Limit Switches Do Not Work Correctly With NI-Motion Hardware Hardware: Motion Control>>Power Drives
Problem: After configuring my National Instruments motion controller card and my National Instruments Drive, my limit switches do not work correctly. The home switch on Axis 1 does not ever change state, and all of the limits on Axis 2 do not seem to work at all. Solution: Check to ensure that you have the correct cable for your motion control system. This behavior arises when you use a SHC68-C68-A (Analog Cable) in place of a SHC68-C68-S Motion Cable (Part #186380). Both of the cables will connect to the motion controller card and the drive; however, the analog cable has common ground pins which prevent the system from working correctly. Please refer to the link below for the pricing information on the motion control cable. Related Links: Products and Services: Shielded Cables Attachments:
