Others
• To ensure that potential difference will not occur between the motor/driver and
peripheral control system equipment, earth the cable directly to the grounding point.
• When the relay and magnetic switch are used together, make sure that the surge is
absorbed by the mains filter and CR circuit.
• The length of the cables should be as short as possible; do not use long cables with the
excess portion wound in a bundle.
• Keep the power cables such as the motor cable and power cable away from the signal
cables and connect them separately from each other as far as possible [For example,
keep them 100 to 200mm (3.94 to 7.87in.) apart from each other]. Signal cables should
only cross the path of motor or power cables at right angle. The AC input cable and
output cable of the mains filter should be kept away from each other.
Precautions concerning static electricity
Static electricity can make the driver malfunction or destroy it. Handle the driver carefully
when its power is on.
Always use an insulated screwdriver when adjusting the motor current with the driver’s
internal control (VR) or switch.
When using a driver mounted on the current check terminals, adjust the current in the
following manner.
1.Switch off the driver power supply.
2.Insert the tester into the current check terminals.
3.Switch on the driver power supply.
4.Adjust the current by adjusting the internal control (VR) with an insulated screwdriver.
5.Switch off the driver power supply, then remove the tester.
Note: Do not approach or touch the driver with the power on.

The standard length of the motor cable is 23.6in. (600mm).
The length of the cable between the driver and controller is 78in. (2,000mm).
