Table 40 - Fault Cross Reference by Number
STune CurLimit 59 2 One of the following has occurred:
• The value of Par 1048
[Autotune Cur Lim] for auto tuning
the speed regulator is set too high.
Decrease the value of Par 1048 [Autotune Cur Lim] and repeat the
auto tune procedure.
• Par 107
[Speed Zero Level] and/or 108 [Speed Zero Delay]
is set too high.
Set Pars 107 and 108 to their default values when performing the
Speed Loop Autotuning function.
STune FrictionLo 60 2 The friction value attained during the auto tuning procedure
is zero or lower than the control precision limit.
Decrease the value of Par 1048
[Autotune Cur Lim] and repeat the
auto tune procedure.
STune LoadHi 58 2 One of the following has occurred:
• The loading torque value is too high at zero speed to
complete the speed regulator auto tuning procedure.
Decrease the load torque, where applicable, and repeat the auto
tune procedure.
• Par 107
[Speed Zero Level] and/or 108 [Speed Zero Delay]
is set too high.
Set Pars 107 and 108 to their default values when performing the
Speed Loop Autotuning function.
STune Overspeed 56 2 The measured motor speed is too high during the speed
regulator auto tuning procedure.
Decrease the value of Par 1048
[Autotune Cur Lim] and repeat the
auto tune procedure.
STune Stalled 57 2 The drive stalled during the speed regulator auto tuning
procedure.
Increase the value of Par 1048
[Autotune Cur Lim] and repeat the
auto tune procedure.
STune Timeout 61 2 The speed regulator auto tuning procedure did not complete
within the available time or the current regulator auto tuning
procedure did not complete within 15 minutes.
Verify the value in Par 1048
[Autotune Cur Lim]. If this value is set to
low, the motor will not be able to reach a maximum speed of 33%
of the lower of the values in Par 45 [Max Ref Speed] or Par 3 [Max
Speed Fwd] or Par 4 [Max Speed Rev] and not be able to complete
the test. Set these values appropriately and repeat the auto tuning
procedure.
Sustained Curr 70 2 One of the following has occurred:
• The motor CEMF is too high or the line voltage is too low
• A current bridge change command has not completed
within 1 second
• Check the line voltage and frequency.
• Check the motor brushes and connections.
• Check the Main and DB Contactor connections if present.
• Verify that there are no overhauling loads present.
