Configuration of Pressure Sensor
For application using Rexroth HM20 pressure transducer, configuration pa‐
rameters of HM20 sensor can be automatically loaded by selecting the corre‐
sponding type code in parameter F2.10. Please make sure the right analog
input channel has been set through [F2.00]...[F2.02] before setting [F2.10],
since the configuration parameters (AI input mode and scaling factors) will be
set for the selected channel for pressure feedback.
The pressure feedback is required to observe the hydraulic load and to trig‐
ger the automatic boost function. Therefore, analog input AI2 has to be con‐
figured with respect to the installed pressure transducer.
