Note: If the bypass function is selected ((p1260 > 0), then when the power unit restarts after POWER OFF, the state of
the bypass switch is evaluated. This means that after the ramp-up, it is possible to directly change into the standby
mode. This is only possible for p1267 = 0 (bypass using the control signal) and if the control command after the sys-
tem has been motor is still available (p1266). This function has a high priority than the automatic restart function
(p1210).
The bypass function can only be switched-out again (p1260 = 0) if the bypass is not active or the bypass function
has a fault.
Description: Control and feedback signals of the bypass switch.
Dependency: Refer to: p2369
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.
Note: This parameter is used to define the changeover time of the contactors. It should not be shorter than the de-magne-
tization time of the motor (p0347).
Description: Sets the delay time to switch back to converter operation for a non-synchronized bypass.
