3.8 Connection of servo amplifier and servo motor

3.8.1 Connection instructions

WARNING
CAUTION
The connection method differs according to the series and capacity of the servo motor and whether or not
the servo motor has the electromagnetic brake. Perform wiring in accordance with this section.
(1) For grounding, connect the earth cable of the servo motor to the protective earth (PE) terminal of the
servo amplifier and connect the ground cable of the servo amplifier to the earth via the protective
earth of the control box. Do not connect them directly to the protective earth of the control panel.
(2) Do not share the 24VDC interface power supply between the interface and electromagnetic brake.
Always use the power supply designed exclusively for the electromagnetic brake.

3.8.2 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 required for wiring, refer to Section 13.2.1. For
encoder cable connection, refer to Section 13.1.5. For the signal layouts of the connectors, refer to Section
3.8.3.
For the servo motor connector, refer to Chapter 3 of the Servo Motor Instruction Manual.
Insulate the connections of the power supply terminals to prevent an electric
shock.
Connect the wires to the correct phase terminals (U, V, W) of the servo amplifier
and servo motor. Otherwise, the servo motor will operate improperly.
Do not connect AC power supply directly to the servo motor. Otherwise, a fault
may occur.
POINT
Do not apply the test lead bars or like of a tester directly to the pins of the
connectors supplied with the servo motor. Doing so will deform the pins,
causing poor contact.
