3. SIGNALS AND WIRING
WARNING
Any person who is involved in wiring should be fully competent to do the work.
Before wiring or inspection, turn off the power and wait for 15 minutes or more until
the charge lamp turns off. 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.
To avoid an electric shock, insulate the connections of the power supply terminals.
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may operate
unexpectedly, 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 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.
Connect the servo amplifier power output (U, V, and W) to the servo motor power
input (U, V, and W) directly. Do not let a magnetic contactor, etc. intervene.
Otherwise, it may cause a malfunction.
