5.2 Interfaces

In order to operate the CMMS-ST stepping motor controller a 24 V-power source to supply
the electronics systems. It is connected to terminals +24 V and 0 V.
The supply voltage for the power output stage is connected to contacts ZK+ and 0 V.
The motor is connected with the four terminals A ... B/. The motor temperature sensor is
connected to the TEMP+ and TEMP- terminals (PTC, SI sensor or N/C contact). KTY81 ...
KTY84 can be used as analogue temperature sensors.
The connection of the optional shaft encoder via the d-sub plug to [X2] is illustrated in the
F ig. 5.4 diagram.

The CMMS-ST stepping motor controller must first be fully wired. Only then can the opera-
ting voltages be activated for the intermediate circuit and the power supply. If the polarity
of the operating voltage connections is reversed, or if the operating voltage is too high or
the operating voltage and motor connections are incorrectly connected, the CMMS-ST
stepping motor controller will be damaged.

5.3 CMMS-ST complete system

A complete CMMS-ST stepping motor controller system is shown in
components are required to operate the stepping motor controller:
