Zero speed limit:
Enter in this field the maximum speed value above which the
output of the function block (ZERO) will be 0 (FALSE). If the
measured speed is less than the set value, the output (ZERO)
of the function block will be 1 (TRUE).
Frequency zero speed: It shows the maximum calculated
frequency values fM and fm (decreased by the hysteresis set).
If the displayed value is GREEN, the calculation of frequency
gave a positive result.
If the displayed value is RED, it is necessary to change the
parameters given in the following formulas.
1. Rotary axis, rotary sensor. The frequency obtained is:
rpm [rev/m in]

f [Hz]
60
2. Linear axis, rotary sensor. The frequency obtained is:
speed [m/min]

f [Hz]
60 * pitch [mm/rev]
3. Linear axis, linear sensor. The frequency obtained is:
speed [m m /s]

f [Hz]
Re solution
4. Hysteresis. To be changed only if: fM=green; fm=red
