(continuation of Table 70)
CODE FAULT CAUSE WHAT TO DO
0018 THERM FAIL (5210) 0306 bit 1
Drive internal fault. Thermistor
used for drive internal temperature
measurement is open or short-
circuited.
Contact your local Daikin representative.
0021 CURR MEAS (2211) 0306 bit 4
Drive internal fault. Current
measurement is out of range.
Contact your local Daikin representative.
0022 SUPPLY PHASE (3130) 0306 bit 5
Intermediate circuit DC voltage
is oscillating due to missing input
power line phase or blown fuse.
Trip occurs when DC voltage
ripple exceeds 14% of nominal DC
voltage.
Check input power line fuses.
Check for input power supply imbalance.
Check fault function parameters.
0024 OVERSPEED (7310) 0306 bit 7
Motor is turning faster than highest
allowed speed due to incorrectly set
minimum/maximum speed.
Operating range limits are set by
parameters 2007 MINIMUM FREQ
and 2008 MAXIMUM FREQ.
Check minimum/maximum frequency settings.
Check adequacy of motor braking torque.
0026 DRIVE ID (5400) 0306 bit 9 Internal drive ID fault Contact your local Daikin representative.
0027 CONFIG FILE (630F) 0306 bit 10 Internal conguration le error Contact your local Daikin representative.
0028
SERIAL 1 ERR (7510) 0306 bit 11
(programmable fault function 3018,
3019)
Fieldbus communication break
Check status of eldbus communication. See chapter Fieldbus control with
embedded eldbus, page 70.
Check fault function parameter settings.
Check connections.
Check if master can communicate.
0029 EFB CON FILE (6306) 0306 bit 12 Conguration le reading error Contact your local Daikin representative.
0030 FORCE TRIP (FF90) 0306 bit 13
Trip command received from
eldbus
See appropriate communication module manual.
0031 EFB 1 (FF92) 0307 bit 0
Error from the embedded eldbus
(EFB) protocol application. The
meaning is protocol dependent.
See chapter Fieldbus control with embedded eldbus, page 70.0032 EFB 2 (FF93) 0307 bit 1
0033 EFB 3(FF94) 0307 bit 2
0034 MOTOR PHASE (FF56) 0306 bit 14
Motor circuit fault due to missing
motor phase or motor thermistor
relay (used in motor temperature
measurement) fault.
Check motor and motor cable.
Check motor thermistor relay (if used).
0035
OUTP WIRING (FF95) 0306 bit 15
(programmable fault function 3023)
Incorrect input power and motor
cable connection (i.e. input power
cable is connected to drive motor
connection).
The fault can be erroneously
declared if the input power is a
delta grounded system and the
motor cable capacitance is large.
This fault can be disabled using
parameter 3023 WIRING FAULT.
Check input power connections.
Check fault function parameters.
0036
INCOMPATIBLE SW (630F)
0307 bit 3
Loaded software is not compatible. Contact your local Daikin representative.
0038
USER LOAD CURVE (FF6B)
0307 bit 4
Condition dened by 3701 USER
LOAD C MODE has been valid
longer than the time set by 3703
USER LOAD C TIME.
See parameter Group 37: User Load Curve, page 61.
0039
UNKNOWN EXTENSION (7086)
0307 bit 5
Option module not supported by
the drive rmware is connected to
the drive.
Check connections.
0040
INLET VERY LOW (8A81)
0307 bit 6
Pressure at pump/fan inlet too low
Check for a closed valve on the inlet side of the pump/fan.
Check piping for leaks. See parameter Group 44: Pump Protection.
0041
OUTLET VERY HIGH (8A83)
0307 bit 7
Pressure at pump/fan outlet too
high
Check piping for blocks. See parameter Group 44: Pump Protection
0042 INLET LOW (8A80) 0307 bit 8 Pressure at pump/fan inlet too low
Check for a closed valve on the inlet side of the pump/fan.
Check piping for leaks. See parameter Group 44: Pump Protection.
0043 OUTLET HIGH (8A82) 0307 bit 9
Pressure at pump/fan outlet too
high
Check piping for blocks. See parameter Group 44: Pump Protection.
