SINAMICS S120 Fail-Safe Drives

Description

For drive_2 set the following:

Bit0: Control Unit DI1

Bit1: TM54F F-DI2

Bit2: 0

Bit3: Control Unit DI3

Fixed value 1 : 33 rpm

Fixed value 3 : 333 rpm

Fixed value 9 : 666 rpm

Fixed value 11 : 666 rpm

Explanation: If the "SLS_door2"

signal is active (in the dia-

gram: "High"), then a change-

over is made from a high

speed (setpoint) to a low

speed (setpoint).

By pressing –S8, independent of

the state of the safety door, a

fixed speed of n=666 rpm is

entered.

Save the project and compile.

Go online.

Download the project into the

target device (e.g. PLC) and copy

RAM to ROM.

You can now operate the drives

(without safety functions).

This is realized with a positive

signal edge at DI1.
