Behavior with delay times
T1 and T2
If the control variable deviates from the set bandwidth for a long period
, a control impulse is output to the motor-drive unit after the set delay time
T1 . If the control variable is still outside the bandwidth, delay time T2
starts to count down. Once delay time T2 is complete, a control impulse is
again issued to the motor-drive unit for the tap change to return to the tol-
erance bandwidth.

1 Upper limit of bandwidth 4 Set delay times T1 and T2.
2 Desired value 5 Control variable measured value
3 Lower limit of bandwidth 6 Bandwidth range
A Control variable is outside of the
bandwidth. Delay time T1 starts.
B Delay time T1 complete. Tap
change triggered.
C Delay time T2 complete. Tap
change triggered.
