Installation and Configuration
Ndrive HPe 50/75/100
2.4.1. Encoder Interface (J207)
The Ndrive HPe 50/75/100 is equipped with standard and auxiliary encoder feedback channels. The
standard encoder interface is accessible through the Motor Feedback (J207) connector. The standard
encoder interface will accept an RS-422 differential line driver signal. If the Ndrive HPe 50/75/100 has been
purchased with the -MXH option, the standard encoder interface can be configured for an analog encoder
input via parameter settings.
Refer to
for encoder feedback phasing. Refer to
for the auxiliary encoder
channel.
N O T E :
Encoder wiring should be physically isolated from motor, AC power, and all other power wiring.
