Employing a Rod Lock with a PCS System

in a Linear Motion Control System

Programming Requirements for Using the Rod Lock with a PCS Control

The PCS control has a digital (@Position) signal to indicate when the cylinder its at its

commanded position (actually within +/- the deadband setting of its commanded position). If the

rod is in motion and is about to overshoot the target, one could inadvertently engage the Rod

Clamp, causing it to act as a dynamic brake. It is therefore necessary to monitor the @Position

signal before engaging the Rod Lock to be certain that the payload is within the deadband zone
