15. MR-J3W-0303BN6 SERVO AMPLIFIER
15.3 Signals and wiring
WARNING
CAUTION
Any person who is involved in wiring should be fully competent to do the work.
Before wiring, turn off the power and check that the charge lamp turns off. Otherwise,
an electric shock may occur. In addition, when confirming whether the charge lamp
is off or not, always confirm it from the front of the servo amplifier.
Ground the servo amplifier and the servo motor securely.
Do not attempt to wire the servo amplifier and servo motor until they have 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 connections of the power supply terminals.
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.
The surge absorbing diode installed to the DC relay for control output should be fitted
in the specified direction. Otherwise, the emergency stop and other protective
circuits may not operate.

Electromagnetic interference may be given to the electronic equipment used near the
servo amplifier. Use a noise filter, etc. to minimize the influence of electromagnetic
interference.
Do not install a power capacitor, surge killer or radio noise filter (FR-BIF option) with
the power line of the servo motor.
Do not modify the equipment.
Connect the servo amplifier power output (U, V, and W) to the servo motor power
input (U, V, and W) directly. Do not let a magnetic contactor, etc. intervene.
Otherwise, it may cause a malfunction.
