes (motor holding brakes). An external motor brake control module is
required for switching and as a DC supply of the spring-applied brakes.
The suitable motor brake control module is selected according to the rated data of the
spring-applied brakes.
Controllers in the HighLine C/TopLine C version offer an integrated control for brakes with
24 V connection and a braking current of up to 2.5 A.
Switching the brake
For controllers of the StateLine C, HighLine C, and TopLine C versions, the switching
operation of the brake can be controlled:
ƒ Via an external control contact (e.g. PLC)
ƒ Via a brake switch which is connected to one of the digital outputs of the controller.
The digital output must be parameterised accordingly.
For controllers of the HighLine C and TopLine C version, the switching operation of the
brake can be controlled additionally:
ƒ Via an integrated brake control
The software manual contains further information on the parameterisation and the
integrated brake management.

Stop!
The integrated brake control includes an electronic switch which can control a
24V motor holding brake.
Only motor holding brakes which comply with the permissible data mentioned
in the Technical Data may be connected to the integrated brake control. (If
necessary, the holding brake must be controlled without a brake control via a
digital output and a coupling relay.)
If the permissible values mentioned in the Technical Data are not observed:
ƒ the brake control may be destroyed.
ƒ a safe operation of the motor holding brake is not ensured.
Observe additional notes in the documentation of the standard device!
