Axis I/O Port Encoder Input

The Axis I/O Port provides an input for a differential incremental encoder. The encoder
output signals from the drive should be connected to the Axis I/O Port encoder input
for each axis. The Axis I/O Port encoder input accepts RS422 differential inputs. The
encoder signals should be quadrature type. All encoder wiring between the MMC and
the drive should be shielded twisted pair as shown in
For more information on the Encoder input operation, refer to
of Appendix
The power supply that powers the encoder must be referenced to the power
supply that powers the MMC. This is done by connecting the "common" ter-
minal of each supply back to Single Point Ground. Failure to observe this pre-
caution may result in sporadic encoder operation and/or damage to the
MMC.
