The 1394 GMC System and S Class Compact motion controller have
an encoder loss circuit that detects when the encoder drivers are
disabled. When the REC faults:
• The REC disables the encoder drivers.
• The REC signals an encoder loss fault ot the controller.
Important: The Transducer Loss Detection feature is an option in
the Edit Axis window in GML. We recommend that you
keep the transducer loss detection feature enabled in the
motion controller. Consult your motion controller’s
Installation and Setup Manual/User Manual and GML
Programming Manual for more information about how to
apply this feature.
