LonWorks Network Variables

NviDrvSpdScl

Definition

Network input SNVT_lev_percent nviDrvSpeedScale

Explanation

This input network variable provides scaling for nviDrvSpeedStpt (0.005%
resolution).

For example, if the value of nviDrvSpeedStpt is 100% and nviDrvSpdScl value
is 150%, then the actual speed setpoint value is 150% meaning that the drive
should run at 1.5 times nominal speed in the forward direction. A negative value
for nviDrvSpdScl sets the drive direction to reverse.

For example if nviDrvSpeedStpt value is 100% and nviDrvSpdScl value is -150%,
then actual speed setpoint value is -150%, meaning that he drive should run at
1.5 times nominal speed in the reverse direction.

Valid Range

-163.840% to 0.00 % or 0.00% to +163.835%

The value 0x7FFF represents invalid data.

Default Value Defined by nciDrvSpdScl.
