Issue Details

I am using a PCI motion controller card with a open-loop stepper motor. If I send a 0 velocity command to the controller, the motor will still move 1 step every 10-16 seconds. 

Solution

Setting the load velocity to 0 counts/s or 0 revs/s is not a valid parameter. Use the Stop Motion command instead of overriding the velocity to stop the motor. 

Additional Information

For more information about your motion controller's performance, please look at the Specifications section in your motion controller's user manual.
