Split from mm430 stuck at minimum frequency.

Hello,

there is 0-100% written in network comment, so the result should be percentage of nominal current.

Actual current is sent from drive as word, where 0..4000h corresponds to 0..100% of nominal current. 4000h is 16384d, so to get percentage of nominal current, you have to divide actual current communicated value by 16384 and multiply by 100. Or simply dividing by 164 (after rounding 163,84 to integer).

With regards

Martin
