4. CONNECTION OF SERVO AMPLIFIER AND SERVO MOTOR
WARNING
Any person who is involved in wiring should be fully competent to do the work.
Ground the servo motor securely.
Do not attempt to wire the servo motor until it has been mounted. Otherwise, it
may cause an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it
may cause an electric shock.
To avoid an electric shock, insulate the connections of the power supply
terminals.
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may
operate unexpectedly, resulting in injury.
Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may
occur.
Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur.
Do not install a power capacitor, surge killer or radio noise filter (FR-BIF(-H)
option) with the power line of the servo motor.
Do not modify the equipment.
Connect the servo amplifier (converter unit) power output (U/V/W) to the servo
motor power input (U/V/W) directly. Do not let a magnetic contactor, etc.
intervene. Otherwise, it may cause a malfunction.

Before wiring, switch operation, etc., eliminate static electricity. Otherwise, it may
cause a malfunction.
POINT
We recommend using HIV wires to connect the servo amplifier (converter unit)
to the servo motor. Therefore, recommended wire sizes may different from those
of the used wires for the previous servo motors.
When you use a drive unit, "servo amplifier" explained above will be "drive unit".
