Fault Code Description Detailed Description of Fault / Possible Solutions
F01 UTS Time Limit Expired Motor did not achieve full speed before the UTS timer (P9/QST09)
expired.
Check motor for jammed or overloaded condition.
Verify that the combined kick time (P14/CFN11) and acceleration
ramp time (P8/QST08) is shorter than the UTS timer setting.
Evaluate acceleration ramp settings. The acceleration ramp settings
may be too low to permit the motor to start and achieve full speed.
If so, revise acceleration ramp settings to provide more motor
torque during starting.
Evaluate UTS timer setting and, if acceptable, increase UTS timer
setting (P9/QST09).
F02 Motor Thermal Overload Trip Check motor for mechanical failure, jammed, or overloaded
condition.
Verify the motor thermal overload parameter settings (P3/QST03
and P44-P47/PFN12-PFN16,) and motor service factor setting
(P2/QST02).
Verify that the motor FLA (P1/QST01) and CT ratio (P78/FUN03)
are correct.
If motor OL trip occurs during starting, review acceleration ramp
profile settings.
Verify that there is not an input line power quality problem or
excessive line distortion present.
F03 Slow Speed Timer Limit Expired Increase Slow Speed Time Limit (P29/CFN23)
F10 Phase Rotation Error, not ABC Input phase rotation is not ABC and Input Phase Sensitivity
parameter (P77/FUN04) is set to ABC only.
Verify correct phase rotation of input power. Correct wiring if
necessary.
Verify correct setting of Input Phase Sensitivity parameter
(P77/FUN04).
F11 Phase Rotation Error, not CBA Input phase rotation is not CBA and Input Phase Sensitivity
parameter (P77/FUN04) is set to CBA only.
Verify correct phase rotation of input power. Correct wiring if
necessary.
Verify correct setting of Input Phase Sensitivity parameter
(P77/FUN04).
F12 Low Line Frequency Line frequency below 23 Hz was detected.
Verify input line frequency.
If operating on a generator, check generator speed governor for
malfunctions.
Check input supply for open fuses or open connections.
Line power quality problem / excessive line distortion..
