[SCR Diag Status]
Bits 0…11 indicate which SCR or SCR pair is in error. The type of error is indicated in bits 13…15. Only one type of error is shown at a time. The
precedence of errors is “Shorted SCR,” “OpenSCR Trip,” and “OpenSCR Warn.” Note that “OpenSCR Warn” is independent from a SCR trip configured as an
alarm. This parameter is only active when bit 0 “OpenSCR Tst” or bit 1 “ShortSCR Tst” of Par 213 is set to 1 “Enabled.” The SCR numbering shown is
SCR1…SCR6 for the forward power bridge and SCR11…SCR16 for the reverse bridge (regenerative drives only). In the standard drive, SCRx corresponds
to the SCR package labelled KGx and SCR1x to the package labelled KG0x. See the appropriate PowerFlex DC Drive Hardware Service Manual for your drive
frame size for instructions on replacing SCR modules. For frame A drives, see
. For frame B drives
For frame C drives, see
or frame D drives
.
Note: This parameter was added for firmware version 6.001.
