I have resolver which is connected to feedback 1 of AKD servo device as position feedback of a motor and i should prepare a TTL-signal for  an external laser system (PIV: Particle image velocimetry). It is very critical to trigger the PIV exactly when the feedback position is for example at 10 grad. I am not sure if it is possible to use emulated feedback (x9) for this purpose or it is better to set digital output of x7 terminal as programmed limit switch to have a good accuracy.

thanks in advance for your help
