1.5 Power and torque curves
When setting up a drive the torque sequence must be considered in the wanted regulation area.
This can roughly be divided into 3 groups:
• Constantly torque in all regulation area e.g. conveyer
• Rising torque at speed acceleration e.g. Pumps or ventilation.
• Falling torque at speed acceleration e.g. drilling machines or tools machines.
Diagram below might help to choose the right function and power selection.
Power and torque curve
Zone 1: Power rises linear with frequency. Rotation torque M is constant (Mn).
Warning: By continuous run with motor torque below 20 Hz, use a motor size larger or a motor with
ventilation.
Zone 2:
Power is constant (Pn)

2.7 Notes to parameters
The non flashing parameters will normally have the same
functions in the special programs. The flashing parameters
are different from program to program.
Set up the max / min frequency, acceleration and
deceleration first. Then set up the special parameters. The generally parameters are described below.
Par. 1: Max frequency
Set up the maximum output frequency in this parameter.
NOTE (Special function for standard program 0): When the set up min frequency is higher than the
set up max frequency does the output frequency decrease when the reference signal rises. (Inversely
proportional).
Important!
Please note that the motor torque decreases when frequency exceeds the frequency / voltage top point (at
normally 50Hz) If you are using the inverter for ventilation or pumps does the torque rise a lot, at rising
frequency.
Par. 2: Min frequency
In this parameter you set up the minimum output frequency. Set this value to the point were the motor
loses it’s torque or if slow speeds damages the machinery.
Par. 3/4: Acceleration / deceleration
Do not set Acceleration /deceleration higher than necessary. This will spare the mechanical parts and
avoid damages. The setting is in Hz pr. second.
Exampel: Value = 5.0 (default) this corresponds to that it would take 10 sec for the motor to reach 50 Hz
when starting.
Acceleration: Acceleration must not be set too high, this might cause that the current limit of the inverter
is exceeded. At 1,5 times over current does the display flash. At 2 times it TRIPS with the error OC3. In
both cases you need to lower the value of the acceleration. If you need very fast acceleration or need to
move a very big load, use a inverter with a larger power size.
Deceleration: At fast deceleration it might occurs that the motor will function as a generator. The energy
generated will be stored in the DC link capacitors. If the energy get too high the inverter TRIPS at a OU
error. This could be prevented by using longer deceleration ramps or by using a brake chopper inverter
(option)
Par. 5: V/F-Curve (Voltage/Frequency relation)
(Can only be changed when the controller is in OFF mode – Program 0 →Terminal 8 Not activated)
Default 50 Hz (normal mode): Voltage and frequency rises equally until 50 Hz, the voltage is constant at
above 50 Hz. This can be adjusted for special motors.
When using inverters type SC3-…and motors with 230 / 400V – 50Hz is it possible to rise the motor
power with factor 1,73 by setting the V/F curve to 87 Hz and connects the motor in delta ∆3 x 230V. The
inverter power is in this ways 1,73 times bigger. See section 1.5.
Note (Special function for program 0): If the value is set lower than 25 Hz the inverter goes into FAN
mode. This is used for ventilation or pumps with square falling torque at falling rotations. (The display
shows PAR) The motor would work more soundless and use less energy in FAN mode.
Note: Most of the parameters in the
Speed Commander can be set up at run
time. This must be done with care

Standard user guide
V51-00-V19 eng -12- Rights to changes reserved
Par. 6: Boost
When a larger start torque is needed is it possible to adjust
this parameter so there would be up to 25% more voltage
out. Beginning from 0 Hz up to the Frequency/Voltage
cross point. Setting this parameter too high might cause
the inverter to get over heated.
Therefore set the value as low as possible.
(Recommended values see table below).
Par. 7: DC-brake voltage / torque
Deceleration is activated with the STOP / HOLD input
terminal 9.
Note:
The display shows Hb while DC braking.
Par. 8: DC braking time
This is the duration for the time where the DC braking is active. The motor might need ventilation if the
DC braking is used often or have a long brake down time.
Par. 9: Start frequency
This parameter is used for compensating for the motor slip.
The output frequency will start at the value set in this parameter

Par. A: Stop frequency
This parameter works as parameter 9 but this is active when decelerating.
Par. B: Current limit
This can adjust the output current limit from 50% to 150%. If the current limit is exceeded does the
display flash and the output frequency is reduced,
Par. C: TIP - frequency
Frequency when using TIP mode or at reference run.
Par. D: Switch frequency
When the inverter is operating a tone will be heard. This is caused by the inverter switch frequency. In
case of motor resonance, the switch frequency can be changed in range from 2.0KHz to 8.0KHz (Default
2,5KHz). If switch frequency is above 4KHz, is it necessary to reduce the max output current according
to the following table, because of the heat dissipation in the inverter.
Switch Frequency Max output current
2,0 - 4,0 kHz 100%
≤5 kHz 90%
≤6 kHz 80%
≤7 kHz 70%
Note: Low switch frequencies lowers the heat in the
inverter and motor. So don’t change the default values
unless a noiseless performance is needed.

Par. L: Motor revolutions pr min at 50 Hz
PARAMETER L Set up the motors normal rotation pr min at 50 Hz. This is usually seen at the metal
plate on the side of the motor.
Note: This setting is not necessary if used as an ordinary frequency inverter (Par. P also)
Par. P: Encoder pulses pr. rotation
Set up the encoders pulse no pr rotation.
e.g. if a MIG encoders MIG105-14-50 is used (50 pulses pr rotation) Set the value to 50,00.

08 : 0-10volt (terminal 2 and 4 ) controls the frequency.
0-10volt (terminal 3 and 4) controls the voltage / torque between 0 and 100% of normal
torque at the actual frequency.
*At 05 and 06 has 0-10V (potentiometer) the first priority. This function can used as automatic mode at
current signal and manual mode with 0-10V (potentiometer).

2.8 Information about positions tolerance and hysteresis (PAR. U and Y)
(Not available in program no. 0)
The purpose with parameter U is to tell the inverter how accurate the positioning should be. If the ramps
(acceleration /deceleration) were set too high would it result in problems with finding the right position
precisely.
Sample:
PARAMETER U = 3 (Positions tolerance)
PARAMETER Y = 4 (Hysteresis area)
If the present position is 200 and the wanted position is 1000 happens as follows: The motor starts
accelerating with the set up acceleration until et reaches the max frequency. The inverter calculates when
to begin to decelerate to hit the right position. When the wanted position is reached (± 3 positions) is the
DC brake activated. And the output is set to 0 Hz.
When the wanted position is reached is the hysteresis area activated. This means that the motor frequency
is 0 Hz in all the shaded area on fig. 6. Only if the position is forced outside the area is a new positioning
against the wanted position made.

Important:
Following notes must be considered when planning and installing:
• The motor is protected by overheat by a PTC thermo sensor; witch can be connected on terminal 7, or
by a thermo regulator in the motor coils.
• Do not use a frequency dependent motor protection switch, use motor protection relay.
• If the motor wires are switched off at e.g. emergency stop, must the terminal 8 OFF input also be
switched off to avoid overload when restarted.
• Never connect mains supply at the output terminal U V W.
• Never use a “Megger” on the frequency inverter (Isolation test).
• Power up’s - unlimited.
• Install inverter after the EMC rules. See section 2.11
• Control wires must be separated from mains wires and motor wires.
