2.7 Speed stop at minimum pressure values
If pressure actual value (ZP177.119–) is smaller than P actual value minimum
(ZP177.145–) and pressure set value (ZP177.120–) is smaller than P set value minimum
(ZP177.144–) speed limitations are set to 0. As a result in this low pressure area neither
volume nor pressure controller are active.
The speed limitation is suspended, if the pressure set value is greater than P Set value
minimum.
Figure 13: Speed stop at minimum pressure values
„P set value minimum“ and „P actual value minimum“ set pressure values stop the drive
if actual values are falling below this threshold value
This function prevents the drive from drifting slowly during the pressure control procedure
in the event of small set and actual pressure values.
The limit does not take effect until both (AND) limits have been underrun.
By setting the default values typical values were already entered.
The function is only activated in the pressure control system.
