Control Unit: key diagnostic parameters (details in List Manual)
Parameter
Name
Description
r0002
Control Unit status display
Status display for the Control Unit
r0018 Control Unit firmware version
Displays the firmware version of the Control Unit. For the display parameters for the firmware version of the
other connected components, see the parameter description in the List Manual.
r00037
Control Unit temperature
Displays the measured temperature on the Control Unit.
r0721
CU digital inputs, terminal actual value
Displays the actual value at the digital input terminals on the CU. This parameter shows the actual value,
uninfluenced by simulation mode of the digital inputs.
r0722
CO/BO: CU digital inputs, status
Displays the status of the digital inputs on the CU. This parameter shows the status of the digital inputs un-
der the influence of simulation mode of the digital inputs.
r0747
CU, digital outputs status
Display of the CU digital output status. This parameter shows the status of the digital inputs under the influ-
ence of simulation mode of the digital inputs.
r2054
PROFIBUS status
Displays the status of the Profibus interface.
r8937
PN diagnostics
Display to diagnose the cyclic PROFINET connections.
r9976[0..7]
System utilization
Displays the system load.
The individual values (computation load and cyclic load) are measured over short time slices; from these
values, the maximum, the minimum and the average value are generated and displayed in the appropriate
indices. Further, the degree of memory utilization of the data and program memory is displayed.

Parameter
Name
Description
r0002 Drive operating display
The value provides information about the current operating status and the conditions necessary to reach the
next status.
r0020
Speed setpoint smoothed
Displays the actual smoothed speed/velocity setpoint at the input of the speed/velocity controller or V/f char-
acteristic (after the interpolator).
r0021
CO: Actual speed value smoothed
Displays the smoothed actual value of the motor speed/velocity.
r0024
CO: Output frequency, smoothed
Displays the smoothed converter frequency.
r0026
CO: DC link voltage smoothed
