OP
CN1A
14
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 400
µ
s. For zeroing using this
pulse, set the creep speed to 100r/min. or less.
