Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage cur-
rent will increase, causing the Inverter output current to increase as well. This may affect
peripheral devices. To prevent this, adjust the carrier frequency (set in n37) as shown in
the table below.
Cable length between Inverter and motor 50 m max.
100 m max.
Carrier frequency (n37)
10 kHz max. (1, 2, 3, 4)
5 kHz max. (1, 2)

Ground Wiring
•
Always use a ground terminal with the following ground resistance.
200-VAC Class:
100
Ω
or less
400-VAC Class:
10
Ω
or less
•
For 400-VAC-class models that conform to EC Directives, also connect to the neutral
of the power supply.
•
Do not share the ground wire with other devices such as a welder or power tool.
•
Always use a ground wire that complies with technical standards on electrical equip-
ment. Route the ground wire so that the total length is as short as possible.
•
When using more than one Inverter, be careful not to loop the ground wire.
