4.2.12 Manual Pulser Function
A manual pulser is a device to generate pulse trains by hand. The
pulses are sent to the motion controller and re-directed to pulse
output pins. The input pulses can be multiplied or divided before
sending out.
The motion controller receives two kinds of pulse trains from a
manual pulser device: CW/CCW and AB phase. If the AB phase
input mode is selected and the multiplier has the additional selec-
tions of 1, 2, or 4.
The following figure shows a pulser ratio block diagram.
4.2.13 Simultaneous Start Function
Simultaneous motion means more than one axis can be started by
a simultaneous signal which could be external or internal signals.
For external signals, users must set move parameters for all axes
first, then these axes will wait for an external start/stop command
to start or stop. For internal signals, the start command could
come from a software start function. Once it is issued, all axes
which are in waiting synchronous mode will start at the same time.
