*If a tunE through tunE 7 trip occurs, then after the drive is reset the drive cannot be made to run unless it is disabled via the drive enable parameter
(Pr 6.15) or the control word (Pr 6.42).
thS Motor thermistor short circuit
25
Check motor thermistor wiring
Replace motor / motor thermistor
Set Pr 7.15 (in01, 0.81) = VOLt and reset the drive to disable this function
tunE Autotune stopped before completion
18
The drive has tripped out during the autotune
The red stop key has been pressed during the autotune
tunE1* The position feedback did not change or required speed could not be reached during the inertia test (see Pr 5.12)
11
Ensure the motor is free to turn i.e. brake was released
Ensure Pr 3.26 and Pr 3.38 are set correctly
Check feedback device wiring is correct
Check feedback device coupling to motor
tunE2* Position feedback direction incorrect or motor could not be stopped during the inertia test (See Pr 5.12)
12
Check motor cable wiring is correct
Check feedback device wiring is correct
tunE3* Field flux has not decayed to zero during autotune
13 Contact the supplier of the drive
tunE4* Back emf detected during autotune
14 Check that the motor is not spinning when a static autotune is carried out
tunE5* No field current detected during autotune
15 Reset Pr 5.70 to nameplate value and re-autotune motor
tunE6* Cannot achieve ¼ rated back emf during autotune
16 Reset Pr 5.70 to nameplate value and re-autotune motor
tunE7* Rotated autotune initiated with Estimated speed selected
17 Connect a feedback device to carry out a rotating autotune
