The source of general purpose counter could be any of the follow-
ing:
1. Command position output – the same as a command
position counter
2. Feedback position input – the same as a feedback posi-
tion counter

Target position recorder
The target position recorder is used for providing target position
information. It is used in continuous motion because motion con-
troller need to know the previous motion command’s target posi-
tion and current motion command’s target position in order to
calculate relative pulses of current command then send results
into pre-register. Please check if the target position is the same
with current command position before continuous motion; espe-
cially after the home and stop functions.
