Pump VFD Controller
between terminal 18 or 19 (digital input PNP only) and terminal
50. If a KTY sensor is used, check for correct connection
between terminal 54 and 55.
WARNING/ALARM 13 - Over Current
The inverter peak current limit (approx. 200% of the rated
current) is exceeded. The warning will last approx. 8-12 sec,
then the inverter trips and issues an alarm. Turn off the inverter
and check if the motor shaft can be turned and if the motor size
matches the inverter.
ALARM 14 - Earth fault
There is a discharge from the output phases to earth, either in
the cable between the inverter and the motor or in the motor
itself. Turn off the inverter and remove the earth fault.
ALARM 16 - Short-circuit
There is short-circuiting in the motor or on the motor terminals.
Turn off the inverter and remove the short-circuit.
WARNING 23 - Internal fans
External fans have failed due to defective hardware or fans not
mounted.
WARNING/ALARM 29 - Drive over temperature
If the enclosure is IP00, IP20/Nema1 or IP21/TYPE 1, the
cutout temperature of the heat-sink is 95°C +5°C. The
temperature fault cannot be reset until the temperature
of the heatsink is below 70°C. The fault could be Ambient
temperature too high or too long motor cable.
ALARM 30 - Motor phase U missing
Motor phase U between the frequency converter and the motor
is missing. Turn off the frequency converter and check motor
phase U.
ALARM 31 - Motor phase V missing
Motor phase V between the inverter and the motor is missing.
Turn off the inverter and check motor phase V.
ALARM 32 - Motor phase W missing
Motor phase W between the inverter and the motor is missing.
Turn off the frequency converter and check motor phase W.
ALARM 33 - Inrush fault
Too many power ups have occurred within a short time period.
WARNING/ALARM 36 - Mains failure
This warning/alarm is only active if the supply voltage to the
inverter is lost and par. 14-10 Mains Failure is NOT set to OFF.
Possible correction check the fuses to the frequency converter
WARNING/ALARM 37 - Phase Imbalance
There is a current imbalance between the power units.
WARNING 49 - Speed limit
The speed has been limited by range in par. 4-11 Motor Speed
Low Limit [RPM] and par. 4-13 Motor Speed High Limit [RPM].
ALARM 50 - AMA calibration failed
Contact Daikin Applied service.
ALARM 51 - AMA check Unom and Inom
The setting of motor voltage, motor current, and motor power is
presumably wrong. Check the settings.
WARNING 59 - Current limit
The current is higher than the value in par. 4-18 Current Limit.
WARNING 60 - External Interlock
External Interlock has been activated. To resume normal
operation, apply 24 V DC to the terminal programmed for
External Interlock and reset the inverter (via Bus, Digital I/O or
by pressing [Reset]).
WARNING 66 - Heatsink Temperature Low
The heat sink temperature is measured as 0 °C. This could
indicate that the temperature sensor is defective and thus the
fan speed is increased to the maximum in case the power part
or control card is very hot. If the temperature is below 15 °C
the warning will be present.
ALARM 68 - Safe Stop
Safe Stop has been activated. To resume normal operation,
apply 24 VDC to terminal 37 then send a Reset signal (via Bus,
Digital I/O or by pressing [Reset]).
ALARM 69 - Pwr . Card Temp
Power card over temperature.
ALARM 92 - No Flow
A no load situation has been detected for the system. See
parameter group 22-2*.
ALARM 93 - Dry Pump
A no flow and high speed indicates that the pump has run dry.
See parameter group 22-2*.
ALARM 96 - Start Delayed
Start of the motor has been delayed due to short cycle
protection is active. See parameter group 22-7*.
