4.2 Connecting the motor and speed controller
Connect the motor cable connector to the CN2 on the speed controller.
Use a connection cable (supplied or accessory) when extending the wiring distance between the motor and speed controller.
The connection cable can be connected up to 3 pieces. Flexible connection cables are also available as accessories.
Maximum extension distance between the motor and speed controller:
10.5 m (34.4 ft.) [including 0.5 m (1.6 ft.) of the motor cable]
Note
•
Securely plug the motor connector into the speed controller, and fix the cable so as not to give stress to
the connector terminal. Insecure connections may cause malfunction or damage to the motor or speed
controller.
•
Use a motor and speed controller only in the specified combination. Unspecified combination may result in
unusual temperature rise or damage to the product.
4.3 Grounding
Be sure to ground a motor and speed controller using the Protective Earth Terminal
and FG terminal, respectively.
Note
Be sure to ground the motor and speed controller to prevent them from being damaged by static electricity.
Static electricity may cause damage to the product if the Protective Earth Terminals are not grounded.
Motor
Ground close to the motor at a shortest distance using the Protective Earth Terminal
of the motor.

4.4 Connecting the input signals
When the motor is operated and stopped externally,
connect input signals to the TB1.
The operation using the front panel is set at the time of
shipment. Refer to p.22 for how to operate using input
signals (external commands).

Connection example for input signals
All input signals of the speed controller are
photocoupler inputs.
This is a connection example for when the motor
is operated using relays and switches (contact
capacity 15 mA or more).
