The drives normal frequency resolution is 0.1Hz.
Selecting these two parameters as a reference automatically selects high resolution control (unless a frequency limit is hit or slip compensation is
enabled). The frequency in this case will have a resolution of 0.001Hz. Pr 1.18 defines the reference (either positive or negative) with a resolution of
0.1Hz. Pr 1.19 defines the fine part of the reference (always positive). The final reference is given by Pr 1.18 + Pr 1.19. Therefore Pr 1.19 increases
positive references away from zero, and decreases negative references towards zero.
0: Precision reference update disable off
1: Precision reference update disable on
When this parameter is set to 0, the pre-ramp reference (Pr 1.01) is updated with the precision reference parameters (Pr 1.18 and Pr 1.19). If the
precision reference parameters are changed while this parameter is set to 0, the pre-ramp reference will be updated immediately.
When this parameter is set at 1, the precision reference update parameters (Pr 1.18 and Pr 1.19) are continually read and updated in internal memory
but the pre-ramp reference (Pr 1.01) is not updated. Because the precision reference has to be set in two parameters, this parameter being set to a 1
prevents the reference from being updated while the parameters are being changed. This prevents the possibility of data skew.
