4.5.5
Activation of safety function SS1 on a servo amplifier
The safe outputs can be configured in such a way that they can activate the safety function
SS1 (a and c) on a servo amplifier.
Activation of monitoring function:
}
The "Activate outputs" option must be activated in PAS4000. In this case, the monitor-
ing function affects the outputs on the module directly if a limit value is violated.
}
At least one monitoring function must be activated for the FS outputs. The monitoring
functions are activated by setting the O-data type "...DeactivateSS1M" to FALSE.
Activation:
}
A monitoring function violates a monitored limit value and sets the restart interlock to
"0".
or
}
The user program sets the O-data types (ST_O_DO and FS_O_DO) to "0".
4.5.5.1
Reaction on SS1-M (a)
}
The ST output O00 is shut down immediately.
}
The FS outputs are shut down,
–
if the speed drops below a configured standstill limit value for the automatic STO
or
–
after a configured delay time has elapsed (STO delay time). The delay time starts
running with a 1/0 pulse edge at the signal for the restart interlock or at the signal
for the FS-O data types.
}
If the delay time has elapsed and the signal for the restart interlock or FS-O data types
is "0", then the assigned output is set to "0".
}
If the delay time has elapsed and the signal for the restart interlock or FS-O data types
is "1", then the assigned output remains at "1".
}
If the delay time is running and another 1/0 pulse edge arrives at the signal for the re-
start interlock or FS-O data types, then the delay time is restarted.
