Induction Noise: Electromagnetic induction generates noise on the signal line, causing the controller
to malfunction.
Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting radio
receiver to make noise.
D Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage current 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 C06-01 to C06-03 or n050) as shown in the table below. (For
details, refer to the parameter settings.)
Model
Cable length 20 m max. 40 m max. More than 40 m
Carrier frequency 15 kHz max. 10 kHz max. 5 kHz max.
