9.1.2 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 the
detection level at PRT-66.
Fire Mode
When there is a fire, Fire Mode forces the inverter to ignore certain fault trips
and continue to operate. Set the digital output terminals or relay (OUT-31–35
or OUT-36) to ‘27 (Fire Mode)’ to receive the fire mode warning output signals.
Pipe Broken
Displayed when a pipe is broken during pump operation. Set the digital
output terminals or relay (OUT-31–35 or OUT-36) to ‘28 (Pipe Broken)’ to
receive the pipe break warning output signals.
Lost Keypad
Displayed when a communication error occurs between the keypad and the
inverter, when PRT-11 (Lost KPD Mode) is set to any other value than ‘0’, and a
run command is given from the keypad. Set the digital output terminals or
relay (OUT-31–35 or OUT-36) to ‘24 (Lost KPD)’ to receive the lost keypad
warning output signals.
Level Detect Displayed during a level detect state. Set PRT-70 to ‘1 (warning)’ to enable.
CAP. Warning Displayed when capacitor life expectancy level goes below the level set by the
