Voltage/frequency
characteristics
200V
series
∙ The base frequency and maximum output frequency are
common, and the voltage can be set between 80 and 240 V.
∙ AVR control can be turned ON or OFF.
∙ Non-linear V/f setting (3 points): The desired voltage (0 to 240
V) and frequency (0 to 599 Hz) can be set.
400V
series
∙ The base frequency and maximum output frequency are
common, and the voltage can be set between 160 and 500 V.
∙ AVR control can be turned ON or OFF.
∙ Non-linear V/f setting (3 points): The desired voltage (0 to 500
V) and frequency (0 to 599 Hz) can be set.
