30 Signal Connections
3.2 Encoder Feedback Input Signal
The AMP-304C provides 4 encoder feedback input channels each
with up to 4MHz and EA, EB, and EZ signals. Each group of EA,
EB, and EZ signals contains a pair of differential signals (e.g. the
EA signal contains EA+ and EA-).
A 32-bit counter for each encoder feedback input axis and two
kinds of decoder modes (CW/CCW, 1x/2x/4x AB Phase) are avail-
able. For more information, see the APS Function Library User
Manual.
