- After the download is complete, the “Download Successful” message will appear inside the HyperTerminal window.
At this point the system is still in download mode. Now, close the HyperTerminal program and disconnect your laptop
from the drive and cycle the control power to drive control boards.
- After the boards are powered up, you need to transfer the parameters from the Terminal memory back to drive.
Refer to “Reloading the Parameters” described below.
Reloading the Parameters
IT IS IMPORTANT TO REFER TO THE PRODUCT SAFTEY ADVISORY BEFORE UPGRADING FIRMWARE. IT IS ALSO
IMPORTANT TO REVIEW ALL FIRMWARE RELEASE NOTES FOR CRITICAL CHANGES.
Once power is reapplied, the drive may come up with all the parameters from NVRAM. But if you have upgraded the Firmware
from revision level 2.002 (or earlier), the NVRAM will be cleared. All other information such as operating hours, external fault
messages, specific drive name, trending setup, etc. are also cleared. If you have upgraded the Firmware from revision level
3.001 or later, the data in the NVRAM will still be intact.
For major revision level upgrades, the majority of the parameters that were stored in the Operator Interface or other external
means can still be used, but there may be things such as new parameters, changed scaling on an existing parameter, or
added functionality to existing parameters that may have to be addressed.
To reload the parameters from the Operator Interface, once again obtain ADVANCED level access. Then follow the same
steps to get to the [F2] (UTILITIES) -> [F7] (TRANSFER) -> [F4] (PARAMETERS). Then choose [F3] (MEM>DRV). This will
prompt you for confirmation, and you can press [F8] (YES).
The parameters will then be transferred. There are differences between parameters for different major revision levels, so you
may get some error messages, and a Transfer Incomplete message. THIS IS NORMAL.
You can also transfer from the Card to the Drive using [F2] (CRD>DRV), and the difference is that you will first get a screen
asking you to choose from all the available parameter listings on the card. Select the one you want using the arrow keys, and
press [Enter]. Then you can press [F8] (YES) and transfer the parameters. Once the parameters are transferred, press the
[F10] (EXIT) key to get back to the main screen.
It is important to go through the parameters and ensure the settings are proper for the VFD. New parameters may need to be
changed for the specific VFD application, and this should be understood from reviewing the release notes beforehand.
Security Parameters:
Verify that the parameters P709 “Port Logic Mask” and P711 “Write Mask Cfg” are both set to 7FH (i.e. first 7 bits are set to 1).
Smallest CapkVAR:
It is essential for the new features introduced in 6.002 or higher, that the Parameter #795 Smallest CapkVAR
introduced in the 6.xxx Database is programmed properly. This parameter defines the smallest capacitor installed at the
Line Filter Capacitor bank in the VFD.
For example if the drive has 3 line capacitors at 500, 500 and 400kvar then set this parameter to
400. Failure to do so may result in equipment damage or render the VFD temporarily inoperable.
