WARNING
CAUTION
This section indicates the connection of the motor power supply (U, V, W). Use of the optional cable and
connector set is recommended for connection between the servo amplifier and servo motor. When the options
are not available, use the recommended products. Refer to Section 11.1 for details of the options.
(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.
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.
