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)

Torque falls with rising frequency

Frequency / Voltage point at 50 Hz Frequency / Voltage point at 87 Hz

If you choose to set the systems max frequency to
75 Hz instead of 50. Is it possible to equalize the
smaller motor torque with a larger gearing in the
gear.
Advantages:

• 1,5 times larger regulations area

• 1,5 times larger torque below 50Hz

• Higher start torque.

• Ventilation of motor might not be needed.

Suitable for 3 phased mains supply( SC3- ) and
motor voltages at 230 / 400V by setting the motor in
delta ∆. This way you take advantage of the linear
V/F curve until 87Hz. The motor is supplied with
230V at 50 Hz and 400V at 87Hz
Advantages:

• 1,73 times larger regulations area

• 1,73 times larger motor power at 1,73 times

larger frequency inverter power.

• 100% torque from above 87 Hz.

2 Installation

2.1 Generally

The SPEED-COMMANDER frequency inverter makes it possible to regulate the speed of a 3-phased AC
motor in power ranges until 22Kw

This manual must follow the inverter to secure correct installation. Please check the following points:

• Is the supplied device in the ordered power range?

• Is the inverter damaged under transportation?

• Is internal parts or connections plugs damaged or loose?

2.2 Mounting and installation
Safety precautions:

• Connection and setup must be carried out by trained personal.

• Trained personal must be familiar with all the safety precautions in this manual.

• Avoid touching the high voltage parts while powered up and until 5 min after mains power is

removed.

• When working with electrical systems always have a second trained person present in case of

emergency. This person could stop the system and give first aid.

• The motor terminal might contain high voltage even when motor not running.

• The inverter might start unwanted after power up (depends on the parameter setting).

• Connection and setup must be carried out in order of the electricity regulations.

Mounting description:

• The inverter must be mounted vertically to ensure that the heat sink functions correct and air can flow

freely through.

• When mounting inside a box ensure that there are at least 80mm for SC-750/5 to SC3-2200/5 and

100mm for SC3-4000/5 to SC3-22000/5 of free space over and under the inverter.

• In some cases it might be necessary to make calculations on the heat caused by the heat loss in the

inverter to ensure long lifetime.

• Avoid strong vibrations.

• The surrounding conditions of the inverter have influence on the lifetime and functionality of the

device.

Following demands must be kept:

• Ambient temperature 0º C to +40º C

• Humidity less than 90% (non condensation)

• Protection against noise, metal particles, humidity, corrosion and explosive gasses.

• Max. Altitude 1000m above sea

Standard user guide

V51-00-V19 eng

Note!

• High ambient temperature reduces the electronically lifetime considerably.

• If fan is mounted please check it frequently.

• The Speed Commanderen must not be exposed to vibrations, humidity, water, dust and aggressive

gasses.

• Max altitude: 1000 meter above sea.

Reductions factor: Ambient temp.: Output current:
At ambient temperature above
40°C is it necessary to reduce the
max output current after
following table:

≤40°C
≤45°C
≤50°C
≤55°C

The suppluer / manufacture cannot be held responsible for any damage cursed by wrong treatment,
unauthorized operation or badly maintenance of the device.

Important! In case of problems that cannot be identified, please contact supplier

2.3 Decision of motor direction

First try the direction of the motor with TIP in small movements. The inverters control inputs are
disconnected so it enters the OFF mode. Now activate the

STEP/STORE button in 2 sec and while

pressing the button press the ▲ button for forward or the ▼ for reverse.

Note that STEP/STORE must

be activated else dose the motor stop. If the motor goes in the wrong direction, change 2 of the motor
wires. (Remove mains power and wait for 5 min)

NOTE The drive direction against the reference switch

is

reverse

2.4 Decision of the counter direction (When using encoder)

Check the counter direction in small steps with TIP function a described above. The counter must count
up when TIP’ing forward and down when reversing. If it is opposite change the encoders A/B wires
terminal 11 and 12.

Warning! Avoid touching the electronically parts while powered up and until 5 min after mains
supply has been removed. The frequency inverter restarts automatically when powered on if
automatic restart is selected.
