Setting Procedure
Connection with Servo Drive
1. Setup of absolute encoder (OMNUC G5/W Series only)
2. Setting of PCU axis parameter
3. Execution of Origin Search
To use an absolute encoder, you must connect the encoder phase A and B inputs from the
Servo Drive to the RUN output and SEN output for the Servo Drive. Also note that, in relation
to the pulse output, you cannot acquire proper absolute data if the forward/reverse direction
connections are wrong.
Connect correctly according to "Connection Examples for OMNUC G5/G-series Servo Drive"
on page 2-40. (To connect to any OMNUC W Series Servo Drive, refer to the wiring diagram
in "Appendix-3 Servo Drive Connecting Cable".)
This section explains the procedure to set the origin of an absolute encoder system.
For the OMNUC G Series, setup of the absolute encoder is not necessary.
For the setup method of the OMNUC G5 Series, refer to User’s Manual for OMNUC G5-series
AC Servomotor/Servo Drive (I571). For the setup method of the OMNUC W Series, refer to
User’s Manual for OMNUC W-series AC Servomotor/Servo Drive (I531).
Select [Encoder Type] under [Feedback Pulse Input Setting] among the PCU axis parameters.
For details, refer to "Feedback Pulse Input Setting" on page 5-43.
Execute Origin Search.
After the origin determination, load the command position after the origin determination, and
the offset of the mechanical origin that was read from the absolute encoder, into the axis
parameter [ABS Encoder Origin Position Offset].
After you set the absolute encoder origin, save the parameters. For information on how to save
data, refer to "Saving Data" on page 8-42.
