The output voltage and frequency of the inverter
are proportional up to base frequency, giving a
theoretically constant torque output.
NOTES
1 If base frequency is set higher than maxi-
mum frequency (Function 03), the output
voltage cannot rise to rated voltage.

07 and 43. Accel. time 2 and Decel. time 2 are
selected by activating terminal X4-P24 when
Function 43 = 0 or 2.
Factory-set default values are 10 seconds for
both acceleration and deceleration. Accel. time
2 and Decel. time 2 can be set independently in
the range from 0.1 (F63/64 = 0.00) to 3600s.
When Function 63 or 64 setting = 0.00, the
acceleration or deceleration time is 0.01 sec.

nal X4-P24 selects Accel. time 2 and Decel.

67 automatically.
For Motor 2 only. Refer also to Function 08.
The factory-set default value of Function 65 is
13.
Automatic boost (equivalent to Function 08 = 0)
is not available.
When Function 65 is set to 1, the boost applied
is proportional to the square of the speed (fre-
quency) — a suitable characteristic for fans and
centrifugal pumps.
When Function 65 is set to 2, the boost is pro-
portional to the torque demand.
Linear boost, inversely proportional to speed, is
applied when Function 65 = 3 (low boost)
increasing in unit steps to high boost when
Function 65 = 31.
1 = Squared characteristic (for pumps and fans)
2 = Proportional characteristic
3 = Low linear boost…
…increasing in unit steps to…
31 = High linear boost

nal X4-P24 selects Torque boost 2 and also

cally.
