•For special applications, please contact us for further information.
Considerations for Compressor use
For each compressor, the compressor data from the manufacturer datasheet must be hard wired into the
frequency converter software by LS Control. Afterwards the specific compressor is selected by means of dip
switches. Since the compressor parameters change with changing loads, LS Control must carry out a
performance test on each individual compressor to select the best parameters covering the widest range of
operating patterns ensuring that the compressor will be able to operate at high loads as well as low loads.
The result of the performance test will give a new max. current and new max. RPM for correct operation of
the compressor in question.
Rule of thumb! When using a compressor with a frequency converter, make sure that the input power to
the compressor is below the maximum power of the frequency converter and that the frequency converter
can deliver the required current for the compressor.
Application considerations with compressors
To choose the right compressor for your specific application, it is important to compare the compressor
data with the frequency converter data. Make sure that both the frequency converter and the compressor
can supply the required power and current for your application.
At high loads the frequency converter may become extremely warm. Therefore, if the compressor is
operated at high loads and high ambient temperatures, active cooling might be necessary. Please refer to
chapter Electrical / Mechanical installation.
NB! It is your responsibility to ensure that the installation in all meets the EMC standards applying for your
specific installation and the environment in which it is installed.

EMC
The frequency converter (IP54) complies with the standard of electrical Power Drive Systems. The
frequency converter is classified as a Power Drive System (PDS) of ”category C2” (EN 61800 – 3).
•EN 61800 –3:2005 –Adjustable speed electrical power drive systems - Part 3: EMC requirements
and specific test methods.
•EN 61800 –3/A1:2012 –Adjustable speed electrical power drive systems - Part 3: EMC
requirements and specific test methods.
•EN 61800 –5 –1:2007 –Adjustable speed electrical power drive systems - Part 5-1: Safety
requirements - Electrical, thermal and energy.
If a frequency converter is purchased without enclosure (IP00), LS Control cannot ensure that the frequency
converter complies with the above standards.
Warnings
Before the frequency converter is taken into use, verify that the frequency converter specifications are
compatible with the mains to which it is going to be connected. Furthermore, verify that the motor is suitable
for frequency converter connection and that it is in compliance with the frequency converter specifications.
Check the place of installation for any special requirements and precautions which must be observed during
installation, commissioning or operation. The frequency converter must be supplied through a mains switch
with at least 3mm breaker space between all conductors according to IEC364. The fuse installed in the
electrical switchboard must be 13A or less for SpeedControl 1047 1.5KW. The frequency converter must
always be connected to yellow/green grounding conductor (PE) in supply.

If the frequency converter is connected to an installation with a residual current device as an extra protection,
the device must be marked with the following symbol: HPFI/PFI
The components of the power unit of the frequency converter are live when it is connected
to mains. Getting in contact with this voltage is extremely dangerous and may cause death or
severe injury. The control unit (connection 1-10) is isolated from the mains potential.
The motor terminals U, V and W are live when the frequency converter is connected to mains,
even when the motor is not running.
The control I / O terminals are isolated from the mains potential (clamps 1 –10). However,
dangerous control voltage may be present at the relay output terminals (9 and 10) even when
the frequency converter is disconnected from mains.
The earth leakage current may exceed 3.5 mA AC when the frequency converter is connected
to a motor. According to standard EN61800-5-1 a reinforced protective ground connection
must be mounted.
If the frequency converter is part of a machine solution, the machine manufacturer is
responsible for providing the machine with a main switch. (EN60204-1).
If the frequency converter is disconnected from mains while the motor is running, high and
dangerous voltage may still be present on the frequency converter power unit. In this case
the motor is operating as a generator supplying the frequency converter with power.
After disconnecting the frequency converter from mains, wait a minimum of 5 minutes before
handling the frequency converter.
The frequency converter may automatically start the motor after a fault situation or after
reconnection of mains. Note that there might be a minimum downtime during which the
motor cannot be stopped.
In a domestic environment this product may cause radio interference in which case
supplementary mitigation measures may be required.
Intended for use in first environment, that includes domestic premises, it also includes
establishments directly connected without intermediate transformers to a low-voltage power
supply network which supplies buildings used for domestic purpose.
Note! The frequency converter is only EMC compliant when supplied in IP54 model. If the
frequency converter is supplied without enclosure (IP00), the customer will be responsible for
EMC compliance.
The frequency converter is sensitive to ESD (ElectroStatic Discharge). Handle with care. ESD
may cause damage to the frequency converter.

Description of Functions
Supply
The frequency converter is supplied by 230VAC ±10%. However, it is possible to lower the voltage, but it is
not recommended to use a supply less than 200VAC.
Control Voltage
1 –10 Vdc = min. rpm –max. rpm (6 phase motor => 200rpm –1000rpm => 10 –50 Hz). If control voltage
gets lower than 1 Vdc the frequency converter will run min. rpm. The control voltage levels can be adjusted
via the Modbus-interface. (See separate ModBus document).
RUN input
If the RUN input is activated (added to GND from internal supply) the frequency converter will start the
motor. The RUN input can be disabled through the Modbus-interface. (See separate ModBus document).
Alarm Relay
The frequency converter is supplied with an alarm relay which is activated when there are no faults. If the
frequency converter must stop due to severe error, the relay will be deactivated (it changes position). The
alarm relay is deactivated when supply is disconnected. The function of the alarm relay can be changed via
the Modbus-interface. (See separate ModBus document).
HW Stop switch
The frequency converter is supplied with a Hardware (HW) Stop switch function. This HW Stop Function can
be used with a switch (e.g. a pressure switch or a thermal switch). The Switch must be connected between
connector 16 and 17, and it must be closed for the frequency converter to run the motor. If the switch is
open, the frequency converter is stopped, and it will not be able to restart, until the supply voltage has
been disconnected long enough for the frequency converter to come to a complete stand still.
If not used, connector 16 and 17 must be shortend.
Current Limits
Current limits can only be adjusted via the Modbus-interface. (See separate ModBus document). The
current limits are as standard set to the current printed on the motor plate. When the frequency converter
registers that the current limit is exceeded, it will automatically reduce the speed of the motor. However,
the speed will never be reduced further than minimum speed. The time delay before the motor stops
depends on the current and the overrun time which are integrated into the intelligent protection algorithm
in the control.
Temperature
The temperature function is set to ensure that if the frequency converter power unit registers an excess temperature
it will reduce the motor speed. However, the speed will never be reduced further than the minimum speed. The
motor speed reduction will be slow. Should the temperature continue to increase, despite the speed reduction, the
frequency converter will stop and indicate error. The temperature reduction function is part of the intelligent
User Guide for SpeedControl 1047
• LS Control A/S • Industrivej 12 • DK –4160 Herlufmagle Page 7
protection algorithm. The temperature setting for where the frequency converter should start to reduce the speed
can be lowered by means of the ModBus-interface. (See separate ModBus document).
Skip areas
It is possible to enter up to 5 skip areas via the ModBus-interface. These skip areas may be used to avoid RPMs
where the application generates excessive noise or vibration. These areas are avoided in that the skip frequencies
in a given area automatically will be passed by the frequency converter, and in that way avoiding noisy and
vibrating operating frequencies. All skip areas are equipped with the same hysteresis value defined by a preset
distance from the RPM center. This distance determines how far away the frequency converter needs to adjust the
speed from the entered center RPM. See separate ModBus document for detailed description on how to adjust
these skip areas. By default, they are all disabled.
Electrical / Mechanical Installation
Important
A time delay of approx. 3 - 30 sec will occur at start up. If the PCB is dismounted from the metal housing, the
warranty will be void. Before handling the frequency converter, it must have been disconnected from supply
power for at least 5 min.
Location
The frequency converter is cooled by passive air circulation. To avoid reduced operation or operating stops
due to overheating of the frequency converter, the frequency converter must be mounted vertically on a
metal plated wall with the glands facing downwards. The frequency converter must be mounted with space
around it to ensure sufficient cooling by allowing free circulation of air. Make sure that the mounting surface
can withstand the temperature of the surface of the frequency converter.
User Guide for SpeedControl 1047
• LS Control A/S • Industrivej 12 • DK –4160 Herlufmagle Page 8
Operating temperature
The frequency converter must be installed in a well-ventilated environment. The surrounding temperature
must not exceed 40°C and the frequency converter must never be mounted in a location where it is
exposed to direct sun light.
The 1047-1500 will be able to run at maximum supply power without additional cooling at 40°C ambient
temperature. As long as sufficient airflow through the cooling fins of the heat sink is ensured.
The frequency converter will reduce performance of the motor, if a too high temperature is measured. By
default, this temperature is set at maximum, but it can be adjusted down through the ModBus interface.
Supply
The frequency converter is supplied by mains (230VAC ±10%) with minimum 3 x 1.5 mm2 cable. The distance
between supply cable and motor cable must be as long as possible (> 30 cm). If it is neccessary to cross the
power cable and the motor cable, this must be done at an angle of 90°. The PE-conducter from the motor,
which is screwed into the terminal block, must be longer than L and N. The fuse installed in the electrical
switchboard must be 13A or less for E1045-1500 and 16A or less for E1045-2000.
Due to relatively high leakage currents in the frequency converter and the motor, the frequency converter
and the motor must always be properly grounded in accordance with national and local regulations. The
ground conducter should be as short as possible to avoid high frequency radiation.
Supply Connection
PE Protective grounding (supply)
N Neutral (supply)
L Live (230VAC) (supply)
Motor
The motor is connected to the frequency converter by minimum 4 x 1.5 mm2 shielded cable. The total cable
length must not exceed 20 m, keep it as short as possible. Long cables may cause function failure. The motor
cable must be shielded and be mounted correctly in the metal gland or to the PCB with a cabel clamp to
minimize electrical noise from the motor. PE conductors must be longer than U, V and W.

The PCB is equipped with LED lights. LED1 to LED7.
Modbus LED lights
LED5 (red) and LED6 (green) are modbus LED lights. See page ”9”for LED locations.
LED6 flashes fast when communicating.
LED5 has no function.
Motor LED lights
LED1 (red) and LED2 (green) are controlled by the circuit regulating the motor.
See page ”9”for LED locations.
Start
When the frequency converter is connected to mains, the following pattern is shown:
1. LED1 is turned off and LED2 is lit constantly => processor initialization
2. After 5 –10 seconds LED1 flashes a number of times to indicate the motor selected by the DIP
switches. This also indicates that the motor in questions has been initialized in the processor.
3. At last LED1 turns off and LED2 starts flashing.
Operation
When there are no errors LED2 will be flashing. LED2 flashes when the motor is running and when it is
stopped. This indicates that everything is running normally.
Errors
If an error is detected, the frequency converter will stop the motor, turn on LED1 and turn off LED2.
HW Stop Function LED lights
LED7 (red) is controlled by the HW Stop function. When it flashes it is indicating that the switch is closed
and the HW Stop Function is not blocking the Frequency Converter.
If LED7 (red) is on constantly, it is indicating that the Frequency Converter has been blocked by the HW Stop
Function, and that it will not be able to continue until the Supply Voltage has been removed long enough
for the Frequency Converter to completely turn off and on again.

See page ”9”for LED locations.
Start
When the frequency converter is connected to mains, the following pattern is shown:
1. LED3 turns on and LED4 flashes fast.
2. After 5 –30 seconds (when the power electronics has been initialized and indicated the motor
choice), LED3 will turn off and LED4 will flash slowly.
Operation
When there are no errors LED4 flashes slowly and LED3 is turned off. This pattern is shown both when the
motor is stopped or running. It indicates that everything is running normally.
Restart
When an error is detected, and the frequency converter is waiting to restart, LED3 and LED4 will be flashing
at the same frequency. When restart is activated, a new start is initialized.
Errors
If an error is detected, the circuit will indicate the error by flashing LED3 and turn off LED4. At the same
time the modbus registers 03x0009 and 03x0010 will be set to a value corresponding to the error. Modbus-
register 03x0011 will be set, if the frequency converter is unable to restart and resume operation.
