Bypass function when activating via a control signal (p1267.0 = 1)
The state of the bypass contactors is evaluated when the inverter is switched on. If the
automatic restart function is active (p1210 = 4) and an ON command (r0054.0 = 1) as well as
the bypass signal (p1266 = 1) are still present at power up, then after power up, the inverter
goes into the "ready and bypass" state (r899.0 = 1 and r0046.25 = 1) and the motor
continues to run directly connected to the line supply.
