NETWORK VARIABLES
6.8.20 Reference frequency setting (network input config SNVT_freq_hz nciNmlFreq)
Set the frequency used as the reference of "speed adjustment (nviDrvSpeedScale)" (Refer to page 49),
"speed monitor (nvoDrvSpeed)" (Refer to page 50), "maximum speed (nciMaxSpeed)" (Refer to page 99) and
"minimum speed (nciMinSpeed)" (Refer to page 99).
* 60Hz for the Japanese and NA version and 50Hz for the EC and CH version.
⋅ Data acceptance timing........... At network variable receive (nv_update_occurs event)
6.8.21 Speed adjustment default value (network input config
SNVT_lev_percent nciDrvSpeedScale)
You can set the default value of "speed adjustment (nviDrvSpeedScale)" (Refer to page 49).
⋅ Data acceptance timing........... At network variable receive (nv_update_occurs event)

REMARKS
• Refer to page 85 for details of Pr. 390.
• To make the change of "reference frequency setting (nciNmlFreq)" be reflected to the operation speed, a value is need to
be written to "speed adjustment (nviDrvSpeedScale)".

REMARKS
• Write and read the setting value from the network. You can not read and write from the inverter.
• The value stored in the inverter is rounded up. For example, 1.005% is rounded up to 1.010%.
