Activation of the braking transistor function
To be able to use the braking transistor, the function must be activated with
parameter "is30 braking transistor function".

Destruction of the drive controller
If the error "errOr GTr7 always ON" occurs, the current con-
sumption is switched off internally via the mains input bridge of
the Ac supply.
► The drive controller must be galvanically isolated from the supply
mains within 5 minutes!
