5.8.2 Firmware update

Uncontrolled movements of the drive!
Risk of injury! The system overwrites all of the data on the control and software
resets it!
▶ Switch the drive motor off! A software reset is the same as switching the control
off and back on again and you must only carry it out with the system in a safe
state.
Rexroth provides the current firmware with project files in each case. You need
firmware FWA-HYDRV-HDB....20V12 or higher.
You transfer new firmware to the control in menu item "Downloads" -> "Firmware
Management".
Current firmware projects are also available to download on the Rexroth website
under "Download", visit: http://www.boschrexroth.de/sydfe -> sydfed
The HS5E is delivered ex-works with the current firmware. You can find older
firmware by visiting: http://www.boschrexroth.de/sydfe -> sydfed, or on
request.

5.9 Switch-on sequence of electronics/hydraulics

Due to the different monitoring routines that are integrated on the electronics
assemblies, the system can issue fault messages in the case of adverse switch-on
sequences. These fault messages lead to uncertainty even though there is no "real"
reason for them.
Be aware of the special considerations with suspended loads!
