the servo amplifier, and then connect the wire from the servo amplifier to the ground via the protective earth
of the cabinet. Do not connect the wire directly to the protective earth of the cabinet.
To avoid a malfunction, connect the wires to the correct phase terminals (U, V,
and W) of the servo amplifier and servo motor.
Do not connect AC power supply directly to the servo motor. Otherwise, it may
cause a malfunction.
Do not use the 24 V DC interface power supply for the electromagnetic brake.
Always use the power supply designed exclusively for the electromagnetic brake.
Otherwise, it may cause a malfunction.
