FIRMWARE STRUCTURE

5.1

GENERAL

The drive control firmware is to be found in FLASH U20 of the control board; its software version (Dx.xx)
is displayed by the Status page, whereas the user's parameters may be saved on EEPROM U11 in the
same board. Both components are located beneath the metal support of the keypad. EEPROM U11 is
assembled on a 4+4 pin socket to be easily removed when required.
The software version installed may also be read on the two seven-segment displays installed on the
control board by pressing the PRO key on the board located beneath the two displays. For instance, digit
52 stands for software version D5.02.
The parameter storage on EEPROM U11 may be checked - when the machine is not running - by
pressing the CPU RESET key for a while (said key is to be found on the control board beside the PRO
key) which is equivalent to temporarily switching off the control board.
WARNING
The user may interact with the parameters contained in the "M", "P", "C", "A" and "W" menus.
Mxxx parameters are read-only parameters; the user cannot interact with them.
Parameter P000 is the key-parameter containing the access P/Ns allowing to modify any other Pxxx and
Cxxx parameters. Cxxx parameters, unlike Pxxx parameters, may be changed only when the ENABLE
digital input is not active. All said parameters allow the system to be completely configured; some of them
are changed during the auto tuning stages.
Also Axxx parameters are read-only parameters; they are displayed when an alarm trip is stored. The last
two digits related to the alarm tripped will blink and will be displayed on the two 7-segment displays
assembled on the control board.
Also Wxxx parameters are read-only parameters. They contain some warning messages that do not imply
the drive lock - unlike the alarm messages above. The last two digits of the alarm tripped will remain fixed
and will be displayed on the two 7-segment displays assembled on the control board.
Never press the CPU RESET key if the machine is running.
