7.1.2.7.1 Object 0x2147: Hybrid flow
This parameter holds the flow of the hybrid pump (constant pump). The unit is relative to the nominal flow of
the servo pump.
Example:
The servo pump has a nominal flow of 140 l/min. This corresponds to a set signal of 16384. The constant
pump has a flow of 80 l/min. On the scale of the servo pump this corresponds to:

7.1.3 Pressure demand value generator

The pressure demand value generator comprises the following functions:
• Limit - limits the demand signal
Chapter "7.1.3.3 Limit function", page 68
• Scale - multiplies the set signal by a definable slope
Chapter "7.1.3.4 Scaling", page 69
• Ramp - limits the rate at which the input signal changes
Chapter "7.1.3.5 Ramp", page 70
The following figure shows the inner structure of the pressure demand value generator with the implemented
functions.
Detailed description of the signal flow of the demand signal and the parameters influencing this behavior:
Chapter "6.2 Command value path", page 39
Forwarding the demand value to the controller
The pressure demand value (0x6390) is forwarded to the pressure controller in the control modes 3, 4 and 5.
