Access Field Description
(R/W)
Estimated rotor angle (electrical), which is used for synchronous
R
frame to stationary frame transformation. The scaling is 4096 = 2PI.
The range is 0 – 4095.
This is a drive control status flag which indicates that the drive has
R
switched from open-loop to closed-loop operation. The switch over is
done during drive start-up (initial speed ramping)
This is a drive control status flag indicating that the drive has failed to
R
start due to various reasons (for instance: shaft jam). The start-stop
sequencer uses this bit and parameter NumRetry to determine
whether a start-up retry should be activated.
This is a status flag indicating that the drive has finished obtaining the
R
initial rotor angle (parking) for motor startup. During drive start-up, the
first start-up stage is parking stage.
Synchronous or rotating frame direct and quadrature current values
R
in 2’s complement representation. The full scale current values range
from –16384 to 16383. (Scaling: 4095 = rated motor current)
Synchronous or rotating frame quadrature current command values
R
in 2’s complement representation. The full scale current values range
from –16384 to 16383.
R
Estimated motor flux value. Scaling is 5000 = rated motor flux.
Stationary frame current. Scaling is platform dependent (current
R
shunt resistor). Drive commissioning tool (Spreadsheet) provides
the scaling of I_Alpha (AiBi scale).
Stationary frame Alpha voltage. This voltage is constructed by dc bus
R
voltage and modulation index in the Stationary frame. The scaling is
platform dependent.
FocDiagnosticData Read Register Field Definitions
4.3.4 FaultStatus Register Group (Read Registers)
The Fault Status register records fault conditions that occur during drive operation. When any of these fault
conditions occur, the PWM output is automatically disabled. The user should monitor this register continuously for
fault conditions. A fault condition can be cleared by writing a “1” to the FaultClr bit in the FaultControl write
register group. (This does not automatically re-enable PWM output.)
