Maximum
frequency
selection
Select 120Hz or 400Hz as the upper limit that can be set in the maximum frequency setting (A63)
Adjust the relationship between the external frequency command and the inverter output frequency.
: Voltage command (O-L)
: Current command (OI-L)
This function is factory-set to the appropriate position. If this setting 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relationship between the external frequency command and output frequency is no longer maintained.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 : Put voltage command (10V of 5V) to O-L terminal, and adjust unit output
frequency comes to maximum.
Current command : Put current command (4-20mA) to OI-L terminal, and adjust unit output
frequency comes to maximum.

Set the base frequency and maximum frequency.
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.

frequency : 60Hz (A62) base frequency:60Hz
(A63) maximum frequency :
120Hz
NOTE 1: When a frequency more than the base frequency 60 Hz
is used, the motor is not a general purpose motor but
a sp ecial motor. Therefore, the maximum applicable
motor s et value is different.
When the kW display is the same, the inverter
capacity may be increased.
NOTE 2 : 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.
