4.1.11 Manual Pulser Mode
For manual operation of a device, you may use a manual pulser such as a
rotary encoder. The PPCI7443 can input signals from the pulser and output
corresponding pulses from the OUT and DIR pins, thereby allowing you to
simplify the external circuit and control the present position of axis. This
mode is effective when a _7443_pulser_vmove(), _7443_pulser_pmove()
or _7443_pulser_home_move() command has been called. To stop, by a
_7443_sd_stop() or_7443_emg_stop() command or till satisfaction of
movement.
The PPCI7443 receives plus and minus pulses (CW/CCW) or 90 degrees
phase difference signals(AB phase) from the pulser at PA and PB pins. To
set the input signal modes of pulser, use _7443_set_pulser_iptmode()
function. The 90
°
phase difference signals can be input through
multiplication by 1, 2 or 4. If the AB phase input mode is selected, the PA
and PB signals should be with 90
°
phase shifted, and the position counting
is increasing when the PA signal is leading the PB signal by 90
°
phase.

4.1.12 Timer Mode
In this mode, user can delay the execution of program by a specified delay
time (msec).
For example._7443_delay_time (0, 100); after executing this command,
there will be 100 msec delay before executing next command.It is the
