7.5.1 Introduction
A brake control option module (Safe Brake Relay) is required for operating motors with
holding brakes.
The brake control option module is the electrical interface between the CU/PM340 and the
brake of a motor.
This is mounted in the Screening Kit (refer to the Chapter "Screening Kit") or alternatively at
the rear cabinet panel.
7.5.2 Safe Brake Relay
The Safe Brake Relay can be used in conjunction with Power Modules in blocksize format to
control a 24 V DC motor brake.
The brake is electronically controlled. All holding brakes can be used up to 2 A. To operate
the brake, it is necessary to connect the supply voltage for the brake separately at the brake
control option module. In this case, a regulated power supply is required whose rated value
(to balance the voltage drop in the supply cable for the 24 V DC motor brake coil) can be set
to 26V (e.g. SITOP modular).
