(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)
• Ambient temperature:
(2) If the wiring distance is long (approx. 50 meters), reduce the inverter car-
rier frequency as described below.

(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)
