NETWORK VARIABLES
6.5.4 Set frequency (0.1Hz increments) (network input SNVT_freq_hz
nviInvSetFreq)
The set frequency can be set in 0.1Hz increments.
⋅ Data acceptance timing........... At network variable receive (nv_update_occurs event)
6.5.5 Set frequency (0.005% increments) (network input SNVT_lev_percent
nviInvSetFreqP)
You can monitor the output frequency of the inverter in 0.005% increments on the assumption that the
frequency set in "% set reference frequency (nciInvSetFreqBas)" (Refer to page 85) is 100%.
⋅ Data acceptance timing........... At network variable receive (nv_update_occurs event)
For example, when "% set reference frequency (nciInvSetFreqBas)" = 60.0Hz and "set frequency
(nviInvSetFreqP)" = 50.000%, set frequency = 60 × 0.5 = 30Hz
Data Name Initial Value Range Increments
nviInvSetFreq H7FFF 0.0Hz to 400.0Hz, H7FFF 0.1Hz/bit
REMARKS
• When H7FFF is set, the set frequency is as set in "start/stop/simple speed setting (nviDrvSpeedStpt)" (Refer to
page 48)
.
• H7FFF is not reflected as the actual set frequency value.
• Always set frequency (Hz) regardless of the Pr. 37 setting.
Data Name Initial Value Range Increments
nviInvSetFreqP 100.000% 0.000% to 163.830% 0.005%/bit
REMARKS
• Control can not be exercised at less than the minimum frequency resolution (0.01Hz) of the inverter.
