SIGNALS AND WIRING
WARNING
• Any person who is involved in wiring should be fully competent to do the work.
• Before wiring, turn off the power and wait for 20 minutes or more until the charge lamp turns off. Then, confirm that the voltage between L+ and L- is safe with
a voltage tester or others. Otherwise, an electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always confirm it from
the front of the converter unit.
• Ground the converter unit, drive unit, and servo motor securely.
• Do not attempt to wire the converter unit, drive unit, and servo motor until they have been installed. Otherwise, it may cause an electric shock.
• The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause 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 the correct terminals. Otherwise, a burst, damage, etc., may occur.
• 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 converter unit and the drive
unit will malfunction and will not output signals, disabling the emergency stop and other protective circuits.
• Use a noise filter, etc., to minimize the influence of electromagnetic interference. Electromagnetic interference may affect the electronic equipment used near
the converter unit and the drive unit.
• Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF(-H)) with the power line of the servo motor.
• Do not modify the equipment.
• Connect the drive unit power outputs (U/V/W) to the servo motor power inputs (U/V/W) directly. Do not connect a magnetic contactor and others between
them. Otherwise, it may cause a malfunction.
• Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the drive unit may cause a malfunction.
• Before wiring, switch operation, etc., eliminate static electricity. Otherwise, it may cause a malfunction.
