3. SIGNALS AND WIRING
WARNING
Any person who is involved in wiring should be full y competent to do the work.
Before wiring, turn off the power and wait for 15 minut es or more until the charge
lamp turns off. Then, confirm that the volt age between P and N is safe with a
voltage tester and others. Otherwise, an electr ic shock may occur. In addition,
always confirm from the front of the ser vo amplifier whether the charge lamp is off
or not.
Ground the servo amplifier and the ser vo motor securely.
Do not attempt to wire the servo amplifier and s ervo motor until they have been
installed. Otherwise, you may get an electric shock.
The cables should not be damaged, stressed exc essively, loaded heavily, or
pinched. Otherwise, you may get an elec tric shock.
CAUTION
Wire the equipment correctly and sec urely. 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, dam age, etc. may occur.
The surge absorbing diode installed to the D C relay designed for control output
should be fitted in the specified direc tion. Otherwise, the signal is not output due to
a fault, disabling the forced stop (EMG) and other protective circuits.

Servo amplifier
Use a noise filter, etc. to minimize the influence of electrom agnetic interference,
which may be given to electronic equipment used near t he 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, switc h 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 m otor power line. Otherwise, a
malfunction or faulty may occur.
POINT
CN1A, CN1B, CN2 and CN3 have the same shape. Wrong connection of
the connectors will lead to a failure. Connect them correctly.
