Important User Information
(2) Wiring
Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the output of the inverter.
The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the
motor.
Incorrect terminal wiring could result in the equipment damage.
Reversing the polarity (+/-) of the terminals could damage the inverter.
Only authorized personnel familiar with LG inverter should perform wiring and inspections.
Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily injury.
(3) Trial run
Check all parameters prior to operation. Changing parameter values might be required depending on the load.
Always apply permissible range of voltage to the each terminal as indicated in this manual. Otherwise, it could
lead to inverter damage.
(4) Operation precautions
When the Auto restart function is selected, stay away from the equipment as a motor will restart suddenly after
a fault stop.
The Stop key on the keypad is valid only when the appropriate function setting has been made. Prepare an
emergency stop switch separately.
If a fault reset is made with the reference signal present, a sudden start will occur. Check that the reference
signal is turned off in advance. Otherwise an accident could occur.
Do not modify or alter anything inside the inverter.
Motor might not be protected by electronic thermal function of inverter.
Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment
may be affected.
In case of input voltage unbalance, install AC reactor. Power Factor capacitors and generators may become
overheated and damaged due to potential high frequency noise transmitted from inverter.
Before operating unit and prior to user programming, reset user parameters to default settings.
Inverter can easily be set to high-speed operations. Verify capability of motor or machinery prior to operating
unit.
Stopping torque is not produced when using the DC-Break function. Install separate equipment when stopping
torque is needed.
(5) Fault prevention precautions
Provide a safety backup such as an emergency brake which will prevent the machine and equipment from
hazardous conditions if the inverter fails.
(6) Maintenance, inspection and parts replacement
Do not conduct a megger (insulation resistance) test on the control circuit of the inverter.
Refer to Chapter 13 for periodic inspection (parts replacement).
(7) Disposal
Handle the inverter as an industrial waste when disposing of it.
(8) General instructions

2. Installation
When two or more inverters are installed or a ventilation fan is mounted in inverter panel, the inverters and ventilation
fan must be installed in proper positions with extreme care taken to keep the ambient temperature of the inverters
below the permissible value. If they are installed in improper positions, the ambient temperature of the inverters will rise
and ventilation effect will be reduced.
Install the inverter using screws or bolts to insure the inverter is firmly fastened.

When it is desired to avoid resonance attributable to the natural frequency of a mechanical system,
these parameters allow resonant frequencies to be skipped. Three different areas of [Skip frequency
High/Low limit] can be set with the skip frequencies set to either the top or bottom point of each area.
However, during acceleration or deceleration, the run frequency within the set area is valid.
In the case of increasing frequency setting as shown above, if frequency set value (Analog setting
via voltage, current or digital setting via keypad) is within the range of Skip frequency, it maintains Skip
frequency low limit value. If the set value is outside the range, it increases the frequency.
In the case of decreasing frequency setting, if frequency set value (Analog setting via voltage,
current or Digital setting via keypad) is within the range of Skip frequency, it maintains Skip frequency
high limit value. If the set value is outside the range, it decreases the frequency.

It is mainly used to release mechanical brake in elevators after operating at dwell frequency.
Dwell frequency : This function is used to output torque in an intended direction. It is useful in
hoisting applications to get enough torque before releasing a mechanical brake. Rated Slip frequency
is calculated by the formula shown below.

When the input power is cut off due to instant power failure, the inverter outputs
Low voltage trip (LV) to hold the output.
When the power is restored, the inverter outputs the frequency before the low
voltage trip and the voltage is increased due to PI control.
t1 : If the rise in current is greater than the preset level in H23, the rise in voltage
will stop and the frequency is decreased.
t2 : If the opposite of t1 occurs, the increase in voltage starts again and the
decrease in frequency stops.
When the frequency and voltage are restored back to the nominal level,
acceleration will continue at the frequency before trip.
Speed search is suitable operation when load inertia is great. It is highly recommended to restart
after stopping the motor when the load inertia is great.

H26 : Auto restart will become active after the H27. The H26 – [Number of Auto restart try] is reduced
by 1 when it is active. If the trip outnumbers the preset restart try, auto restart function is deactivated. If
the setting is reset via the control terminal or the STOP/RST key on the keypad, the number of auto

loss
The inverter turns off its output when the one or more of the output (U, V, W) phase is
open. The inverter detects the output current to check the phase loss of the output.
The inverter turns off its output if the DC voltage of the main circuit increases higher than
Over voltage
400 V when the motor decelerates. This fault can also occur due to a surge voltage
generated at the power supply system.
The inverter turns off its output if the DC voltage is below 180V because insufficient
Low voltage
torque or overheating of the motor can occur when the input voltage of the inverter drops.
The internal electronic thermal of the inverter determines the overheating of the motor. If
Electronic
the motor is overloaded the inverter turns off the output. The inverter cannot protect the

EMC INSTALLATION GUIDE
LG inverters are tested to meet Electromagnetic Compatibility (EMC) Directive 89/336/EEC and Low Voltage (LV)
Directive 73/23/EEC using a technical construction file. However, Conformity of the inverter with CE EMC requirements
does not guarantee an entire machine installation complies with CE EMC requirements. Many factors can influence total
machine installation compliance.
Essential Requirements for CE Compliance
Following conditions must be satisfied for LG inverters to meet the CE EMC requirements.
1. CE compatible LG inverter
2. Installing inverter in an EMC enclosure
3. Grounding enclosure and shielded parts of wire
4. Using shielded cable
5. Use it under industrial environment.
6. It is important that all lead lengths are kept as short as possible and that incoming mains and outgoing motor cables
are kept well separated.
