STEVAL SPIN3201 Motor very close to starting advice on parameters so close
Dear community I have purchased a STEVAL STM3201 spin kit,
After getting the data sheet for my motor the motor is nearly spinning it is so close.
Eventually I will use halls but to walk before I can run I will try sensor-less first
I have used the motor control workbench 5.4.3 to generate the code from a template using the en.STSW-SPin3201. Im using atollic true studio code compiles without errors
I take a project and a default motor template SDK5x - STEVAL-SPIN3201 - BullRunning.stmcx then I change all the parameters to suit the motor I am using to do this i follow UM2152 manual line by line.
The motor nearly starts It connects to the motor work bench
I kept getting error FOC Duration every time
So I changed the parameter pwm frequency from 13,000 to 5,000 line
#define PWM_FREQUENCY 5000// 13000
in the file drive_paramaters.h
recompiled major improvement
the FOC Duration error now disapeers
I set the speed voltage with pot and press run the motor attempts and starts spinning several times then stops saying speed feedback error on the motor workbench GUI
I look through all the paramaters and one looks suspiscous
paramater 0x5C ramp duration is set to 0mS I can not find the paramter for ramp duration in any of the header files
Where is the ramp paramater
Also changed the PI KP and KI gains down to try and start it
the motor paramaters are all entered correctly
out of all these files shown in the picture which one contains the ramp speed parameter I think because par mater reg 0x5C is set to zero so theres no ramp time and it dosent start
heres the file list
please can anyone suggest which paramater i need to change the motor spins several times over a half second then stops im so close any help wouldbe much appriciated.
