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 longer 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,
always confirm from the front of the servo amplifier whether the charge lamp is off or
not.
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, you may get an electric shock.
The cables should not be damaged, stressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may operate
unexpected resulting in injury.
Connect cables to correct terminals to prevent a burst, fault, etc.
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.

Use a noise filter, etc. to minimize the influence of electromagnetic interference,
which may be given to electronic equipment used near the servo amplifier.
Do not install a power capacitor, surge killer or radio noise filter (FR-BIF-(H) option)
with the power line of the servo motor.
When using the regenerative resistor, switch power off with the alarm signal.
Otherwise, a transistor fault or the like may overheat the regenerative resistor,
causing a fire.
Do not modify the equipment.
During power-on, do not open or close the motor power line. Otherwise, a
malfunction or faulty may occur.
