Phase Signal Output (P.o) - Melec GDB-5K40 Instruction Manual

(4) Phase signal output（P.O）
① Output current
● In case of the excitation home position, the signal is output.
(photo-coupler ON)
● In case of simultaneously using P.O signal and C.S signal,
input C.S signal while P.O signal is being output to switch the step angle.
Otherwise, P.O signal may not be output.
