24-V Open-collector Input
for Command Pulse
Input terminals for position command pulses.
These are selected by setting the Command Pulse Input
Selection (Pn40) to 0.
Line-Driver input:
Maximum response frequency: 500 kpps
Open-collector input:
Maximum response frequency: 200 kpps
Any of the following can be selected by using the Pn42 set-
ting: reverse and forward pulses (CW/CCW), feed pulse
and direction signal (PULS/SIGN), 90
° phase difference
(phase A/B) signals (FA/FB).
