How can I monitor the voltage output sent to each servo axis programmatically?

Hi I am wondering if it is possible to monitor the voltage that's being sent to a servo motor during an axis position movement (in particular quantities such as max voltage). I am using a PID controller to drive this servo motor.

Thanks

Hi Vlad,

Unfortunately, I don't think there is a way to programmatically read the voltage output to the drive, as the voltage is all determined internally by the controller circuitry on the board. Depending on the controller though, you may be able to physically route the output terminal to a spare analog input channel and read in the voltage that way. This example Analog Input with 73xx Motion Card shows you how to program LabVIEW to do this.
