Description: Sets the configuration for the bypass function.
Value: 0: Bypass deactivated
3: Bypass without synchronization
Dependency: The "Bypass" function is only available for induction motors.
Note: When the converter is switched on, the state of the bridging contactor is evaluated.
If the automatic restart is active (p1210 = 4) and both an ON command (r0054.0 = 1) and the bypass signal (p1266 =
1, configuration p1267.0 = 1) are still present during power up, the converter goes into "ready for operation and
bypass" state (r0899.0 = 1 and r0046.25 = 1) after power up, and the motor continues to run directly on the line.
The "bypass" function can only be switched off again (p1260 = 0) if the bypass is not active or the bypass function
has a fault.
The "flying restart" function must be activated (p1200).
Description: Control and feedback signals of the bypass switch.
Dependency: The "Bypass" function is only available for induction motors.
Note: Control bits 0 and 1 should be interconnected to the signal outputs via which the switches in the motor feeder cables
should be controlled. These should be selected/dimensioned for switching under load.
Description: Sets the dead time for non-synchronized bypass.
Dependency: The "Bypass" function is only available for induction motors.
Note: This parameter is used to define the changeover time of the contactors. It should not be shorter than the de-
magnetizing time of the motor (p0347).
The total changeover time for the bypass is based on the total of p1262 plus the OFF time for the relevant switch
(p1274[x]).
