CHAPTER 7 - APPLICATIONS AND PROGRAMMING

Stopping (P124
0 and P125=1):
1) In most applications only the constant toque control can be used for
pump stopping, 1 point=constant;
2) This method is used for water columns that are not very high;
3) Set P126 initially to the same value of P121, provided it is correct;
4) Set P126 in such a way that at the end of the pump stopping process
the motor is not still enabled;
5) As soon as the pump is disabled, a gradual pressure drop should be
noted without significant pressure oscillation, mainly at the end of the
stop, when the retaining valve is closed.

– Hydraulic pump stopping with constant torque, 1 point
Stopping (P124
0 and P125=2):
1) Linear deceleration torque, 2 points=linear;
2) Applied to high water columns;
3) At first you can set P126 for 10% to 15% lower than the value of P121,
provided this value is correct;
4) Set P127 so that when the beginning of the stopping process, the pressure
decreases gradually and no sudden pressure oscillation occurs;
5) Set P126 so that at the end of the pump stopping process the motor is
not still enabled.
