Motor Power Cable
For use of motor power cables, please abide by the followings.
• Servo motors must be connected to grounding, otherwise it may cause electrocution. For
grounding method, see "4-8 Remedying Noise and High Harmonics", page 4-41.
• In order to prevent the danger from movement of movable part of servo amplifiers when the
power is OFF, which is caused by the dead weight of movable part of servo amplifiers or external
forces on them, motor with electromagnetic brake can be used sometimes. When motor with
electromagnetic brake is used, see "Electromagnetic Brake", Page 4-17.
• The wiring between servo motor and servo amplifier must be connected correctly according to
terminal name (U, V, W). Otherwise the servo motor will be abnormal.
