Help needed to get my 7i76E + 7i85S + 7i73 on my mill going.

It is fulfilled Gear E =1 + High Gear =32 ===total 33, this is how I read it.

Im sure there must be a typo hidden somewhere but I just seem to find it.

With above I can only run Gear E 0-100rpm, other gear settings/S commands nothing out to VFD.

S100 = runs at 135rpm
S50 66.5rpm
S10 12rpm

E + High gear 101 - 200rpm
S200 123rpm
S150 92rpm
S101 61rpm

There must be some errors in the comp code, but I cannot figure out what.

Made some changes but still not OK

I can get E and E+HG, D and A to run but with wrong rpm.
E S100 goes to overload and runs at 1.84Hz
S80 runs at 40.8Hz = 278 rpm

E+HG S200 goes to overload and 1.84Hz
S160 runs at 40.8Hz 221 rpm
S101 runs at 25.36Hz 137.2 rpm

D S350 1.74Hz
S280 runs at 40.8Hz 463 rpm
S201 runs at 28.9Hz 328 rpm

D+HG C and C+HG B and B+HG and A+HG are not working

setp hm2_7i76e.0.7i76.0.0.spinout-scalemax 2400
setp hm2_7i76e.0.7i76.0.0.spinout-maxlim 2500

MAX_OUTPUT = 2500.0 in INI

Max on each gearsetting the motor should run at 50Hz or there about and be adjusted down to each gears minimum from VFD.

I have just edited the comp with new ranges as per the enclosed picture = original gearbox speed and see what the actual result will be.

I´ll be back soon.

Here my findings

To get E in low gear to run as it should I had to edit setp hm2_7i76e.0.7i76.0.0.spinout-scalemax to 3255 (2400)

E S255 runs at 255.1 / 37.5Hz

E HighGear S325 runs at 202.9 / 37.4Hz !!! WTF !!!

D S430 runs at 425.5 / 37.4Hz

-
A S2000 runs at 1956 / 37.4Hz

.
All other gears nothing !

I found a bloody mess in hexadecimal numbers, will go down and test now.

faulty line int reqd_gear[12] = {0x0, 0x01, 0x21, 0x02, 0x04, 0x36, 0x08, 0x40, 0x16, 0x10, 0x48, 0x0};

Corrected int reqd_gear[12] = {0x0, 0x01, 0x21, 0x02, 0x22, 0x04, 0x24, 0x48, 0x28, 0x10, 0x30, 0x0};
