more information. Afterwards, the speed adaptation is activated by "DRn vari‐
able speed enable" (X4 by default or ASF control word F0.20 from communi‐
cation). X1, X3, X4 do not have a specific order to be set. They can be set all
at once or in any order.

System configuration
F1.05 Command value: Pressure
This parameter makes the command value of DR/DRG pressure control
available to the drive so that pressure drops can be identified and the boost
function can be activated (cf.
chapter "Boost Function" on page 76
).
F4.29 Pump type
The pump used is selected via this parameter according to the following ta‐
ble. Setting the pump type to "0" requires to parameterize the pump data
manually in F4.30 and F4.50 to F4.54.
If the pump type is set to manual (F4.29 = 0), the values set in F4.30, F4.50,
F4.51, F4.52 must be checked, so the values are not in conflict with some pa‐
rameters (for example F3.19 Speed adaptation: Minimum speed and F3.20
Speed adaptation: Maximum speed) in the DRn functions, see
for reference. The user gets APE1/APF1
fault depending which value is not set correctly. In the error case D0.86 and
D0.87 (Warnings) and D0.88 and D0.89 (Errors) must be evaluated, to find
which value has to be changed. For more information, see chapter
14.3 "Warning Code" on page 124
