The trigger output can be used as a response to the trigger input. An edge at the trigger input can thus generate a pulse at the trigger output. This function can be used in the “Current control trigger pulse” mode. In order to generate a reproducible behavior at the trigger and/or LED output via a signal at the trigger input, the signal at the trigger input should have a steep edge.

If the LED output and the trigger output are to be used, any trigger mode can be selected, except for the “Standard output” mode. If only the trigger output is to be used in response to the trigger input, only the trigger modes “Synchron”, “Synchron inverted”, “Synchron pulse with separate trigger delay” and “Synchron pulse inverted with separate trigger delay” can be used. With “Synchron” or “Synchron inverted” the pulse length and the delay of the pulse with respect to the trigger input are specified via the PDOs. In the trigger modes “Synchron pulse with separate trigger delay” and “Synchron pulse inverted with separate trigger delay”, the values for the pulse length and the delay of the pulse are specified at the trigger output.

The delay times can be specified via the CoE interface or in the PDOs. The delay times are then added together.

Possible from FW03 The function for using the trigger output in response to the trigger input described in this chapter can only be used from FW03 onwards.

When using an external trigger, it should be noted that, based on internal terminal delays, the minimum delay between the trigger input and the signal output is approximately 2 µs. The offset of 2 µs must also be observed for all set delay values (regardless of whether they are set via PDO or CoE). The resulting delay is always

If the trigger output is used in response to the trigger input, it should be ensured that the signal at the trigger output has a jitter of <±1 µs.
