P008：Max. output frequency
P009：Base frequency
Used to set the maximum output frequency and base frequency.
(Parameter P005 is valid only when "FF" or "3C" is set.)

Note
・
If "P005: V/F pattern" is set to "50" or "60", the max. output frequency and base frequency are
fixed value.
・
A frequency higher than "P100: upper frequency clamp" cannot be output.
・
If a general-purpose motor with a rated frequency of 50 or 60Hz is run at a frequency exceeding
the rated frequency, the motor may be damaged. Always set the frequency to match the motor
characteristics.
・
If the base frequency is required to be changed together with the max. output frequency for a
high-speed exclusive motor, etc., such change is done with this parameter.
・
When running a general-purpose motor with a frequency higher than the universal frequency,
the base frequency will be set to the normal motor's rated output frequency(50 or 60Hz).
・
When using the general-purpose motor at a level higher than the base frequency (normally
50 or 60Hz), the motor will enter the constant output characteristics, and the generated torque
will drop in inverse proportion to the frequency.
