Rexroth IndraDrive Rexroth IndraMotion MLD Application Examples
Starting from the basic parameters, you have to make some fundamental set‐
tings for the application example "process control for vibration damping".
The number and functions of the analog inputs differ according to the type and
configuration of control section.
For more detailed information on the different control sections, see the hard‐
ware documentation for the control sections "Rexroth IndraDrive - Control
Sections for Drive Controllers" (Project Planning Manual). For the example de‐
scribed below, we use a control section of the CSH01.1C type. See the Project
Planning Manual of this control section for the pin and connector assignment.

The amplified sensor signal is connected to the corresponding connection. The
input voltage range of the control sections is +/-10 V. The amplification of the
measuring amplifier is selected such that the biggest possible window of the
input voltage range is used. Due to the vibration properties of the mechanical
system in this example, we have selected a sensor with the following charac‐
teristic values:
Sensitivity 10 mV/g
Evaluation range up to 50g
The resulting amplification factor is fa = 20 and the amplified voltage signal of
the sensor is +/-10 V.
