5.10.2 Firmware update
Uncontrolled movements of the drive!
Risk of injury! All data in the control are overwritten and a software reset is
executed on the control.
▶ Switch the drive motor off! A software reset corresponds to a power-on
reset of the control and may only be carried out when the system is in a safe
condition.
Current firmware is made available by Rexroth together with the project files.
New firmware can be transmitted to the control under menu item "Service" →
"Firmware Administration".
Current firmware projects can also be downloaded from the Rexroth website in the
section "SYDFED" under "Download":

SWITCH-ON SEQUENCE OF ELECTRONICS/HYDRAULICS
Due to various monitoring routines implemented in the electronic assemblies, fault
messages may be generated in the case of an unfavorable order of switching on.
These error messages cause uncertainties, although they have no "real" cause of
fault.
In principle, it is valid that all SY(H)DFED control systems that are provided with
internal pilot oil supply automatically swivel to the operationally safe zero stroke
position in the event of a power failure. However, a precondition for zero stroke
is a minimum pressure between 8 and 12 bar, which the pump has to build up as
pilot pressure. This can always be ensured, when no oil can flow away from the
pump output (e.g. actuator line hydraulically blocked).
Observe the special case of suspended loads!
Activation sequence of digital electronics SYDFED
1. Voltage supply of the electronics
2. Set controller enable
3. Switch motor on
4. Suppress warnings until target speed has been reached
5. Open check valve (if provided)
1. Command value provision: αcomm = 5 % and p = 10 bar
2. Close check valve (if provided)
3. Suppress warnings
4. Switch el. motor off
5. Switch voltage supply of electronics off
