The Emergency Stop function must bring the machine to a standstill in accordance with
stop category 0 or 1 (STO or SS1).
The machine must not restart automatically after EMERGENCY STOP.
When individual safety functions (Extended Functions) are deactivated, an automatic
restart is permitted under certain circumstances depending on the risk analysis (except
when Emergency Stop is reset). An automatic start is permitted when a protective door is
closed, for example.
After hardware and/or software components have been modified or replaced, all protective
equipment must be closed prior to system startup and drive activation. Personnel shall not
be present within the danger zone.
It may be necessary to carry out a partial or complete acceptance test or a simplified
functional test (see chapter "Acceptance test") after having made certain changes or
replacements.
Before allowing anybody to re-enter the danger zone, you should test steady control
response by briefly moving the drives in forward and reverse direction (+/–).
To observe during power on:
The Safety Integrated functions are only available and can only be selected after the
system has completely powered up.
