The reaction times refer exclusively to the inputs and outputs on a servo
amplifier with safety card when:
The signal at the inputs changes

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 account.
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

signal in the safety 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.
Internal processing times of the safety card

– T : Scan time of the safety card's processor system
CYCLE
– T : Processing time for the safety card's shutdown path
OUT
T : Processing time for the safe pulse disabler in the servo am-
