Proof Test Status
UINT8 RO
Default: 0
Enum
Proof Test Status. 0: Proof test is idle (not triggered), 1: Proof test is
running, 2: Proof test passed, 3: Proof test failed.
401
Ground Fault Current Scale
Factor
UINT16 RO
Default: 1000
Ground Fault Current Fractional Scale Factor
Divide integer ground current value by this value to convert the value to
Amps.
402
Ground Current Percent
UINT16 RO
Units: Scaled Amps
Ground current percent of trip threshold
Ground current percent of trip threshold
403
GFM CT Diagnostic Status
UINT8 RO
Enum
CT input connection diagnostic status passed to BCM: Disabled, OK,
High-Z, Low-Z. GFM CT connection diagnostic status.
500
FLA Active Motor Scaled
UINT16 RO
Default: 101 (RW)
Range: 1 to 65535 (RW)
Units: scaled A
Active Overload FLA (Nominal Current) Scaled is a read only parameter
indicating the active FLA. For example, if the application has two
windings (and two FLA settings), this parameter will indicate the currently
active motor winding setting. Scaled by parameter “I Scale Factor”.
501
Rated Speed RPM Active
UINT16 RO
Default: 1750
Range: 300 to 3600
Units: RPM
RPM nameplate rating of the active motor winding.
502
Rated HP Active Scaled
UINT32 RO
Units: HPx100
HP nameplate rating of the active motor winding. This value is scaled by
0.01. For example if the motor is rated at 123.25 HP then this parameter
should contain 12325.
504
Rated Watts Active
UINT32 RO
Default: 14914
Range: 10 to 3728500
Units: W
Watts nameplate rating of the active motor winding.
506
Active Control Source
UINT8 RO
Enum
The control source that is currently active: User Interface, Fieldbus or
Fieldwire
