200 kHz open-loop positioning expansion module for compatible stepper motor or servo-drive axes.
Siemens 6ES7253-1AA22-0XA0 is the SIMATIC S7-200 EM 253 positioning expansion module. Siemens specifies the unit for 200 kHz open-loop control of stepper motors or servo drives, with configuration and programming through STEP 7-Micro/WIN.
The module provides five dedicated digital inputs for stop, reference-point, positive-limit, negative-limit and zero-point functions. Four drive-interface signals can be used with RS 422/485 or 5 V DC signaling, supporting pulse-based positioning in legacy S7-200 machine-control installations.
