Tool/software: Code Composer Studio
Greetings! I`m using your DRV8711 to drive MENA17(1.7A) motors. Now I want to use it for NEMA 23(4A). So I`ve connected IRF530 mosfets and 0.055ohms current sense resistors(I`ve tried multiple values here).My settings on the driver are :
CTRL register-> 0x0C11(800ns dead tim, 1/4 step, internal stall)
OFF register -> 0x00C8
TBLANK register -> 0x0000//I`ve tried 0x00FF max blank no effect
DECAY register -> 0x0180 // slow decay
DRIVE register ->0x05F4
So in this case I can`t set the current level above 2.5A. I`m receiving short circuit error! My power supply is 12V. I can increase it to 24 if it`s needed.
Any ideas?
Thanks!
