3. SIGNALS AND WIRING
WARNING
Any person who is involved in wiring should be fully competent to do the work.
Before starting wiring, switch power off, then wait for more than 15 minutes, and
after the charge lamp has gone off, make sure that the voltage is safe in the tester
or like. Otherwise, you may get an electric shock.
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
misoperate, 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 designed for control output
should be fitted in the specified direction. Otherwise, the signal is not output due to
a fault, disabling the emergency stop (EMG) and other protective circuits.

Servo amplifier
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 suppressor or radio noise filter (FR-BIF
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.
