Separate the main circuit and control circuit wiring to prevent erroneous actions.
Use shielded wire for the control wiring and do not expose the peeled-off shield in front of
the terminal.
Use shielded wire or conduit for the power wiring and ground the two ends of the shielded
wire or conduit.
Damaged insulation of wiring may cause personal injury or damage to circuits and
equipment if it comes in contact with high voltage.
The AC motor drive, motor and wiring may cause interference. To prevent equipment
damage, take care of interference between the surrounding sensors and the equipment.
Connect the AC drive output terminals U/T1, V/T2, and W/T3 to the motor terminals U/T1,
V/T2, and W/T3, respectively. To permanently reverse the direction of motor rotation, switch
over any of the two motor leads.
With long motor cables, high capacitive switching current peaks can cause over-current,
high leakage current or lower current readout accuracy. To prevent this, the motor cable
should be less than 20 m for 4.0 kW models and below. The cable should be less than 50 m
for 5.5 kW models and above. For longer motor cables, use an AC output reactor.
The AC motor drives, electric welding machines and the larger horsepower motors should
be grounded separately.
Use ground leads that comply with local regulations and keep them as short as possible.
The VFD-EL-W series does not have a built-in brake unit，and no support for external brake
unit and brake resistor.
When grounding, choose wires that comply with local regulations for your safety.
