Fire Mode forces the inverter to ignore certain faults and continues to
operate. Set output relays or Q1 (OUT-31–35 or OUT-36) to ‘27 (Fire
Mode)’ to receive the fire mode warning output signals.
Displayed when a pipe is broken during pump operation. Set output
relays or Q1 (OUT-31–35 or OUT-36) to ‘28 (Pipe Broken)’ to receive
the pipe break warning output signals.
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 output relays
or Q1 (OUT-31–35 or OUT-36) to ‘24 (Lost KPD)’ to receive the lost
keypad warning output signals.
Displayed during a level detect state. Set PRT-70 to ‘1 (warning)’ to
enable.
Displayed when the RTC battery voltage drops to (or below) 2 V. To
receive a warning output signal, set PRT-90 (Low Battery) to ‘Yes’.
Displayed when PRT-91 is set to warning and the inverter senses the
condition of a broken belt.
Displayed when the function of load tuning is not normal . Values of
‘AP2-03 and AP2-04’ are more than the values of ‘AP2-09 and AP2-10’.
Displayed when the smart copier download/upload is not normal.
Displayed when the function of Rs tuning is not normal . For example,
auto tuning is performed without wiring the motor.
Displayed when the function of Lsigma tuning is not normal . For
example, auto tuning is performed without wiring the motor.
If [DRV-05 KPD H.O.A Lock] is set to locked, message flashes for one
second when any HAND-OFF-AUTO button is pressed.
Occurs when an abnormality is detected in the cooling fan inside the
inverter 150 HP ~ 800 HP (110 kW to 500 kW).
Backspin timer is a protection function enabled when the timer (PRT-
01) is set to any value above “0”. During the set time, inverter displays
the warning message and ignores the run command signal and the fault
auto reset & restart signals. After the PRT-01 Backspin Time expires,
the inverter automatically restarts according to the reset & restart signal
status.
