Vector control
4.25 Bypass
Example
After activating the bypass function without synchronization (p1260 = 3) the following
parameters still have to be set:

Parameter settings for non-synchronized bypass function with overlap
Description
Setting of the dead time for non-synchronized bypass
Setting of the delay time to switch back to converter operation for non-
synchronized bypass
Setting of the delay time to switch to line operation for non-synchronized bypass
Setting of the speed threshold for activating the bypass (for p1267.1 = 1)
Setting of the signal source for the control command to the bypass
(for p1267.0 = 1)
Trigger signal setting for bypass function
Setting of the signal source for the feedback signal
"synchronization completed"
Setting of the signal source for the feedback signal of contactor K1
Setting of the signal source for the feedback signal of contactor K2
The internal voltages are used for synchronization.
Synchronizer activation is triggered by the bypass function.
