Grounding
When installing the motor and driver, connect their Protective Earth
Terminals .
Two Protective Earth Terminals are provided on the driver.
Either of the two Protective Earth Terminals can be used for grounding the
driver. The terminal that is not grounded can be used as a spare terminal.
Use the spare terminal according to your specific need, such as connecting it
to the motor in order to ground the motor.
Do not share the Protective Earth Terminal with a welder or any other power
equipment.

Precautions about static electricity
Static electricity may cause the driver to malfunction or suffer damaged.
Be sure to ground the motor and driver to prevent them from being damaged
by static electricity.
Connecting the motor (CN1/CN2/N4)
Connect the motor power connector to the CN2, and the motor signal
connector to the CN4 on the driver. When using an electromagnetic brake
type motor, also connect the electromagnetic brake connector to the CN1.
When extending the wiring distance between the motor and driver, use the
connection cable (supplied or accessory). Connection can be extended to a
maximum of 20.4 m (66.9 ft.).
Connecting the 24 VDC power supply
The 24 VDC power supply is for the control circuit of the driver.
Be sure to connect a power supply which voltage is 24 VDC −15% to +20%
and current is 1 A or more, to the CN5.

power supply
Note
•
When connecting the 24 VDC power supply, check the
indication of the driver case and pay attention to the polarity
of the power supply. Reverse-polarity connection may cause
damage to the driver.
•
When cycling the 24 VDC power, turn off the power and wait
for the PWR/ALM LED to turn off.
Selecting a power supply for I/O signals
The driver comes with a built-in power supply.
To control the operation using relays and
switches, set the SW3-No.3 of the function
setting switch1 to the ON side to select the
built-in power supply.
SW3
Factory setting:
OFF (an external power supply is used)
Note
The built-in power supply cannot be used with the source
logic. If the source logic is used, do not turn the SW3-No.3 of
the function setting switch1 to the ON side.
Connecting the I/O signals (CN5/CN6)
Connect the input signals to the CN5, and connect the speed setting input
signals and output signals to the CN6.
Applicable lead wire: AWG26 to 20 (0.14 to 0.5 mm
2
)
Length of the insulation cover which can be peeled: 8 mm (0.31 in.)
8 mm (0.31 in.)
Insert the lead wire while pushing
the button of the orange color with
a screwdriver.
