CAUSE
Drive internal fault . Thermistor
used for drive internal temperature
measurement is open or short-
circuited .
Drive internal fault . Current
measurement is out of range .
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 .
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 .
Internal drive ID fault
Internal configuration file error
Fieldbus communication break
Configuration file reading error
Trip command received from
fieldbus
Error from the embedded fieldbus
(EFB) protocol application . The
meaning is protocol dependent .
Motor circuit fault due to missing
motor phase or motor thermistor
relay (used in motor temperature
measurement) fault .
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 .
Loaded software is not compatible .
Condition defined by 3701 USER
LOAD C MODE has been valid
longer than the time set by 3703
USER LOAD C TIME .
Option module not supported by
the drive firmware is connected to
the drive .
Pressure at pump/fan inlet too low
Pressure at pump/fan outlet too
high
Pressure at pump/fan inlet too low
Pressure at pump/fan outlet too
high

WHAT TO DO
Contact your local Daikin representative .
Contact your local Daikin representative .
Check input power line fuses .
Check for input power supply imbalance .
Check fault function parameters .
Check minimum/maximum frequency settings .
Check adequacy of motor braking torque .
Contact your local Daikin representative .
Contact your local Daikin representative .
Check status of fieldbus communication. See chapter Fieldbus control with
embedded fieldbus, page 70 .
Check fault function parameter settings .
Check connections .
Check if master can communicate .
Contact your local Daikin representative .
See appropriate communication module manual .
See chapter Fieldbus control with embedded fieldbus, page 70 .
Check motor and motor cable .
Check motor thermistor relay (if used) .
Check input power connections .
Check fault function parameters .
Contact your local Daikin representative .
See parameter Group 37: User Load Curve, page 61 .
Check connections .
Check for a closed valve on the inlet side of the pump/fan .
Check piping for leaks . See parameter Group 44: Pump Protection .
Check piping for blocks . See parameter Group 44: Pump Protection
