Output Phase Form
Use SEN to BAT (-) signals for absolute encoders. See 4.7 Absolute Encoders for more
details.
SG: Connect to 0 V on the host controller.
When using the SERVOPACK phase-C pulse signal to return to the machine origin, always turn the
servomotor at least twice before starting the zero point return operation.
If the configuration of the mechanical system prevents turning the servomotor before the zero point
return operation, then perform the zero point return operation at a servomotor speed of 600 min -1 or
below.The phase-C pulse signal may not be correctly output if the servomotor is turned faster than
600 min -1 .
