‘shelved’, ie limited to the value set in Function
05 regardless of increasing output frequency.
The factory-set default value of Function 05 is
230 [400].
For Motor 1 only. Refer also to Functions 63
and 64.
Factory-set default values are 6 seconds for both
acceleration and deceleration. Accel. time 1
and Decel. time 1 can be set independently in
the range from 0.1 (F06/07 = 0.00) to 3600s.
When Function 06 or 07 setting = 0.00, the
acceleration or deceleration time is 0.01 sec.
For Motor 1 only. Refer also to Function 65.
The factory-set default value of Function 08 is
0, giving an automatic increase of voltage out-
put
∝
I
load
at starting speed to overcome the
mechanical ‘stiction’ of a typical installation.
(The diagram is not to scale.)
When Function 08 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 08 is set to 2, the boost is pro-
portional to the torque demand.
Linear boost, inversely proportional to speed, is
applied when Function 08 = 3 (low boost)
increasing in unit steps to high boost when
Function 08 = 31.
0 = Automatic torque boost
1 = Squared characteristic (for pumps and fans)
2 = Proportional characteristic
3 = Low linear boost…
…increasing in unit steps to…
31 = High linear boost
Adjusts the DC analog maximum voltage out-
put at terminal FMA in the range from approx.
6.5V to approx. 10.5V so that the full scale of
the analog instrument can be used.
The setting range is 0 (= 6.5V approx.) to 99 (=
10.5V approx.), giving very fine adjustment.
NOTE Function 09 is active only when
Function 40 = 0. Refer also to Function 41.
Adjusts the inverter for the pole-number of the
applied motor so that the LED display shows
the correct motor field speed in rpm.
The adjustment range is from 2 to 12 poles in
steps of 2 poles. Factory-set default is for 4-
pole motors.
Example: If a 4-pole motor is running at 50Hz
the LED display will show
120 x 50Hz ÷ 4poles = 1500rpm
The 7-segment LEDs display can be set to dis-
play ‘line speed’ ie the related speed of the
driven machine, if required (refer to page 16).
Function 11 permits a coefficient or factor to
be applied to the inverter output frequency to
convert the display value to an equivalent in
metres per minute.
Setting ranges
from 0.01 to 9.99 in steps of 0.01
from 10.0 to 200.0 in steps of 0.1
