Function description
}
The limit value is exceeded
}
Internal errors are present
To determine the overall reaction times, the corresponding internal processing times in the
servo amplifier, bus systems, periphery devices and controllers must also be taken into ac-
count.
Processing time of the digital input
The response and error reaction time takes into account the following processing times:
}
Processing time of digital input T
card to be detected once a signal has changed at the input. The processing time takes
into account the input filter time, temperature drift, spread of components, etc.

Error reaction time:
}
The time it takes for the shutdown signal to be provided for the servo amplifier's power
element, once a limit value has been exceeded or an internal error has occurred.
