3.6.2.2 General fault reset (Pn.15)

Functional description „Pn.15 > 0“

a)Thersterrorisresetafterawaitingperiodofapprox.4seconds.

b) Any further errors that occur within the next hour, will also be reset at the end of the waiting period.

Iftheerrorcriterionisreachedtheerrornumber41isdisplayedinru.00.(Operator:E.FrLr).

If there are more errors than adjusted in Pn.15 within this hour, the unit can only be reset manually via terminal

strip or via "BUS".

Manual resetting of a fault resets also the "time grid". That means, the next error will automatically reset again

after the waiting period.

3.6.3 Automatic Restart

With the automatic restart, the COMBIVERT resets the error automatically or clears it automatically by a mal-

function.

The automatic restart only makes sense if the error can be expected based on the application. Normally, the

causeoftheerrormustrstbeinvestigatedandeliminatedbeforethedrivecanbeputbackinoperationby

executing the reset.

Therefore, it must be selected after which errors an automatic restart should be executed

Because of the independent starting of the machine safety measures must be provided for

operating personnel and machine!
