5.4 Electrical Installation
Two different connection types define the function of the TM StepDrive module:
5.4.1 Connection Type
“Power stage“
Connect the motor voltage (24 to 48 V
DC
) to terminals L+ and M
Connect the stepper motor to the terminals A, B, C, D

The following applies for connecting the motor voltage at terminals L+ and M:
An internal protection circuit protects the technology module from damage due to
reverse polarity of the supply voltage.

If the +24 V
DC
input is additionally supplied with voltage in this connection type,
the CLK, DIR and RUN outputs are also active. In this way, an external power
stage can be controlled by the indexer in addition to the integrated power stage.
The limit switches are optional.
