converted back to Hertz (Hz) is reflected in DRV-18 Base Freq.
The following formula converts an RPM value into Hertz (Hz). In this formula, the number of motor poles is set at M2-
10 Pole Num. The motor pole number must be configured correctly to ensure proper operation.

Note
When a change is made to the ‘nciNmlSpeed’ variable, it is automatically reflected in the ‘nciNmlFreq’ value. For
example, if the current ‘nciNmlSpeed’ value is set to 1800 RPM, the ‘nciNmlFreq’ is set to 60.0 Hz, DRV-18 Base
Frequency is set to 60 Hz, and BAS-11 Pole Number is set to 4 (poles), decreasing the ‘nciNmlFreq’ value to 1700 RPM
changes the ’nciNmlFreq’ value to 56.7 Hz (a rounded-up value of the DRV-18 Base Frequency value), and DRV-18
Base Frequency to 56.66 Hz.
When the values set at ‘nciNmlSpeed’ or ‘nciNmlFreq’ are changed, the changes are reflected in DRV-19 Start
Frequency and Drv-20 Max Frequency as well. In the example above, if the ‘nciMaxSpeed’ is set to 100.000% and
‘nciMinSpeed’ is set to 10.000%, DRV-19 Start Frequency is changed to 5.66 Hz and Drv-20 Max Frequency is changed
to 56.66 Hz.

Description
The ‘nciNmlFreq’ is used to configure the motor’s base frequency. The ‘nciNmlFreq’ value is essential in configuring
the motor’s minimum and maximum frequency (‘nciMinSpeed’ and ’nciMaxSpeed’) because these values are
expressed as a percentage of the value set at ’nciNmlFreq.’ The default ‘nciNmlFreq’ value is 60 Hz which is the
default frequency set at DRV-18 Base Freq.
