2.5.6 Connection of servo amplifier and linear servo motor
(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 linear servo motor. Otherwise, the linear servo motor will operate improperly.
Do not connect AC power supply directly to the linear servo motor. Otherwise, a
fault may occur.
POINT
Refer to Section 11.1 for the selection of the encoder cable.
For grounding, connect the earth cable of the linear 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.
