Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage cur-
rentwill increase, causingtheInverteroutputcurrent to increase as well.Thismayaffect
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 a ground resistance of 100 Ω or less.
•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.
