Installation and Configuration
Ensemble CP
2.3.1. Encoder Interface (J103)
The Ensemble CP is equipped with standard and auxiliary encoder feedback channels. The standard
encoder interface is accessible through the Motor Feedback (J103) connector. The standard encoder
interface will accept an RS-422 differential line driver signal. If the Ensemble CP has been purchased with
the -MXU option, the standard encoder interface can be configured for an analog encoder input via parameter
settings.
Refer to
Section 2.3.1.5.
for encoder feedback phasing. Refer to
Section 2.5.
for the auxiliary encoder
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.
