Reference [%]
Variable
name: SNVT
type:
Value:
nviRefPcnt SNVT_lev_percent Min. Max. Resolution:
-163.840 % +163.830 % 0.005 %
This variable sends the speed reference to the frequency converter. It represents a percentage of the reference range of the frequency converter.
In closed loop operation the reference is interpreted as the setpoint.
Reference [Hz]
Variable
name: SNVT
type:
Value:
nviRefHz SNVT_freq_hz Min.: Max.: Resulution:
0.0 Hz 6,553.5 Hz 0.1 Hz
This variable sends the speed reference to the frequency converter in Hz, in open loop mode.
In closed loop mode it is used as the Set-point.
Closed Loop Set-point 1-3
Variable
name: SNVT
type:
Value:
nviSetpoint1-3 SNVT_lev_percent Min.: Max.: Resulution:
-163.840 % 163.830 % 0.005 %
This variable sends up to 3 different set-points to the frequency converter via the bus.
NB!
Please refer to section Reference Handling for more information
Bus Feedback 1-3
Variable
name: SNVT
type:
Value:
nviFeedback1-3 SNVT_lev_percent Min.: Max.: Resulution:
-163.840 % 163.830 % 0.005 %
This variable sends up to 3 different feedback signals to the frequency converter via the bus.
NB!
