2-8-18 Carrier Frequency
Item name Constant to be set Factory preset
Carrier frequency upper limit No. 40 4
Changing the carrier frequency reduces RFI noise and leakage
current without increasing motor noise.
Carrier frequency (kHz) = 2.5 kHz × constant No. 40 value

Set Value
Maximum Continuous Output Current
1 to 4 Up to 100% of Inverter output current
5 Up to 90% of Inverter output current
6 Up to 80% of Inverter output current
If the wiring distance between the Inverter and motor is long,
reduce the carrier frequency. For details, refer to the wiring precau-
tions described in
1-4 Wiring .

Item name Constant to be set Factory preset
Frequency detection level No. 36 0.0 Hz
Multifunction contact output function No. 34 and No. 35 No. 34 = 0, No. 35 = 1
This function is used when operation at an arbitrary speed must be
indicated. Set the multifunction contact output (No. 34, No. 35) as
follows:
