The AOP30 Advanced Operator Panel is an optional input/output device for SINAMICS DC MASTER converters. It can be separately ordered. The operator panel is only designed for installation outside the converter (e.g. in a cabinet door up to 4 mm thick), installation cut-out 141.5 Г— 197.5 mm.

It sets itself apart as a result of the following properties:

• Graphics-capable LCD display (240 Г— 64 pixels) with backlighting for plain-text display and a bar-type display for process variables
• LEDs for displaying the operating states
  
  • RUN green
  • ALARM yellow
  • FAULT red
• Help function describing the causes of faults and alarms and how to resolve them
• Time and date memory with internal battery backup
• 26-key membrane keyboard
  
  • Keypad for operational control of a drive
  • Local/remote switchover for selecting the operator control location (operator panel or customer terminal strip/communications channel has the control authority)
  • Numeric keypad for entering setpoints or parameter values
  • Function keys for prompted navigation in the menu
• RS232 and RS485 interface
• Connection for a 24 V power supply
• The converter can be controlled using the AOP30 up to distances of 200 m. A cable with integrated 24 V power supply can be ordered in standard lengths as an accessory.
• Two-stage safety strategy to protect against accidental or unauthorized changes to settings.
  
  • Operation of the drive from the operator panel can be disabled using the control inhibit function so that only parameter values and process variables can be displayed on the operating panel.
  • A password can be used to prevent converter parameters being changed by unauthorized personnel.
• Front panel with degree of protection IP55, IP20 at rear

The AOP30 communicates with the SINAMICS DC MASTER drive via the serial RS485 interface.

The AOP30 can communicate with the Standard CUD as well as with the Advanced CUD of the SINAMICS DC MASTER.

A 24 V power supply is required to operate the AOP30. For a maximum cable length of 50 m, this can be taken from the CUD of the SINAMICS DC MASTER. An external power supply must be used for cable lengths greater than 50 m.

Assignment of the RS485 cable with a 24 V power supply from the CUD – max. cable length 50 m

Assignment of the RS485 cable when using two CUDs (24 V power supply from one CUD) – max. cable length 50 m

Assignment of the RS485 cable when supplying the AOP30 from an external 24 V DC source – max. cable length 200 m

Assignment of the RS232 cable for connecting to an AC SINAMICS unit (not for SINAMICS DC MASTER!)
