3-2-2 Connection diagram
The following table lists wiring methods according to the servo motor types. Use
the connection diagram which conforms to the servo motor used. For cables re-
quired for wiring, refer to Section 6-2-1.
For encoder cable connection, refer to Section 6-1-2.
For the connectors of the servo motor, refer to Chapter 3 of the servo motor
instruction manual.

Note: 1. To prevent an electric shock, always connect the protective earth (PE) terminal of the servo amplifier to the
protective earth (PE) of the control box.
2. This circuit applies to the servo motor with electromagnetic brake.
3. For the HA-FF series, connect the ground cable to the earth terminal of the servo motor.
