7.13 Motor Module as a Braking Module

7.13 Motor Module as a Braking Module
This function uses a Motor Module as a Braking Module. To do this, three resistors are
connected to the Motor Module instead of a motor.
Requirements for operation as a Braking Module:
● Three identical braking resistors in a star (see table below) or delta connection
● At least 10 m cable length to the resistors
● Configuration in STARTER
– VECTOR drive object
– V/f control
Note
This function is released for:
• SINAMICS S120 Motor Modules Cabinet
• SINAMICS S120 Motor Modules Chassis (500 V - 690 V)
• SINAMICS S120 Motor Modules Chassis (380 V - 480 V) > 250 kW
• SINAMICS S120 Motor Modules Chassis Liquid Cooled (380 V - 480 V) > 250 kW
• SINAMICS S120 Motor Modules Chassis Liquid Cooled (500 V - 690 V)
7.13.1

Features

● Three identical resistors required
● Parallel connection of Motor Modules possible
● Integrated protective devices are available for monitoring the resistors
● The chassis Motor Module must be switched on in order that it can operate as Braking
