MICROMASTER 4 (MM4): Reading a parameter set from an AOP

  • Entry
  • Associated product(s)
This FAQ applies to MICROMASTER 4 (MM4) Advanced Operator Pannel (AOP)

How can I read a parameter set from an AOP?

Proceed as follows to upload a parameter set from an AOP:

1.

  • Before you can upload a parameter set from an AOP this must first be saved in the AOP
  • If required, first upload the parameter sets from the drive inverter (function UPREAD) into the AOP. For information on this, refer to the Operating Instructions of the AOP (Advanced Operator Panel) in Chapter 2.3, Page 7 "Downloading parameter sets".
  • Note:
    Please note that level 4 parameters can only be saved in an AOP parameter UPREAD if the drive inverter is in the service mode (P0003 =4) during the UPREAD. This is especially important when using the SVC at the MM440.

2.

  • Using the PC connecting kit connect the AOP to your PC/PG and open the commissioning tool DriveMonitor or STARTER.

3.

  • Check the internal parameter settings of the AOP.
    Information on this is provided in the Operating Instructions of the AOP, in Chapter 2.5, Page 10 "Setting AOP parameters“
  • Further, proceed as follows:
    • Select "Internal" as mode (refer to Chapter 5, Page 21);
    • Select "Parameter" (refer to Chapter 6, Page 23);
    • Select the AOP parameter set;
    • Select all parameters (Option "All");
    • Set P0003 to 3.
  • The following internal parameters of the AOP must be checked and if required, set:
    • P8552    Basis slave address = 0    (the address can be selected as required)
    • P8553    standard baud rate > 6     (e.g. 8 = 38400 baud)
    • P8554    autobaud = 0                    (autobaud off)
  • These settings should permit communication between the AOP and DriveMonitor/STARTER.

4.

  • Set the AOP into the slave mode: "AOP is a slave of the PC" on the AOP display.
    The steps for DriveMonitor and STARTER will now be described separately.

DriveMonitor
(Information on Page 10 Chapter 2.6 of the AOP operating Instructions)

5.1

  • Open DriveMonitor and set-up a new project. Make the following settings in the field "Drive properties":
    •  Select the drive unit type (MM420, MM440 etc.);
    • Select the drive unit version;
    • Bus address = AOP basis slave address (P8552) + parameter set number;
    • Number PZD = 2 (another setting in the AOP Manual).
  • Note:
    The bus address is the sum of the AOP basis slave address (P8552) and the number of the parameter set with which you wish to establish the online connection.
    Bus address = parameter set number, if P8552, basis slave address = 0.

6.1

  • Check/set the ONLINE settings under "Options > ONLINE settings…". Select "USS" as interface, the COM port used and the same baud rate that you set at the AOP (P8553).
  • Note
    The changed communication settings will become effective the next time that DriveMonitor starts. This is the reason that you should close DriveMonitor and re-open it if you have made changes.

7.1

  • Establish an online connection. The message "a device unit was not able to be identified" is displayed – this is normal, therefore click on OK.
  • Note:
    For AOP FW1.59 or higher, the device is identified and a message is not output.

8.1

  • Certain parameters have the entry "PNU unknown" in the parameter value field. This is normal. The parameters involved are either display parameters (starting with "r") or other parameters that are set so that they initiate a process and then reset themselves (e.g. P0040 - resetting the energy consumption meter). Further, certain PROFIBUS and USS parameters, P0918, P0927, P2010, P2011, P2012 and P2013 are not saved. This is because a change to these values when downloading would cause the process to be interrupted. These parameters are not saved in AOP and when required, can be manually set at the drive inverter.
  • Note:
    For AOP FW1.59 or higher, all parameters are transferred with the exception of r0947 – r0949, P0952, r2024 – r2031, r2110 and P2111.

 

STARTER
Communication with STARTER only functions with an AOP from FW1.59 or higher

5.2

  • Open STARTER, set-up a new project and insert a new single drive unit. Make the following settings in the field "Insert – SINAMICS":
    • Select the drive unit type (MM420, MM440 etc.);
    • Select the drive unit version;
    • Address type = PROFIBUS/USS/PPI;
    • Bus address = AOP basis slave address (P8552) + parameter set number.
  • Note:
    The bus address is the sum of the AOP basis slave address (P8552) and the number of the parameter set with which you wish to establish the online connection.
    Bus address = parameter set number, if P8552, basis slave address = 0.

6.2

  • Check/set ONLINE settings under "Options > Set PG/PC interface…“ Select "PC COM port (USS)“ as interface under "Properties…“ the COM port used and the same baud rate that you set
    at the AOP (P8553).

7.2

  • The values of parameters r0947 – r0949, P0952, r2024 – r2031, r2110 and P2111 are also not displayed in STARTER. Instead of the values, three question marks "???" are displayed.
