The counter will increment every time a pulse is received. The count can be read using the PI query. In
order to reset the counter de-configure capture mode to disabled and then back to pulse count.
The capture mode can be selected using the PC Configuration Utility.
The captured signals are then adjusted and can be used as command or feedback accord-
ing to the processing chain described in the diagram below.

Except for the capture, all other steps are identical to those described for the Analog cap-
ture mode.
Use of Pulse Input
After the pulse input has been fully processed, it can be used as a motor command or,
if the controller is configured to operate in a closed loop, as a feedback value (typically
speed or position).
Each input can therefore be configured to be used as command or feedback for any motor
channel(s). The mode and channel(s) to which the analog input applies are selected using
the PC Configuration Utility.
