7.11.4.2Volumetricflowratelimit
The minimum and maximum volumetric flow rate can be limited to suit the system
requirements using the volumetric flow rate limit. Once the parametrized volumetric
flow rate limits are reached, the pump speed is limited by the motor speed controller.
A selection can be made between P 2850[8] - QMax and P 2847[3] - QRef as the
source of the limit value by making a source selection (QMaxSrc). P 2847[3] - QRef
can be used to specify the limit via the volumetric flow rate value, which, for example,
can be set variably using an analogue input.

7 Control
For the purpose of volumetric flow rate limitation during the process or in individual
motion blocks, a scaling factor (P 2872 HYD_Tab_Limit) can be used in some
control modes (see Table) to influence the preset limitation. ( see also section
"Hydraulic motion block table" on page195
