When the frequency is set so that the base
frequency is larger than the maximum
frequency, the base frequency is forced
to be made equal to the maximum
frequency at the start of running.

NOTE 1:
NOTE 2:
When a frequency more than the base frequency 60 Hz
is used, the motor is not a general purpose motor but
a special motor. Therefore, the maximum applicable
motor set value is different.
When the kW display is the same, the inverter
capacity may be increased.
Set the base frequency according to the specifications
of the motor. When the base frequency is set to less
than 50 Hz, the motor may be burned.

This function is factory-set to the appropriate position. If this setting is changed unnecessarily, the
correct relationship between the external frequency command and output frequency is no longer
maintained. This will result in poor control performance. Adjust the setting of this function only
when the output frequency does not conform to the external command.
Adjustment method
Voltage command:
Current command:
Put voltage command (10V of 5V) to O-L terminal, and adjust unit
output frequency comes to maximum.
Put current command (4-20mH) to OI-L terminal, and adjust unit
output frequency comes to maximum.
