4. SIGNALS AND WIRING
WARNING
Any person who is involved in wiring should be fully competent to do the wor k.
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. Otherwise, an e lectric shock may occur. In addition,
always confirm from the front of the servo am plifier whether the charge lamp is off
or not.
Ground the servo amplifier and the servo motor s ecurely.
Do not attempt to wire the servo amplifier and s ervo motor until they have been
installed. Otherwise, you may get an electric s hock.
The cables should not be damaged, stressed excessively, loaded hea vily, or
pinched. Otherwise, you may get an electric sh ock.
CAUTION
Wire the equipment correctly and securely. Other wise, 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 r elay designed for control output
should be fitted in the specified direction. O therwise, the signal is not output due to
a fault, disabling the forced stop (EMG) and other protective circuits.

Use a noise filter, etc. to minimize the influenc e of electromagnetic interference,
which may be given to electronic equipment us ed near the servo amplifier.
Do not install a power capacitor, surge suppress or or radio noise filter (FR-BIF-(H)
option) with the power line of the servo motor.
When using the regenerative resistor, switch p ower off with the alarm signal.
Otherwise, a transistor fault or the like may over heat the regenerative resistor,
causing a fire.
Do not modify the equipment.
During power-on, do not open or close the motor p ower line. Otherwise, a
malfunction or faulty may occur.
