Connection
This chapter explains a connection example of a driver and a motor, connection methods of a main power supply and
a control power supply, and others.
It also explains installation and wiring methods to conform to the EMC as well as measures against electrical noise.
For protection against electric shock, do not turn on the main power supply and the
control power supply until the wiring is completed.

Connect to CN1
RS-485 communication cable
*1 It is an Oriental motor cable. Purchase is required separately.
*2 Connecting the control power supply allows you to continue monitoring even if the main power supply is shut off.
Connect it as necessary.
*3 It is recommended that a circuit breaker or a circuit protector is connected because incorrect wiring may cause the
internal input circuit to short-circuit.
•
Connect the connectors securely. Insecure connections may cause malfunction or damage to the
motor or driver.
•
When connecting the cables, secure them so that no load is applied to the CN1 to CN3 connectors.
Applying a load to the connector may result in a connection failure, causing the driver to
malfunction.
•
Keep 10 m (32.8 ft.) or less for the wiring distance between a motor and a driver. Exceeding 10 m
(32.8 ft.) in the wiring distance may result in increase of the electrical noise emitted from the driver.
•
Keep 2 m (6.6 ft.) or less for the cable length of the main power supply and control power supply.
•
Before connecting or disconnecting a connector, turn off the main power supply and the control
power supply, and check the POWER/ALARM LED has been turned off.
•
When disconnecting the connector, pull out while pressing the latches on the connector with
fingers.
•
GND of the power supply connector and SG of the RS-485 communication connector are
electrically insulated.
