376		-In the parameter setting of group F9, 20mA is the maximum value of the transducer with a range of 16bar, and F9.01/F9.29/F9.31 are the setting parameters for the water pressure in the VB in percentage. For example when the inverter is required to keep the pressure at 8bar, modify F9.29=50%. F9.01 is the upper limit of water pressure setting, it needs to be greater than or equal to F9.29, it is recommended to set F9.29=F9.01
