CN1A
Outputs the zero-point signal of the encoder. One pulse is
14
output per servo motor revolution. OP and LG are connected
when the zero-point position is reached. ( Negative logic)
Min. pulse width is about 800µs. For zeroing
using this pulse, set the creep speed to 100r/min. or less.
CN1A
Outputs pulses per servo motor revolution set in parameter
6
No. 27 in the differential line driver system. The encoder
CN1A
B-phase pulse lags the encoder A-phase pulse by a phase
angle of π/2.
