Installation and Configuration

2.3.1. Encoder Interface (J104)

The Ensemble CL is equipped with standard and auxiliary encoder feedback channels. The standard
encoder interface is accessible through the Motor Feedback (J104) connector. The standard encoder
interface will accept an RS-422 differential line driver signal. If the Ensemble CL has been purchased with
the -MXU option, the standard encoder interface can optionally be configured for an analog encoder input via
parameter settings.
Refer to Section 2.3.1.5.
channel.
N O T E : Encoder wiring should be physically isolated from motor, AC power, and all other power wiring.
N O T E : The PSO feature is not compatible with the -MXU option. The PSO feature operates with the -
MXH option and with square wave encoders.
