Grounding the motor and driver
Grounding the motor
Ground the motor using one of its four mounting holes.
Use a grounding cable of AWG18
(0.75 mm
2
) or more in diameter.
Use a round, insulated crimp terminal in combination with an inner-clip washer and bolt it in
place to secure the grounding connection.
Grounding the driver
Be sure to ground the protective earth terminal (screw size: M4) located on the driver side.
Use a grounding cable of AWG18
(0.75 mm
2
) or more in diameter.
Do not share the grounding cable with a welder or power equipment.
Use a round, insulated crimp terminal to ground the cable near the driver.
Connecting control input/output
Connecting control input/output connector
Connect the control input/output connector (supplied, 36 pins) to the driver.
Solder the control input/output cable (AWG28: 0.08 mm
2
or more) to the connector. Assemble
the connector and connector cover with the supplied screws.
Use a shielded cable, such as the optional shielded cable with connectors (sold separately).
Refer to “Assembling the control input/output connector” on page 34.
Insert the control input/output connector into the control input/output connector CN4 on the
