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 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 in StateLine and HighLine versions, the switching operation of the brake can
be controlled:
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.
ƒ
The digital output must be parameterised accordingly.
For controllers in the HighLine version the switching operation of the brake can be
controlled additionally:
Via an integrated brake control
ƒ
The software manual contains further information on the parameterisation and the
integrated brake management.
