“
The
”command pulse input multiplier
signal is a universal configurable switch input, see
for wiring details.
Note
●
When the input pulse frequency is too low and the Pn203 setting is too large, unstable speed
may occur.
●
Switch the command pulse multiplier when the position command pulse is 0. If you switch when
the position command pulse is not 0, the servo motor may cause position deviation or position loss.
