Measuring inductance of motor with HDC2450

Hi,

I want to measure inductance of motor with HDC2450.

Current of motor increases linearly. Despite, I set Max Speed at 100, Acceleration and Deceleration at 50000



Current is yellow.

Normally, this current should increase exponentially.

You can set your linearity to become an exponential factor in your configurations tab.

Under "Commands", "Command Adjustments", and "Linearity 1" or "Linearity 2", select the type you wish to use.

Thanks, I find it . But I don't know the difference between "exp weak" and "exp med" or "exp weak" and "exp strong".

With "exp strong", current of motor descreases and with "exp weak", it increases !

Take a look at page 68 of the user manual. It is explained there.
