● The diagnostic code is stored in parameter S-0-0390
● The diagnostic text is stored in parameter S-0-0095 It is available in German
Error memory
All warning messages are stored in a diagnostic memory, and all error mes-
sages are stored in an error memory. The messages are each provided with a
time stamp.
Field data acquisition
The functional extension of (F)ield (D)ata (A)cquisition (FDA) allows process
data of a servo-hydraulic actuator in the field to be recorded. The acquired data
describe the load of the axis components in the field and simplify diagnostics
and fault detection if servicing or repairs have to be carried out. The data are
stored on the local storage medium of the control system.
Further information on field data acquisition can be found in ⮫ Chapter 9.4
"Field data acquisition (FDA)" on page 59.

Operational states
Fig. 16: Operating states
The servo-hydraulic actuator provides an operating state control, which is
largely based on the device control and state machine of the IndraDrive firm-
ware. The operating states of the actuator are shown in the following in a
strongly simplified form.
