The PLC Tools SIM-S24 Servo Simulator 24VDC User Manual was developed to assist integrators in application development for projects with analog servo drives and incremental encoder feedback.

It allows motion application debugging in the lab environment, virtually on the table, with PLC or CNC only and without actual running motors and drives. This reduces installation time from weeks to hours.

Servo simulator uses an advanced microcontroller that allows high-speed move simulation and fast response.

This updated version adds selectable deadband for open loop control systems.
