Assembly and installation
Plugs Pin Designation Value Description
8 0V 0 V Reference potential for auxiliary supply voltage.
7 24V +24 V DC Auxiliary supply voltage (from the 24 V DC logic
supply of the motor controller).
6 C2 – Feedback contact for the “STO” status on an
external controller.
5 C1
4 0V-B 0 V Reference potential for STO-B.
3 STO-B 0 V / 24 V Control input B for the STO function.
2 0V-A 0 V Reference potential for STO-A.
1 STO-A 0 V / 24 V Control input A for the STO function.
Tab. 9: Pin allocation [X40] (diagram of the plug on the device)
The STO-A and STO-B control inputs must be connected in parallel over two channels to ensure the
STO “Safe Torque Off” function
è 4.3.1 Safe Torque Off (STO), è Fig. 6.
For example, this interface can be part of an emergency stop circuit or a safety door installation.
4.2.3 Minimum wiring for initial start-up [X40]
For initial commissioning of the motor controller without safety engineering, the motor controller
CMMP-AS-…-M0 can be wired with a minimum circuit in accordance with
è Fig. 6 with an emergency
stop switch ([2]).
NOTICE
Safety functions must never be bypassed.
Install the minimum circuits for the STO-A/STO-B and 0V-A/0V-B inputs for initial commissioning in
such a way that they must be removed when the final safety circuitry is installed.
