Activation of safety function STO on a servo amplifier
The module provides all the necessary functions to implement the safety function STO on a
servo amplifier.
Features:
}
The FS outputs O01 and O02 are used to activate the safety function STO on a servo
amplifier.
}
The configurable STO delay time must be deactivated in PAS4000 by entering a value of
0 ms.
}
The "Display monitoring result at the outputs" option must be activated in PAS4000. In
this case, the result of the monitoring functions 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.

Integrated protection mechanisms
When the PSSu E F PS1(-T) or PSSu E F PS2(-T)(-R) is used to supply the system, the
module supply is buffered for 20 ms if the supply voltage is interrupted.
The module provides the following diagnostic data:
}
Start-up error
}
Configuration error
}
FS communication error
}
Bus termination error
}
Temperature error: too warm
}
Sensor error
}
Output error
The module has the following protection mechanisms:
}
Common second shutdown route, tested regularly
}
Cyclical output tests
