C-863.12 Mercury Controller MS249E Version: 1.2.1 75
The settings for configuring the data recorder can only be changed in the volatile memory of
the C-863.12. After the C-863.12 has been switched on or rebooted, factory settings will be
active unless a configuration is done with a startup macro.
Reading general information from the data recorder
➢ Send the HDR? command (p. 157).
The options available for recording and triggering are displayed together with the
information on additional parameters and commands for data recording.
Configuring data to be recorded
You can assign the data sources and record options to the data recorder tables.
➢ Send the DRC? command (p. 147) to read out the current configuration. Data recorder
tables with the record option 0 are deactivated, i.e., nothing is recorded. By default, the
data recorder tables of the C-863.12 record the following:
− Data recorder table 1: Record option 1: Commanded position of the axis
− Data recorder table 2: Record option 2: Current position of the axis
− Data recorder table 3: Record option 3: Position error of the axis
− Data recorder table 4: Record option 73: Control value of the axis
➢ Configure the data recorder with the DRC command (p. 145).
Configuring the recording trigger
You can specify how the recording is to be triggered.
➢ Get the current trigger option with DRT? (p. 150)
➢ Change the trigger option with the DRT command (p. 149). The trigger option applies
to all data recorder tables whose record option is not set to 0.
Setting the record table rate
➢ Send the RTR? command (p. 185) to read out the record table rate of the data
recorder.
The parameter indicates the number of servo cycles required for recording each data
point. The default value is 10 servo cycles. The servo cycle time of the C-863.12 is 50 µs.
➢ Change the record table rate with the RTR command (p. 185).
As the record table rate increases, the maximum duration of the data recording is
increased.
