Carrier Frequency Varies According to Inverter Capacity (kVA).
(3) Carrier frequency can be automatically reduced to 2.5 kHz when (n75) is set
to 1 and the following conditions are satisfied.
Output frequency < 5Hz
Output frequency > 100%
Factory Setting (n75) is 0 (disabled)

(1) Reduce continuous output current by changing carrier frequency to a
setting of 4 (10 kHz) for 200V class inverters (size > 1.5kW) and all 400V
class inverters. Refer to the table above for the reduced current.
[Operation Condition]
• Input power supply voltage: 3-phase 200 to 230V (200V class)
Single-phase 200 to 240V (200V class)
3-phase 380 to 460V (400V class)
• Ambient temperature: 14 to 122

rier frequency as described below.
