Max Starting Current
FLOAT RW NV
Default: 0
Units: A
Admin Lock
USB Lock
Maximum Motor Starting Current Floating Point Format. This value can be
set (typically to 0) before starting the motor.
371
Max Starting Current
Scaled
UINT16 RW NV
Default: 0
Units: scaled A
Admin Lock
USB Lock
Max Motor Starting Current Scaled. Scaled by parameter “I Scale
Factor”. This value can be set to any value but is typically reset to 0.
372
Motor State (Current
Based)
UINT8 RO
Enum
Current based motor state. The motor state is determined by using the
current presently measured. This state indication runs independent of the
actual command being provided.
373
Speed RPM Scaled
UINT16 RO
Units: 0.1 RPM
The speed of the motor in scaled RPM (0.1RPM).
374
Torque Scaled
SINT16 RO
Units: 0.01 Nm
The motor torque in scaled Newton-meters (0.01Nm).
375
Efficiency Percent Scaled
UINT16 RO
Units: 0.01%
Motor Efficiency in scaled percentage (0.01%)
376
PTC Status
UINT8 RO
Enum
PTC Status as follows: 0 - No Fault, 1 - Over Temperature fault, 2 - PTC
Shorted fault, 3 - PTC Open fault
