malfunction or faulty may occur.
3.10.1 Connection instructions
WARNING
Insulate the connections of the power supply terminals to prevent an electric
shock.
CAUTION
Connect the wires to the correct phase terminals (U, V, W) of the servo amplifier
and servo motor. Not doing so may cause unexpected operation.
Do not connect AC power supply directly to the servo motor. Otherwise, a fault
may occur.
POINT
Refer to section 11.1 for the selection of the encoder cable.
This section indicates the connection of the servo motor power (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.
