For switching between positive and negative logic of the pulse, "Switch 1" is used.
The following shows the examples of each pulse output mode.
1) CW/CCW mode
During forward run, the forward run feed pulse (CW) is output.
During reverse run, the reverse run feed pulse (CCW) is output.
Positive logic
Reverse run
* CW is output from the "PULSE F" external I/O signal and CCW from "PULSE R". (Refer to "Section
