PCI-6259 and SCB-68 control two step motor

[ForrestGan]

Hi,

    I am using the PCI-6259 to provide pulse train through SCB-68 to CMK connection to control two step motors.

    one step motors pulse train is from "ctr 0 out", and the second step motor's pulse train is from "ctr 1 out".

    these two step motors supposed to work independently, but somehow, when controlling one step motor to move back and forth for a few times, then you can see that the second step motor move a few degrees. (since I have a stop switch installed, so I can count the steps when step motor moves to initial position. )

    Does anyone have similar "cross talk" problem?

Thank you very much!

Hi,

   Thanks for the suggestion.

   But when I try to apply digital filter, it shows errors:

   is it because the DAQ doesn't support? I tried on both PCI-6259 and NI PCI-MIO-16XE-10, both show the same error. 

DaqError: Digital filtering is not available for the given terminal.
