-SG are disconnected when power is switched off or the
protective circuit is activated to shut off the base circuit. Without
alarm, ALM
-SG are connected within about 3s after power on.

-SG are connected when the number of droop pulses is in the
preset in-position range. The in-position range can be changed using
DRU parameter No. 5.
When the in-position range is increased, INP
-SG may be kept
connected during low-speed rotation.

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 minimum pulse width is about 400
s. For home position return
using this pulse, set the creep speed to 100r/min. or less.
