Question:
Are there any further steps to be taken in GDC after
'Secure transfer to controller' to save the parameters in the controller (9300, ECS, ...)?
Answer:
With the
'Secure transfer to controller' command, all GDC parameter sets are transferred to the controller (up to 5!, depending on the controller and its software version). Afterwards, the parameter sets will be read back from the target system and compared with the original data. In this way, you can check whether the parameter sets were properly transmitted. The following parameter sets are considered:
- Parameter window in GDC -> current parameter set in controller (RAM, i. e. volatile user memory!)
- PSet-1 in GDC -> parameter set 1 in fail-safe memory (e. g. EEPROM) in controller
- PSet-2 ... PSet-4 in GDC -> parameter sets 2 ... 4 in fail-safe memory in controller (only for 9300 Servo, 9300 Vector, 9300 Register)
Data transfer sequencer 'Safe writing to controller':
1. Go to the menu item
Drive parameters and select
Secure transfer to controller.
2. Depending on whether the rotor displacement angle and the communication parameters shall be transferred or not, select
Exchange unit or
Duplicate.
3. In the window that appears you can see the codes which will not be transferred. Click
OK to start the parameter set transfer.
4. After this, the parameter data will be checked and compared again. For this, the parameter sets will be read again from the controller. A window will appear in which you will be asked whether the display codes are to be considered. In general, this dialog can be closed with
No.
5. When the parameter data is completely identical, a message window or a dialog will appear in which all controller codes differing from the transferred parameter set will be displayed. Differences may be due to different software versions or different device features of the transferred parameter set and the device available. The code comparison can be saved or printed out. If you do not want to save or print the dialog, click
OK to exit the dialog.
Important!
If you only use the current parameter window in GDC (e.g. if only
one parameter set is used; typical characteristic: the user uses the function keys F5 to F7 for data verification between PC and controller),
after execution of the 'Secure transfer to controller' command, the transmitted parameter set additionally has to be saved via code C0003 in the EEPROM of the controller.
If this is not done and the supply voltage is switched off, the default GDC setting will be loaded after mains switching and the required function will no longer be given in the controller.
Please note:
After execution of 'Secure transfer to controller', the active parameter set should always be permanently saved in the EEPROM of the controller through the parameter selection (1...4) in code C0003.
