Switching the system on/off

Warning
!
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.
Case a) is not permitted when Safety Integrated is used. The automatic
upgrade/downgrade must never be disabled when Safety Integrated is used.
(automatic firmware update (p7826) must be equal to 1)
Case 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 (see Chapter 9.5 "Acceptance
test").
Before personnel may re--enter the hazardous area, the drives should be tested to
ensure that they exhibit stable control behavior by briefly moving them in both the
plus and minus directions (+/–).
This is especially important specifically for high--speed linear or torque motors.
What has to be observed when switching on?
The safety--related functions are only available and can only 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.
