3. SIGNALS AND WIRING
WARNING
Any person who is involved in wirin g 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. Otherwis e, 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 ser vo motor securely.
Do not attempt to wire the servo amplifier and ser vo motor until they have been
installed. Otherwise, you may get an electric shock.
The cables should not be damaged, s tressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
CAUTION
Wire the equipment correctly and sec urely. Otherwise, the servo motor may
operate unexpectedly, resulting in inj ury.
Connect cables to correct terminals to pr event a burst, fault, etc.
Ensure that polarity ( , ) is correct. Ot herwise, a burst, damage, etc. may occur.
The surge absorbing diode installed to the DC re lay designed for control output
should be fitted in the specified direct ion. 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 int erference,
which may be given to electronic equipment used near the servo amplifier.
Do not install a power capacitor, surg e 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 a larm signal.
Otherwise, a transistor fault or the like may overheat the regenerative res istor,
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 co nnection of
the connectors will lead to a failure. Connect them correctly.
