Siemens Sinamics AOP30 Operator Panel: Beyond the User Manual

The AOP30 is an operator panel with graphical display/membrane keyboard and has a part number of 6SL3055-0AA00-4CA5. The device can be installed in a cabinet door which is between 2 mm and 4 mm thick. It is an input/output device for converters of the SINAMICS series, preferably for cabinet installation. The AOP30 includes the following features:

  • Graphical backlit LCD display for plain text display and a bar display of process variables
  • LEDs for display of the operating states
  • Help function describing causes of and remedies for faults and alarms
  • Keypad for operational control of a drive
  • Local/remote switchover for selecting the operating location
  • Numeric keypad for input of setpoint or parameter values
  • Function keys for guided navigation in the menu
  • Two-stage safety concept to protect against accidental or unauthorized changes to settings
  • Front panel with degree of protection IP55


The current operating states, setpoints and actual values, parameters, indices, faults and alarms are displayed on the display panel. Desired language must be downloaded to the AOP30 prior to commissioning. If just one CU320‑2 Control Unit controls several power units (multi-motor drives) in the SINAMICS S120 drive system, the parameters, alarms and faults of all the connected devices can be simultaneously displayed and processed on the AOP30 Advanced Operator Panel.

The AOP30 Operator Panel can be used for the following activities:

    • Parameterization
    • Monitoring status variables
    • Controlling the drive
  • Diagnosing faults and alarms
