3.SIGNALS AND WIRING
Any person who is involved in wiring should be fully competent to do the work. Before starting wiring, make sure that the voltage is safe in the tester more than 10 minutes after
WARNING 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.
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 forced 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 servo amplifier.
Do not install a power capacitor, surge suppressor or radio noise filter
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
CN1A, CN1B, CN2 and CN3 have the same shape. Wrong connection of the connectors will lead to a failure. Connect them correctly.
