LCD Display Type Description
Lost Command Level
Displayed when a frequency or operation command error is
detected during inverter operation by controllers other than the
keypad (e.g., using a terminal block and a communication
mode). Activate by setting PRT-
12 to any value other than ‘0’.
IO Board Trip Latch
Displayed when the I/O board or external communication card
is not connected to the inverter or there is a bad connection.
TB Trip Latch
It occurs when the control terminal block (Terminal Bolck) is
disconnected or the contact state is bad.
ParaWrite Trip Latch
Displayed when communication fails during parameter writing.
Occurs due to a control cable fault or a bad connection.
Option Trip-1 Latch
Displayed when a communication error is detected between
the inverter and the communication board. Occurs when the
communication option card is installed.
5.1.2 Warning Message
LCD Display Description
Over Load
Displayed when a motor is overloaded. Set PRT-
17 to ‘1’ to enable. Set
OUT-31
–35 or OUT-36 to ‘5 (Over Load)’ to receive the overload warning
output signals.
Under Load
Displayed when the motor is underloaded. Set PRT-
25 is to ‘1’. Set the
digital output terminal or relay (OUT-31
–35 or OUT-36) to’ 7 (Under
Load)’ to receive the underload warning output signals.
INV Over Load
Displayed when the overload time equivalent to 60% of the inverter
overheat protection (inverter IOLT) level, is accumulated. Set the digital
output terminals or relay (OUT-31
–35 or OUT-36) to ‘6 (IOL)’ to receive
the inverter overload warning output signals.
Lost Command
Lost command warning alarm occurs even with PRT-
12 set to ‘0’. The
warning alarm occurs based on the condition set at PRT-13-15. Set the
digital output terminals or relay (OUT-31
–35 or OUT-36) to ‘13 (Lost
Command
)’ to receive the lost command warning output signals.
Fan Warning
Displayed when an error is detected from the cooling fan while PRT-79 is
set to’1’. Set the digital output terminals or relay (OUT-31–35 or OUT-36)
to ‘8 (Fan Warning)’ to receive the fan warning output signals.
DB Warn %ED Displayed when the DB resistor usage rate exceeds the set value. Set
