Use SEN to BAT (-) signals for absolute encoders. See 5.7 Absolute Encoders for
more details.
SG: Connect to 0V on the host controller.
Pulse Divider Setting
Set the pulse dividing ratio in the following parameter.
Set the number of pulses for PG output signals (PAO, /PAO, PBO, /PBO).

• When using the servo amplifier phase C pulse signal to return to the machine origin, always turn the
servomotor at least twice before starting the original return operation.
If the configuration of the mechanical system prevents turning the servomotor before the origin return
operation, then perform the origin return operation at a servomotor speed of 600rpm or below. The phase C
pulse signal may not be correctly applied if the servomotor turns faster than 600rpm.
