In case the reference frequency is lower than the maximum frequency (F03)
The actual acceleration and deceleration times are shorter than the specified ac-
celeration time and deceleration time.
• If you choose S-curved acceleration/deceleration or curvilinear accel-
eration/deceleration in "curvilinear acceleration/deceleration" (H07),
the actual acceleration/deceleration times are longer than the specified
times.
• If you specify an improperly short acceleration/deceleration time, then
the current limiting function or the automatic deceleration function ma
activated, resulting in an actual acceleration/deceleration time longe
than the specified one.

In general, there are two different properties of loads--the variable torque loud (fans
and pumps) and the constant torque load (industrial machinery). You can select a
V/f pattern optimized to the load property.
