Page 184: Cell Bypass
Operating the Control 7.4 Cell Bypass Cell Bypass 7.4.1 Fast Bypass (U11) Fast bypass is a feature that limits the interruption of torque to a process by less than ½ second if a cell failure is detected. This helps to prevent operational down-time as a small interruption in output torque of a medium voltage drive can cause a process to stop.
Page 185: Forced Bypass - Non-Faulted Cells
Two levels of security must be used to activate this feature. • The Factory or Siemens authorized personnel must have access to allow it to work at both Idle and Run drive states. Since this could cause a problem while running, it is not available for general purpose.

Operating the Control 7.4 Cell Bypass Figure 7-2 Typical Power Cell with Bypass Contactor Once the control detects that a cell has failed, it sends a command to close the appropriate contactor. Closing the contactor simultaneously disconnects the cell output from the circuit and connects the two adjacent cells together.

The cells, represented by circles, are shown as simple voltage sources. 15 cell drive in which no cells are bypassed The following figure shows a 15 cell drive with no cells bypassed.
Page 189 Operating the Control 7.4 Cell Bypass Drive output rebalanced by bypassing functional cells (not using neutral shift) One solution is to bypass an equal number of cells in all three phases, even though some may not have failed. This method prevents imbalance but sacrifices voltage capability. The example below shows a 15 cell drive after bypass of two cells in all phases to restore balance.
Page 190 Operating the Control 7.4 Cell Bypass Figure 7-6 Drive Output rebalanced using neutral shift This neutral shift approach can be applied to more extreme situations. Using neutral shift after loss of three cells This example shows a 15 cell drive: five cells remain in phase A; one cell has failed in phase B; two cells have failed in phase C.
Page 191 Operating the Control 7.4 Cell Bypass Using neutral shift after loss of five cells This example shows a 15 cell drive: five cells remain in phase A; two cells have failed in phase B; three cells have failed in phase C. Without neutral shift, one functional cell would be bypassed in phase B, and three functional cells would be bypassed in phase A.
Page 192 Operating the Control 7.4 Cell Bypass Available voltage after failure with and without neutral shift The following graph compares the available voltage after a failure with and without using neutral shift. In many cases, the extra voltage available with neutral shift will determine whether or not a cell failure can be tolerated.
Page 193 Operating the Control 7.4 Cell Bypass If after cell bypass, the drive has six cells operational in phase A, five cells in phase B, and four cells in phase C, then the maximum voltage that the drive can produce with neutral shift from the above formula is 5.53 kV: Vout_bypass = 7370 * (2 * 6 - 3) / (2 * 6) = 5.53 kV With X = 1 + 2 = 3, because 2 cells in phase C and 1 cell in phase B are bypassed.

There are two possible implementations of paralleling drives with NXGpro control.
Page 319 Advanced Operating Functions 8.20 Paralleling Multiple Drives The drive requires the use of a PLC to provide average I to each drive over a network. This is used to modify the flux demand through the flux droop scaler. Since flux is provided through induction from the stator to the rotor which is fed by both drives, flux feedback to each drive must be precise to control the contribution of each drive.

Advanced Operating Functions 8.24 Long Cable Applications 8.24 Long Cable Applications 8.24.1 Cable Inductance Compensation Long cable applications present a challenge as the cables become a significant contribution to the overall load impedance. Compensation for cable inductance affects the output voltage during transient conditions of current based on the output fundamental frequency.
