4. Parameter description
Parameter
●
If the pressure command is set not by the analog input, but from the keyboard panel,when
P.225=99999,and P.170=1, the target pressure set by the current between 4 and 5 terminal, the
feedback pressure set by the voltage between 2 and 5 terminal. When P.225=99999,and P.170=2,
the target pressure set by the voltage between 2 and 5 terminal, the feedback pressure set by the
current between 4 and 5 terminal.

The diagram to the fixed mode for the plus pump control operation is below:
In operation, if the state which the pressure instructions (or frequency instructions) than feedback
pressure of great value to continue, PID output (equal to output frequency) will increase, and has
been reached maximum frequency (P.215). The state shall continue to the time which P.209
specified, if the instructions and feedback value deviation than P.217 setting value, will add pump
control.
