Table 17: Description
Gray area
 Missing input Voltage detection threshold
Speed [RPM]
 Actual Speed related to analog 0-10V input Voltage value (see par. 5.4, table 13 contacts 7 and
8)
Max
 P26 (Max RPM set)
Min
 P27 (Min RPM set)
Setpoint
 Example of Actual Speed related to a specific Vset Voltage value
Sby
 Input Voltage at which the motor goes in Stand by
Vin [V]
 Input Voltage value to control the pump in ACT mode
Different thresholds are managed by the pump, from Non-detection to Max speed.)
For further information about ACT control mode and parameters adjustment, see par. 7.5.3.
