Table 14: Examples of calculation
Example of calculation of the
adjustment start point for P40 = ISP (4-
20 mA analog signal)
Example of calculation of the
adjustment start point for P40 = VSP
(0-10 Vdc analog signal)
36
MAX point (10Vdc - 2mA) = maximum analog signal value
Motor minimum speed (Parameter P27)
Motor maximum speed (Parameter P26)
Adjustment zone
Minimum speed operation zone (Parameter P27)

Standby zone
 P27 = 900
 P26 = 3600
 Calculation of the adjustment start point value =
(maximum value - zero point) x (P27/P26) + zero point =
(20-4) x (900/3600) + 4 = 8 mA
 P27 = 900
 P26 = 3600
 Calculation of the adjustment start point value =
(maximum value - zero point) x (P27/P26) + zero point =
(10-0) x (900/3600) + 0 = 2.5 V
