5.3 Fault Messages
The messages below show how they will appear on the display when the drive trips. When looking at the
Fault History (P500), the
F_ will not appear in the fault message.
Fault Cause Remedy
(1)
f.AF
High Temperature fault Drive is too hot inside • Reduce drive load
• Improve cooling
f.AL
Assertion Level fault • Assertion Level switch is changed
during operation
• P120 is changed during operation
• P100 or P121 is set to a value other
than 0 and P120 does not match the
Assertion Level Switch.
• Make sure the Assertion Level switch and
P120 are both set for the type of input
devices being used, prior to setting P100
or P121.
Refer to 3.2.3 and P120.
f.bf
Personality fault Drive Hardware • Cycle Power
• Power down and install EPM with valid
data
• Reset the drive back to defaults (P199 = 3,
4) and then re-program
• If problem persists, contact factory
technical support
f.CF
Control fault An EPM has been installed that is either
blank or corrupted
f.cF
Incompatible EPM fault An EPM has been installed that contains
data from an incompatible parameter
version
f.cFT
Forced Translation fault An EPM from an old drive put in new
drive causes drive to trip F_cFT fault.
Press [M] (mode button) twice to reset
f.dbF
Dynamic Braking fault Dynamic braking resistors are
overheating • Increase active decel time
(P105, P126, P127).
• Check mains voltage and P107
f.EF
External fault • P121 = 2 and that digital input has
been opened.
• P121 = 3 and that digital input has
been closed.
• Correct the external fault condition
• Make sure digital input is set properly for
NC or NO circuit
f.F1
EPM fault EPM missing or defective Power down and replace EPM
f.F2
…
f.F12
Internal faults Contact factory technical support
f.Fnr
Control Configuration
Fault
f.FoL
TB25 (4-20 mA signal)
Threshold fault 4-20 mA signal (at TB-25) drops below
the value set in P164. • Check signal/signal wire
• Refer to parameters P163 and P164.
f.GF
OEM Defaults data fault Drive is powered up with P199 =1 and
OEM settings in the EPM are not valid.
Install an EPM containing valid OEM Defaults
data or change P199 to 0.
f.HF
High DC Bus Voltage
fault Mains voltage is too high Check mains voltage and P107
Decel time is too short, or too much
regen from motor Increase active decel time (P105, P126, P127)
or install Dynamic Braking option
f.1L
Digital Input
Configuration fault
(P121) More than one digital input set for the
same function Each setting can only be used once (except
settings 0 and 3)
Only one digital input configured for
MOP function (Up, Down) One input must be set to MOP Up, another
must be set to MOP Down
PID mode is entered with setpoint
reference and feedback source set to the
same analog signal
Change PID setpoint reference (P121…P124)
or feedback source (P201).
One of the digital inputs (P121…P124) is
set to 10 and another is set to 11…14.
Reconfigure digital inputs
One of the digital inputs (P121…P124)
is set to 11 or 12 and another is set to
13 or 14.
PID enabled in Vector Torque mode
(P200 = 1 or 2 and P300 = 5)
PID cannot be used in Vector Torque mode
