Axis going in one direction

479 views  November 7, 2021

Here are some thoughts on troubleshooting this:

  •  If an axis goes only in one direction, then that is because the driver is not seeing the direction signal for that axis.
  • The installer or configuration file that you used at the beginning should have configured everything, but you can verify the configuration using the documentation for the product.
  • Try tracing the pin with the signal that is not getting there. Do you see action in the DIR LED for the axis on the board, in the Diagnostics? You can also measure it on the terminals of the driver for the axis with the issue. The reading should change from 0to +5vdc and back and forth.
  • If another axis is working ok, you can swap with the axis that is working ok connections, components, configurations, etc...
