The % value of the above two parameters shall take Parameter 1-00 for reference.
The min as well as max values are mainly set to prevent mishandling of operators, thus protecting motor from
overheating caused by over-low running frequency, or mechanical wearing by an over-high speed.
If max output frequency is set to 80%, and frequency set to (1-00) 60Hz, then max output frequency shall be 48Hz. If
min output frequency is set to 10%, while Min operation frequency (1-05) set to 1.5Hz, it shall run in 6Hz in case of
set frequency is below 6Hz.

The acceleration time during inverter acceleration and deceleration shall be the time used for accelerating from 0Hz
to Max output frequency (1-00); while deceleration time refers to the time for deceleration from Max output frequency
(1-00) to 0Hz.
Applying the 2nd accel/decel time shall be available after the multi-functional terminals are set to switching of 1st and
2nd accel/decel. 2nd accel/ shall be performed when terminals for this function are closed.
As the diagram shows below, the motor adopts area of max output frequency (1-00) from 0Hz for acceleration and
deceleration calculation, If 1-00 is 60.0Hz. Provided that min frequency is 1.0Hz, time for accelerating to 60Hz shall
be 9.83sec, and deceleration to stop shall also be 9.83sec.
