3. SIGNALS AND WIRING
3.6Connection of servo amplifier and servo motor 3.6.1 Connection instructions
WARNING | 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
CAUTION 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.
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.
