Switching the system on/off

Warning
!
From SINAMICS SW2.5 onwards, the following applies:
In a system configuration, the firmware versions of the DRIVE–CLiQ components
can only differ from the versions on the CF card, if either
a) the automatic upgrade/downgrade (parameter p7826) is deactivated, or
b) components with a new firmware version can no longer be downgraded to the
status of the version available on the CF card.
Scenario a) is not permitted when Safety Integrated is used. The automatic
upgrade/downgrade must not be disabled when Safety Integrated is used.
(automatic firmware update (p7826) must be equal to 1)
Scenario b) is only permissible if this combination has been explicitly approved by
the manufacturer.
Warning
!
After hardware and/or software components have been changed or replaced, it is
only permissible to boot the system and activate the drives when the protective
devices are closed. Personnel shall not be present within the danger zone.
Depending on the change made or what has been replaced, it may be necessary
to carry out a partial or complete acceptance test (refer to Chapter 9.5,
"Acceptance test").
Before allowing anybody to re–enter the danger zone, you should test that the
closed–loop control behaves in a stable fashion by briefly moving the drives
forwards and backwards (+/–).
It is especially important to carefully observe this for high–speed linear or torque
motors.
What has to be observed when powering–up?
The safety–related functions are only available and can be activated after the
system has completely booted.
We recommend that the "safe operating stop (SBH)" function is selected.
For axes with SE/SN, the stop position is used to internally check the position
when powering–up.
