Serial Encoder Reading
The drive is receiving position
information from the absolute
incremental encoder. All run
commands are ignored during
this time.
Absolute incremental encoder is
reporting its position by bringing a
multifunction input (A2 or A3) above
9V. Wait for the absolute incremental
encoder to finish homing (35 sec.
max), or troubleshoot analog input
wiring.
