Centroid CNC control sales, service, training and support
On CNC11 systems, running in velocity mode or in position ("precision") mode, the Centroid control software has no information about the amount of current and torque the servo drives are using to achieve the requested moves.
If you would like to see how much torque a drive is actually using (e.g. to verify servo sizing, or to check the effectiveness of the counterbalance on a vertical axis) you can monitor torque using the digital keypad on the Yaskawa drive.
The Sigma V drives provide monitoring displays of many internal values. Monitoring displays are numbered "Unxxx". Instantaneous current/torque output, as a percentage of continuous rated output, is Un002.
If Un002 changes too rapidly to get a useful reading, you can use Un009 instead. Un009 is the accumulated load over a 10-second period, again in percent of continuous rated torque.
