8.5 Connecting the power supply
Use the CN3 connector (7 pins) to connect the power supply cable (AWG16 to 14: 1.25 to 2.0 mm
2
) to the
main power supply connector (CN3) on the driver. Refer to p.30 for details on the connector wiring method.
Use a power supply capable of supplying the current capacity as below table.
Note
• Do not wire the power supply cable of the driver in the same cable duct with other
power line or motor cable. Doing so may cause malfunction due to noise.
• Before plugging/unplugging the CN3 connector, turn off the power and wait for the
CHARGE LED to turn off. Failure to do so may cause electric shock due to residual
voltage.
• The current capacity for the power supply as shown below is the value when operating
the motor in the continuous duty region. When operating in the limited duty region, the
current will flow maximum three times as much as the continuous region. Refer to p.159
for the continuous duty region and limited duty region.
