Maximum Value

+255 deg

This is the actual Bus Voltage as read by
the software from an analog input port.
Units are in volts.

Inverter temperature determined by NTC
device on heatsink power structure.
Can be configured to generate either a
warning or fault when heatsink reaches 80
degrees C.

Filtered Velocity Feedback
[Filt Vel Fdbk]

Parameter Number

269

Parameter Type

Maximum Value

+8 x Base Speed

This parameter contains a filtered version
of velocity feedback. The value contained
in this parameter is not meant to be used
for control, only for display and monitoring
purposes.

4096 = 100% flux

Factory Default

100%

Minimum Value

12.5%

Maximum Value

100%

This parameter displays the level of motor
field flux calculated by the current proces-
sor and limited by the Min Flux Level
parameter (Param 174).

Calculated Torque
[Calc Torque]

This parameter will display the calculated
value of motor torque as determined by the
Velocity Processor. The actual value of
motor torque will be within 5% of this value.
Scaling is 4096 at rated motor torque. This
data is updated on a 2 millisecond basis.
