4 Connection
This chapter explains a connection example of a driver and a motor, connection methods of power supplies, the
grounding method, and others.
The installation and wiring methods in compliance with the EMC as well as protection against noise are also
explained.
For protection against electric shock, do not turn on the main power supply and the
control power supply until the wiring is completed.

Required
*1 Theses cables are provided as our products.
Purchase them separately.
*2 Use the cable for encoder when the length
of the encoder cable of motor is not enough.
• Connect the connectors securely. Insecure connections may cause malfunction or damage to the
motor or driver.
• The lead wires of the cable for electromagnetic brake have polarities, so connect them in the
correct polarities. If the lead wires are connected with their polarities reversed, the electromagnetic
brake will not operate properly.
• Do not wire the power supply cable of the driver in the same cable duct with other power lines or
motor cable. Doing so may cause malfunction due to noise.
• Keep 20 m (65.6 ft.) or less for the wiring distance between the motor and the driver. Extending the
wiring distance to more than 20 m (65.6 ft.) may result in heat generation from the driver or
increase of the electrical noise emitted from the products including the motor and the cable.
•
Before connecting or disconnecting a connector, turn off the main power supply and the control
power supply, and check the PWR/ALM LED and the MAIN POWER LED have been turned off.
•
When disconnecting the motor cable, pull out while pressing the latches on the connector with
fingers.
•
When installing the motor on a moving part, use a flexible cable offering excellent flexibility. Check
the model name on p.85.
