XC2 Hardware Manual
Chapter 2: Installation and Configuration
2.3.1. Encoder Interface
The standard encoder channel is accessible through the Feedback connector. The PositionFeedbackType or
VelocityFeedbackType parameters configure the XC2 to accept RS-422 differential line driver signals
(
), or, as permitted by the multiplier option,
analog signals (
).
There are two multiplier options (consult your order information to determine which option your XC2 has been
configured with):
-MX0: This option allows the XC2 to accept RS-422 or absolute encoder signals.
-MX1: This option allows the XC2 to accept analog signals in addition to RS-422 and absolute
encoder signals.
Refer to
for encoder feedback phasing.
Refer to
for the auxiliary encoder channel on the AUX connector.
NOTE:
Physically isolate the encoder wiring from motor, AC power, and all other power wiring
