Terminal box on servo motors AC3 and AC4
To supply the voltage to the servo motor (see Fig. 7-9) via the servo amplifier you will
need a cable with a layout as shown in Fig. 7-10.
INFORMATION
Please note that the thermal switch connection is only available via the motor feedback
cable (see sections entitled “Resolver” and “Hiperface rotary encoder”).
Cable features:
• Cable cross section: max. 14 mm
- Wires for supply voltage: max. 3 x 2.5 mm
2
- Wire for earth conductor PE: max. 1 x 2.5 mm
2
- Wires for holding brake: max. 2 x 1 mm
