3. SIGNALS AND WIRING
WARNING
y
Any person who is involved in wiring should be fully competent to do the work.
y
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.
y
Ground the servo amplifier and the servo motor securely.
y
Do not attempt to wire the servo amplifier and servo motor until they have been
installed. Otherwise, you may get an electric shock.
y
The cables should not be damaged, stressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
CAUTION
y
Wire the equipment correctly and securely. Otherwise, the servo motor may
misoperate, resulting in injury.
y
Connect cables to correct terminals to prevent a burst, fault, etc.
y
Ensure that polarity (+,
−
) is correct. Otherwise, a burst, damage, etc. may occur.
y
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 forced stop and other protective circuits.

y
Use a noise filter, etc. to minimize the influence of electromagnetic interference,
which may be given to electronic equipment used near the servo amplifier.
y
Do not install a power capacitor, surge suppressor or radio noise filter with the power
line of the servo motor.
y
Do not modify the equipment.
POINT
CN1A and CN1B have the same shape. Wrong connection of the connectors
will lead to a failure. Connect them correctly.
