Motor Module As A Braking Module - Siemens SINAMICS S120 Function Manual

8.14

Motor Module as a Braking Module

Overview
You can parameterize this function in the STARTER commissioning tool.
Requirement
● Three identical braking resistors in a star (see table below) or delta connection
● At least 10 m cable length to the resistors
● Configuration in the STARTER commissioning tool
– Drive object vector
– U/f control
Function description
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.
Supported Motor Modules
The function is released for the following Motor Modules:
● 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)
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
Module.
