(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 LS 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.

l

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.

l

Install the inverter using screws or bolts to insure the inverter is firmly fastened.

Connection of peripheral devices to the inverter

The following devices are required to operate the inverter. Proper peripheral devices must be selected and correct
connections made to ensure proper operation. An incorrectly applied or installed inverter can result in system malfunction
or reduction in product life as well as component damage. You must read and understand this manual thoroughly before
proceeding.

Use the power supply within the permissible
AC Supply Source

range of inverter input power rating. (See
14.Specifications)

MCCB or Earth leakage

Select circuit breakers with care. A large inrush

circuit breaker (ELB)

current may flow in the inverter at power on.

Install it if necessary. When installed, do not use it
Magnetic Contactor

for the purpose of starting or stopping. Otherwise,
it could lead to reduction in product life.

The reactors must be used when the power factor
AC/DC Reactors

is to be improved or the inverter is installed near a
large power supply system (1000kVA or more and
wiring distance within 10m)

To operate the inverter with high performance for
a long time, install the inverter in a proper place in
Installation and wiring

the correct direction and with proper clearances.
Incorrect terminal wiring could result in the
equipment damage.

Do not connect a power factor capacitor, surge
To motor

suppressor or radio noise filter to the output side
of the inverter.

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.

4

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.

4

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.

The inverter turns off its output if the DC voltage is below 180V because insufficient
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
the motor is overloaded the inverter turns off the output. The inverter cannot protect the
motor when driving a motor having more than 4 poles or multi motors.

EMC INSTALLATION GUIDE
LS 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 LS inverters to meet the CE EMC requirements.
1. CE compatible LS 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.
