x and Z loadmeter

Hello


you can create a load meter for X and Z with pyVCP, indicating the motor overload?


thanks

If the drives have an analog output that indicates load, you can also monitor the voltage with 4 of the 7I77 inputs. Field inputs 0,1,2,3 are available as analog inputs in mode 1. These are protected (to up to 50V or so) but have fairly low resolution (8 bits and ~36V full scale)

i maybe wrong an would definitely not know how to do it, but could this not be done with some calculations based on the axis vol and commanded output.
ie low speed high effort (or high commanded output / high analogue output) = high load
high speed low effort (or low commanded output / low analogue output) = light load

maybe some of the pid value would give better a better window into he required info

OR maybe im just barking up the wrong tree altogether

for velocity mode drives, you could scale and subtract the actual velocity (encoder velocity) from the requested velocity (PID output) to get an idea of the load, but the difference is small in a well tuned velocity drive so the calculation is probably not very accurate.

For torque mode drives its easy, since the load is just the PID output (properly scaled)
