Lỗi biến tần LS IS

Keypad Display Protective
Function
Description
LCD 7-Segment
Over Current 1 OC1 Over Current
Protection
The inverter turns off its output when the output current of the inverter flows
more than 200% of the inverter rated current.
Ground Fault GF Ground Fault
Protection
The inverter turns off its output when a ground fault occurs and the ground fault
current is more than the internal setting value of the inverter. Over current trip
function may protect the inverter when a ground fault occurs due to a low
ground fault resistance.
Over Voltage OV Over voltage
protection
The inverter turns off its output if the DC voltage of the main circuit increases
higher than the rated value when the motor decelerates or when regenerative
energy flows back to the inverter due to a regenerative load. This fault can also
occur due to a surge voltage generated at the power supply system.
Over Load OLT Current Limit
Protection
(Overload
Protection)
The inverter turns off its output if the output current of the inverter flows at
180% of the inverter rated current for more than the current limit time (S/W).
Fuse Open FUSE Fuse Open The inverter turns off its output by opening the fuse when something is wrong
with the main circuit IGBT to protect the wiring from being damaged from short
currents.
Over Heat OH Heat Sink
Over Heat
The inverter turns off its output if the heat sink over heats due to a damaged
cooling fan or an alien substance in the cooling fan by detecting the
temperature of the heat sink.
E-Thermal ETH Electronic Thermal The internal electronic thermal of the inverter determines the over heating of the
motor. If the motor is overloaded the inverter turns off the output. The inverter
cannot protect the motor when driving a multi-pole motor or when driving
multiple motors, so consider thermal relays or other thermal protective devices
for each motor.
Overload capacity: 150% for 1 min
External-A EXTA External fault A Use this function if the user needs to turn off the output by an external fault
signal. (Normal Open Contact)
External-B EXTB External fault B Use this function if the user needs to turn off the output by an external fault
signal. (Normal Close Contact)
Low Voltage LV Low Voltage
Protection
The inverter turns off its output if the DC voltage is below the detection level
because insufficient torque or over heating of the motor can occurs when the
input voltage of the inverter drops.
Over Current 2 OC2 IGBT Short The inverter turns off the output if an IGBT short through or an output short
occurs.
Phase Open PO Output Phase
open
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 open
of the output.
BX BX BX Protection
(Instant Cut Off)
Used for the emergency stop of the inverter. The inverter instantly turns off the
output when the BX terminal is turned ON, and returns to regular operation
when the BX terminal is turned OFF. Take caution when using this function.
Option (**) OPT Option Fault Fault at the internal option of the inverter.
HW-Diag HW Inverter H/W
Fault
A fault signal is output when an error occurs to the control circuitry of the
inverter. There are the Wdog error, the EEP error, and the ADC Offset for this
fault
COM Error
CPU Error
Err Communication Error This fault is displayed when the inverter cannot communicate with the keypad.

Operating Method
when the
Frequency
Reference is Lost
According to the I/O-48 [Operating Method when the Frequency Reference is
Lost] setting, there are three modes: continue operation, decelerate and stop,
and free run,
LOP: Displayed when option frequency reference is lost (DPRAM time out)
LOR: Displayed when option frequency reference is lost (Communication
network fault)
LOV: Displayed when ‘V1’analog frequency reference is lost.
LOI: Displayed when ‘I‘analog frequency reference is lost.
LOX: Displayed when sun-board (V2, ENC) analog frequency reference is lost.
Inv. OLT IOLT Inverter Overload The inverter turns off its output when the output current of the inverter flows
more than the rated level (150% for 1 minute, 200% for 0.5 seconds).
NTC open NTC Thermal Sensor
Opened
Inverter uses NC thermal sensor for detecting heat sink temperature. If this
message is displayed, the thermal sensor wire may be cut. (Inverter keeps
operating)
Over Speed OSPD Overspeed Inverter shuts off its output when a motor rotates at the frequency exceeding 20
Hz of its max speed.
MC Fail MCF M/C Fail It is displayed when input power is not applied or M/C inside the inverter
malfunctions.
