8.6 Grounding the driver
Be sure to ground the protective earth terminal (screw size:
M4) of the driver.
Tightening torque: 1.2 N·m (170 oz-in)
You can ground either of the two protective earth terminals.
The terminal not grounded should be connected to the
protective earth lead of the motor cable.
Use a grounding wire (AWG16 to 14: 1.25 to 2.0 mm
2
), and
do not share the protective earth terminal with a welder or
any other power equipment.
When grounding the protective earth terminal, use a round
terminal and affix the grounding point near the driver.

8.7 Connecting the 24 VDC power supply input, regeneration resistor
and electromagnetic brake
Use the CN1 connector (6 pins) to connect the 24 VDC power supply input, regeneration resistor thermal
input and electromagnetic brake. Connect the lead wire (AWG28 to 16: 0.08 to 1.25 mm
2
).

Connecting the 24 VDC power supply input
Connect a power supply of 24±10% VDC, 0.8 A or more.
Once a 24 VDC power supply is connected, you can check the contents of alarms that have generated even
when the main power is cut off. If a motor with electromagnetic brake is used, be sure to connect a 24 VDC
power supply as the electromagnetic brake power.
The 24 VDC power supply will not be used to drive the motor. Connect a 24 VDC power supply as necessary.
