3.5 Wiring Encoders (for SGMGH and SGMSH Motors Only)
The following sections describe the procedure for wiring a servo amplifier to the encoder.
3.5.1 Encoder Connections
The following diagrams show the wiring of the encoder output from the motor to
CN2 of the servo amplifier, and PG output signals from CN1 to the controller. This
applies to both incremental and absolute encoders of SGMGH and SGMSH motors
only. The numbers in parentheses ( ) are applicable to SGMAH motors. For SGMPH
motors, refer to the Sigma II Servo System Product Catalog Supplement.
