CORRECTIVE ACTION
Check the motor load. Reducing it may prevent the safety
switch cutting in.
Check that the heat constant value is long enough (P71). Check
that the safety heat curve suits the motor type and change the
curve if necessary (C33).
Check if the LogicLab slow task duration is greater than 500
ms and try to reduce this execution time
Try to reduce the LogicLab fast task execution time under
admitted limit.
Please refer to the specific documentation.
Reload the application using VFDNav
In a transient state, the speed reading has exceeded the
permitted limit. Adjust the speed regulator gains or raise the
limit in P51.
Note: in case of A3.0 alarm, control board (for major safety)
removes enable to the precharge card,
so capacitor bank discharged and alarm AA0 appears.
Undervoltage may occur when the mains transformer is not
are started up on the same line.
Try to stabilise the line by taking appropriate measures. If
necessary, enable the BUS support function for mains failure
(C34=1). This however can only help motors with light loads.
An overvoltage in the mains may also trigger the safety
switch.
