Max Description
Allows a selected cell to be manually faulted. Typically
used to test cell bypass.
Reset bypassed cells when the drive is in an idle state. Use
the reset function only after verifying that the problems
with the faulted cell(s) have been resolved.
Set the pole inversion type based on the cell neutral con‐
nection point. Select the cell terminal, T1 or T2, which
forms the neutral connection. This selection depends on
the terminal of cells A1, B1, and C1 that is used to form
the drive start-point neutral.
Enable software sync check of medium voltage and pre‐
charge voltage for Precharge Type 6.
15 Description: Sets the maximum phase angle permissible
between medium voltage and precharge voltage for Pre‐
charge Type 6.
10 Time delay for closing M4 to stabilize current. Maintains
the M3 contactor until timeout, then allows the state
machine to continue by closing M4.
95 Sets the voltage level to stop M2 resonance and advance
the precharge state machine.
Note: The default parameter value is 90%. Previously, the
voltage level was fixed for Type 1 and Type 2 and hard-
coded to 95%. These levels may require adjustment. The
remaining type levels remain unchanged and do not re‐
quire adjustment.
Enable input transformer pre-charge for the protection of
cells from in-rush current:
• Type 1 HV - 3CB
• Type 2 HV - 2CB
• Type 3 Parallel Drive
• Type 4 Open 1 CB
• Type 5 Open (750 V AP and 750 V AP 4Q)
• Type 6 Closed (750 V AP and 750 V AP 4Q)
Note: All types are resonant with the exception of Type 3.
10.0 Time delay between end of pre-charge and start of cell
diagnostics. For HV and 6SR4_0 cells, although pre-
charge is not used, it replaces the nominal one second
delay in cell diagnostics.
