This section explains troubleshooting
fault trips and other common faults.
If problems are not solved, please
contact your vendor or LSIS.
This section provides information on
how to maintain the inverters on a
regular basis for different time
periods.
When there is a problem in the
inverter, please check the
input/output module. This is the basic
method to check the hardware.
This section covers check points
when there is a problem in the
inverter.
Then check the parameter settings
using basic operations and the trip

Safety Information
Read and follow all safety instructions in this manual precisely to avoid unsafe operating conditions,
property damage, personal injury, or death.
Safety symbols in this manual
Danger
Indicates an imminently hazardous situation which, if not avoided, will result in severe injury or
death.
Warning
Indicates a potentially hazardous situation which, if not avoided, could result in injury or death.
Caution
Indicates a potentially hazardous situation that, if not avoided, could result in minor injury
or property damage.
Safety information
Danger
Do not open the cover of the equipment while it is on or operating. Likewise, do not operate
the inverter while the cover is open. Exposure of high voltage terminals or charging are to the
external environment may cause an electric shock. Do not remove any covers or touch the
internal circuit boards (PCBs) or electrical contacts on the product when the power is on or
during operation. Doing so may cause serious injury, death or serious property damage.
Do not open the cover of the equipment even when the power supply to the inverter has been
turned off unless it is necessary for maintenance or regular inspection. Opening the cover
may lead to an electric shock even when the power supply is off.
The equipment may hold charge long after the power supply has been turned off. Use a multi-
meter to make sure that there is no voltage before working on the inverter, motor, or motor
cable.

6
Warning
This equipment must be grounded for safe and proper operation.
Do not supply power to a faulty inverter. If you find that the inverter is faulty, disconnect the
power supply and have the Inverter repaired.
The Inverter becomes hot during operation.Avoid touching the Inverter until it has cooled
down to avoid burns.
Do not allow external objects, such as screws, metal chips, debris, water, or oil to get inside
the Inverter. Allowing external substances inside the Inverter may cause the Inverter to
malfunction or ignite fire.
Do not operate the Inverter with wet hands. Doing so may cause electric shock.
Caution
Do not modify the interior structure/components of the Inverter. Doing so will void the
warranty.
The Inverter is designed for 3-phase motor operation. Do not use the Inverter to operate 3-
phase motor.
Do not place heavy objects on top of electric cables. Doing so may damage the cable and
cause an electric shock.

Adjust motor operational noise by changing the carrier frequency settings. Power transistors (IGBT)
in the Inverter generate and supply high frequency switching voltage to the motor. Carrier
frequency is the switching speed in this process. If the carrier frequency is set high, it reduces
operational noise from the motor. If the carrier frequency is set low, it increases operational noise
from the motor.
Below demonstrates the advantages and disadvantages according to the sound of the Inverter
during operation.

2 Troubleshooting
This chapter explains how to troubleshoot when the protective functions, fault trips, warning signals,
or a fault occurs while operating the inverter. If the inverter does not work as expected after
following the suggested troubleshooting steps, please contact the LSIS Customer Service Center.
2.1 Trips and Warnings
The Inverter will stop operating or send out a warning signal when it detected a fault. The keypad
will show brief information of the trip and warning signal. If the model is using the LCD keypad, the
LCD will show detailed information.
Up to 5 failures can be saved and can be found in code Pr.90. When there are more than 2 trips,
the keypad display will show in the order of priority. The LCD will show in the order the fault
occurred. Failure history is saved by either resetting the Inverter or when the inverter turns off due
to low voltage failure. If the number of failures exceeds 5, the last 5 messages will be deleted
automatically.
The following is how the fault conditions are categorized:
•Level: After the fault is corrected, the trip or warning signal disappears. The fault is not saved
in the fault history.
•Latch: After the fault is corrected, the trip or warning signal disappears once the Inverter is
reset.
•Fatal: After the fault is corrected, the trip or warning signal disappears when conducted the
following procedure. Turn off the Inverter and wait until the charge indicator light goes off. Then,
turn on the Inverter. If the Inverter still failed, please contact the supplier or LSIS Customer
Service Center.
