POSITIONING MODULE FOR SIMATIC S7-200 PLC

The EM 253 is a positioning expansion module for the Simatic S7-200 PLC for precise control of microsteppers and intelligent servo drives. A separate controller independently of the main CPU handles positioning tasks.

The module outputs directional-response-path and speed information to the PLC's power section over an integrated pulse-train interface. It is also equipped with signal inputs for direct position sensing via position switches. Positioning tasks are configured using a graphics-supported assistant in Micro/WIN, which also generates the control commands for the user's program. All parameters for the positioning EM are stored on the CPU It is possible to store as many as 25 positioning profiles, which can then be called in the user program when needed.
