Read Trajectory Data Function and 7344 card

[whatsthis4]

The Read Trajectory funtion in Flexmotion is apparently able to buffer position data up to 333Hz (3ms sample time).

Is this motion card dependent?

I read somewhere on the forum that for the 7344 MOTION CONTROLLER, reading position is only possible up to a rate of 100 Hz (10ms sample time)?

Can anyone clarify this or alternatively explain to me how High Speed Capture could possibly be relevant to all this?

Thanks

Chris,

The difference is the hardware 3ms is a 7350 and 7344 is the 10 ms. The diference is which card you by.
