B-170 1756-DMD30 Specific Information
Parameter 2125 [Interlock Code]
The PMI processor performs interlock tests in response to parameter
2100 [Drive Ctrl Word]. If any of the diagnostics fail the PMI
processor sets the bit in parameter 2125 [Interlock Code] that
corresponds to the first failed diagnostic. The bit stays latched until
bit 19 [Clear Fault] of parameter 152 [Applied LogicCmd] or bit 19 [Clr
Drv Wrn] of parameter 166 [Motor Ctrl CÌmd] is set. Refer to Reliance
Electric publication S-3001-1, Distributed Power System SD3000 Drive
Diagnostics, Troubleshooting and Start-Up Guidelines, for information
about the interlock diagnostics.
Bit Fault Name Fault Description
0 Bad CML Req More than one incompatible CML operating mode has been
requested at a time in parameter 166 [Motor Ctrl Cmmd].
The following operating modes are mutually exclusive:
• Armature Alpha Test
• Armature Identification Test
• CML Run
This bit is also set if you have attempted to restart the drive
without resetting the appropriate command bits from
parameter 166. Note that the bits in register 166 are
edge-sensitive.
1 A Par NotLod Armature configuration parameters have not been
downloaded into the PMI module from the Drive Module.
2 A Gns NotLod Armature configuration parameters have not been
downloaded into the PMI module from the Dive Module.
3 A Flt Rst Rq The CML Faults Need to be Reset bit is set if previous
armature faults (parameter 2122 [MC Faults]) have not been
cleared.
4 RPI Missing The run permissive input on the Resolver & Drive l/O module
is not on.
5 Fld Not Rdy The single-phase field is not on. Note that the CML can-not
be executed if the field is not on.
6 Fld NotAlwd The single-phase field has been requested when the
armature identification test or the armature alpha test is
running.
7 M-Con NotCls The M-Contactor did not close at the expected time.
8 Bad FML Req More than one incompatible Field operating mode is
requested at a time in parameter 166 [Motor Ctrl Cmmd].
The following operating modes are mutually exclusive:
• Field Alpha Test
• Field Identification Test
• Field Run
This bit is also set if you have attempted to restart the drive
without resetting the appropriate command bits from
parameter 166. Note that the bits in register 166 are
edge-sensitive.
