Outputs the zero-point signal of the encoder. One pulse is output
per servo motor revolution. OP and LG are connected when the
zero-point position
is reached. (Negative logic)
The maximum pulse width
is about 4OOp. For zeroing using this
pulse,
set the creep speed to 100r/min. or less.
Outputs pulses
per servo motor revolution set in parameter No.
27 in the differential line driver system. The encoder B-phase
pulse
lags the encoder A-phase pulse by a phase angle of d2.
The same signal aa OP is output in the diEferential line driver
system.
