| The EM 253 is a function module for simple positioning tasks (1
axis). It can be connected to stepper motors and servo motors from the Micro
Stepper to the high-performance servo drive via a high-frequency pulse input The EM 253 positioning module is mounted in the same manner as an
expansion module and connected to the S7-200 expansion bus via the
integrated connection cable.
The configuration data are read out of the CPU automatically on
connection.
