I am doing a revamp of a machine with motion control.
I have no data of the inertia of the load on a certain motor, but I should want to know it for my engineering.
In the old drives I can capture analog output that indicates the setpoint speed, and an analog output for the current. I am not sure if I can set it at the torque generating current or if it is only possible to read the total current.
I should be able to scale the two signals so I have signals in rpm and ampere.
I also know the reduction ratios of the gearbox.
What could now be a procedure to get a value for the inertia of the load?
The old motor is a servomotor.
