sc12, 720 deg/s sc13, 1720 sc14, 0.1

${SCRIPTEXEC} ${ecmccomp_DIR}applyComponent.cmd "COMP=Motor-Generic-2Phase-Stepper,  MACROS='I_MAX_MA=1000,I_STDBY_MA=200,I_CTRL_GAIN=1.0,I_CTRL_INT=0.26'"

sc18, 720 deg/s sc19, 1720 sc20, 0.1 sc21, 2000deg/s sc22, 2200deg/s (higher velo than this vibration starts) sc23, 3000deg/s works but much vibrations..probably loosing steps

EL7047

${SCRIPTEXEC} ${ecmccomp_DIR}applyComponent.cmd "COMP=Motor-Generic-2Phase-Stepper, MACROS='I_MAX_MA=1000, I_STDBY_MA=200, U_NOM_MV=48000,R_COIL_MOHM=8000,L_COIL_UH=9700 ,SPEED_RANGE=2'"

sc24, 720 deg/s sc25, 1720 sc26, 0.1 sc27 2000, works nice, current looks a bit strange sc28 2200, works nice, current looks a bit strange sc29, 3000 OSC alot, loses steps
