You have to observe the following points when carrying out the firmware
replacement:
• Do not switch off the 24 V control voltage while replacing the firmware.
• Firmware replacement always must be carried out completely, i.e.
firmware on optional safety technology module must be replaced, too.
• For firmware replacement we distinguish between release update and
version upgrade.
Note: When firmware is replaced in conjunction with the option
starting lockout ("L1"), this does not require any specific
measure, i.e. the additional measures described below only
apply to the use of option "S1"!
Firmware Release Update
When firmware in a drive controller is replaced by firmware of a new
release, this is called firmware release update (e.g. FWA-INDRV*-
MPH-04V06-D5 replaced by FWA-INDRV*-MPH-04V08-D5).
The described sequences of the firmware release update depend on the
configuration of the control section and the hardware (MMC or PC) used
for update. The basically recommended sequence of the firmware release
update is illustrated in the scheme below:
