Protection And Monitoring Functions Of Internal Components; Protection And Monitoring Functions For External Components; Control Module - Siemens SINAMICS SM120 Operating Instructions Manual

Description

3.2 Control Module

3.1.3

Protection and monitoring functions of internal components

The internal components of the drive have the following protection and monitoring functions:
● Drive protection based on monitoring systems:
● Shutdown in the event of semiconductor failure
● Shutdown in the event of control component failure
● Internal protection functions for the control hardware
● Protection against communication failure between the closed-loop control and the power
● Anti-condensation heating
3.1.4

Protection and monitoring functions for external components

Transformer and motor can be monitored in the drive. A fast protective shutdown that you can
activate for external problems, e.g. short-circuits, is present.
3.2 Control Module
The purpose of the Control Module is for the open-loop and closed-loop control of the drive.
Operating control and diagnostics of the drive are also realized using the Control Module.
Note
Details on the design can be found in the layout diagram.
