eTrigger is an innovative system that allows the continuous monitoring of the encoder state and produce a trigger output at the exact encoder positions. Up to 4 separate encoder positions may be used for triggering purposes.
It's a perfect solution for an automatic control of industrial and commercial machine vision applications. High speed communication is the key for a flexibility and efficiency. The ability of “on the fly” injections, gives the opportunity to reach the optimal performance and save your time for trigger configuration.
The build-in processor is used to calculate not only the status of the encoder, but also the trigger point in advance*, depending on velocity of the motor. The Hardware supports up to 1000 KHz Encoder Frequency.
Typical Applications:
- Time efficient industrial and commercial applications
- Vision solutions / camera trigger
- Motion control applications
Features:
- Up to 4 Programmable triggers
- 4 maskable output channels for each trigger
- Selectable movement direction (forwards, backwards or both) for each trigger
- Ability to store the configuration into Flash ROM
- Support for high-speed encoders with operating frequency up to 1000KHz
- Realtime trigger position calculation depending on current motor speed
- Ethernet/UDP and RS232 communication interfaces
- Configurable trigger duration
