LonWorks Network Variables

nciNmlSpeed

Definition 

Network config input SNVT_rpm nciNmlSpeed

Explanation 

This configuration property is used to provide the nominal speed of the motor.

Valid Range 

1 to 65000 RPM

 

The value 0xFFFF represents invalid data.

Default Value  1800 RPM

nciNmlFreq

Definition 

Network config input SNVT_freq_hz nciNmlFreq

Explanation 

This configuration property is used to provide the nominal frequency of the motor.

Valid Range 

0.0 - 650.00 Hz

Default Value  60.00 Hz

nciMinSpeed

Definition 

Network config input SNVT_lev_percent nciMinSpeed

Explanation 

This configuration property is used to define the minimum speed of a motor. Its 
value is entered as a percentage of nominal speed, as defined by the Nominal 
Speed (nciNmlSpeed) configuration value. The value of the minimum speed must 
be validated against the value of the maximum speed as follows:

 

-163.840% <= minimum speed <= maximum speed <= 163.835%

Valid Range 

-163.840% to 0.000 % or 0.000% to +163.835%

 

The value 0x7FFF represents invalid data.

Default Value  0.830%

nciMaxSpeed

Definition 

Network config input SNVT_lev_percent nciMaxSpeed

Explanation 

This configuration property is used to define the maximum speed of a motor. Its 
value is entered as a percent of nominal speed, as defined by the Nominal Speed 
(nciNmlSpeed)  configuration  value.  The  value  of  the  maximum  speed  must  be 
validated against the value of the minimum speed as follows:

 

-163.840% <= minimum speed <= maximum speed <= 163.835%

Valid Range 

-163.840% to 0.000 % or 0.000% to +163.835%

 

The value 0x7FFF represents invalid data.

Default Value  100.000%
