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
FSP Servo System Catalog (YEA-KAA-FSP-6).
