TnF01
Line-to Line Resistance
Error
The line-to-line resistance in
Auto-Tuning is negative or limited by
the upper the lower limit
Check and correct motor wiring
TnF02
Stationary Auto-Tuning
Error
The voltage or current is too large
during stationary Auto-Tuning
Make sure the data entered in t1-03 to t1-05 is
the same as the information showed on the
motor nameplate
Check and correct motor wiring
TnF03
Rotational Auto-Tuning
Error
The voltage or current is too large
during rotational Auto-Tuning
Make sure the data entered in t1-03 to t1-05 is
the same as the information showed on the
motor nameplate
Check and correct motor wiring
Perform Auto-Tuning after disconnect the
motor from the machinery
TnF07
Motor Data Error
t5-05 and t1-07 setting incorrect
Make sure the data entered to t1-05 and t1-07
is the same as the information showed on the
motor nameplate.
Reset the parameters.
TnF08
Detection of PM rotor
initial position error
During the detection of the
permanent magnet motor, the
motor rotor is rotated by an external
force.
The initial position detection value is
abnormal.
Keep the motor stationary when detecting,
and avoid external force to make the motor
rotate.
TnF09
PM Motor Inductance
Error
The voltage or current is too large or
the inductance value is error during
inductance Auto-Tuning
Make sure the parameter is properly set
according to the motor nameplate.
Reset T2 parameters
TnF10
PM Motor Back EMF
Error
The voltage or current is too large or
the value is error during back EMF
Auto-Tuning
Make sure the parameter is properly set
according to the motor nameplate.
Reset T2 parameters
