Setting the Speed Display Scale (P.028)

Parameter P.028 (Speed Display Scaling) defines the scaling value applied to the
manual reference, the selected speed reference, and the output speed displays.

P.028 must be set to 100 for nvoDriveSpeed to show the correct percent of nominal
speed. This value is written by the LonWorks board at start up.

Refer to the VTAC 7 User’s Guide for more information about P.028.

Setting the Network Output Register Sources (P.066
to P.069)

Parameters P.066 through P.069 define the signals written to network output registers
1 through 4. These parameters read/write over the network. Set these parameters as
follows:

P.066 = 0 (Motor Kw display value)

P.067 = 7 (Outer control loop error)

P.068 = 8 (Outer control loop output)

P.069 is not used.

Parameter Range:

10 to 9999

Default Setting:

Synchronous speed based on H.001 (assuming a
4-pole motor)

Parameter Type:

Tunable
