3.5 Data Recording

3.5.1 How to Use the Data Recorder

The E-517 includes a real-time data recorder. It is able to record several

input and output signals (e.g. current position, control voltage) from different

data sources (e.g. axes or output channels). The gathered data is stored

(temporarily) in "data recorder tables"—each table contains the signal from

one data source. You can configure the data recorder flexibly, e.g. select

the type of data and the data source. The E-517 provides 3 data recorder

tables (can be read with TNR?) with 8192 points per table.

Start Recording

Data recording is triggered automatically with four commands:

■ STE (step response measurement),

■ IMP (impulse response measurement),

■ WGO (wave generator start) and

■ WGR (restarts recording when the wave generator is running).

Recording always takes place for all data recorder tables and ends when

the data recorder tables are completely filled.

Read Data

The last recorded data can be read with the DRR? command. The data is

reported in GCS array format. For details regarding GCS array see the

separate manual (SM146E), which is provided on the E-517 CD. Reading

out recorded data can take some time, depending on the number of points

to be read! It is possible to read the data while recording is still in progress.

Configure Recording

For general information regarding the data recording you can send HDR?,

which lists available record options, and gives information about additional

parameters and commands concerned with data recording.

The data recorder configuration, i.e. the assignment of data sources and

record options to the recorder tables, can be changed with DRC, and the

current configuration can be read with DRC?. Upon delivery, the data

recorder is preset to record the current positions of the axes.
