3. SIGNALS AND WIRING
WARNING
•
Any person who is involved in wiring should be fully competent to do the work.
•
Before starting wiring, make sure that the charge lamp is off and the voltage is safe
in the tester or the like more than 10 minutes after power-off. Otherwise, you may
get an electric shock.
•
Ground the Converter unit and servo amplifier and the servo motor securely.
•
Do not attempt to wire the Converter unit and 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.
CAUTION
• Wire the equipment correctly and securely. Otherwise, the servo motor may
misoperate 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 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.

• Use a noise filter, etc. to minimize the influence of electromagnetic interference,
which may be given to electronic equipment used near the Converter unit and
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 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.
• Do not modify the equipment.
POINT
• The pin with the same signal name are connected in the servo amplifier.
