Maker maintenance
For maker maintenance. Do not connect anything.
✔
For connection to CNB and EN1, be sure to use the dedicated cables. The cables cannot be cut off nor
spliced due to the specifically designed lines.
✔
If main circuit power supply is used as single phase power source, specification of supply voltage is
different depending upon motor and driver used.
2) Wire
Electric wires for use in driver main circuit power are shown below.

✔
The information in this table is based on rated armature current running through three bundled lead
wires at ambient temperature of 40[°C]. Use the electric wire beyond proof-pressure 600[V].
✔
When wires are bundled or put into a wire-duct, such as a hardening vinyl pipe or a metallic conduit,
take the allowable current reduction ratio into account.
✔
At high ambient temperature,, service life of the wires becomes shorter due to heat-related
deterioration. In this case, we recommend using heat-resistant vinyl wires.
