Bypass control command
Flying restart must be activated for the bypass function (p1200 = 1 or 4).
Following bypass functions are possible: Bypass function when activating via a control signal (p1267.0 = 1). Bypass function depending on the speed (p1267.1 = 1).
Contactors K1 and K2 must be interlocked so that they cannot close at the same time. In order to
prevent line contactor K2 from inadvertently closing, K2 should be closed via digital output DO 2
that is not preassigned.
