Setting Method for Pr.10.12
Default: 0
Settings
0: Use the existed setting (default), judging by the feedback deviation
1: Set the low water pressure percentage (%), check for any fault by the
feedback physical quantity
 When the pressure sensor is set to 10 kg, set Pr.10.49 = 0 and Pr.10.12 = 10.0% (that is,
deviation=1 kg), and if the set point = 3 kg and feedback < 2 kg, then the AC motor drive follows
the setting for Pr.10.20.
 When the pressure sensor is set to 10 kg, set Pr.10.49 = 1 and Pr.10.12 = 10.0% (that is,
deviation=1 kg), and if the set point = 3 kg and feedback < 1 kg, then the AC motor drive follows
the setting for Pr.10.20.
