5. CONNECTION OF SERVO AMPLIFIER AND DIRECT DRIVE MOTOR
WARNING
Any person who is involved in wiring should be fully competent to do the work.
Ground the direct drive motor securely.
Do not attempt to wire the direct drive motor until it has been installed. 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 connection areas of the power supply
terminals.
CAUTION
Wire the equipment correctly and securely. Otherwise, the direct drive 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 option)
on the power line of the direct drive motor.
Do not modify the equipment.
Connect the servo amplifier power output (U/V/W) to the direct drive 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 to the direct drive
motor. Therefore, recommended wire sizes may different from those of the used
wires for the previous direct drive motors.
