14.3 Signals and wiring
WARNING
Any person who is involved in wiring should be fully competent to do the work.
Before wiring, turn off the power and wait for 15 minutes or more until the charge
lamp turns off. Then, confirm that the voltage between P and N is safe with a
voltage tester and others. 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 direct drive motor securely.
Do not attempt to wire the servo amplifier and direct drive 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.
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.
The surge absorbing diode installed to the DC relay for control output should be fitted
in the specified direction. Otherwise, the emergency stop (EM1) 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) on
the power wire of the direct drive motor.
