3.WIRING
WARNING
CAUTION
CN1A, CN1B, CN2 and CN3 have the same shape. Wrong connection of the
NOTICE
connectors will lead to a failure. Connect them correctly.
1. Any person who is involved in wiring should be fully competent to do
the work.
2. Before starting wiring, make sure that the voltage is safe in the tester
more than 10 minutes after power-off. Otherwise, you may get an
electric shock.
3. Ground the servo amplifier and the servo motor securely.
4. Do not attempt to wire the servo amplifier and servo motor until they
have been installed. Otherwise, you may get an electric shock.
5. The cables should not be damaged, stressed excessively, loaded
heavily, or pinched. Otherwise, you may get an electric shock.
1. Wire the equipment correctly and securely. Otherwise, the servo mo-
tor may misoperate, resulting in injury.
2. Connect cables to correct terminals to prevent a burst, fault, etc.
3. Ensure that polarity (+, -) is correct. Otherwise, a burst, damage, etc.
may occur.
4. 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
and other protective circuits.

5. Use a noise filter, etc. to minimize the influence of electromagnetic
interference, which may be given to electronic equipment used near
the servo amplifier.
6. Do not install a power capacitor, surge suppressor or radio noise
filter (FR-BIF option) with the power line of the servo motor.
7. When using the regenerative brake resistor, switch power off with the
alarm signal. Otherwise, a transistor fault or the like may overheat
the regenerative brake resistor, causing a fire.
8. Do not modify the equipment.
