Hi,

The speed acceleration scale factor "MAX_ACCEL_KRPMPS_SF" is defined in main.h.

Thanks,

Jiaxin

Hello, what exactly does MAX-ACCEL_KRPMPS-SF mean?Only one macro
There is also an acceleration setting function, The maximum acceleration (value between 0 and 1). What does 0~1 mean and how should the maximum value be taken

Hi Qicheng,

"MAX_ACCEL_KRPMPS_SF" should be the scale factor to make "gMotorVars.MaxAccel_krpmps" become a value between 0~1. However, it seems the resultant variable "ctrlHandle->traj_spd.maxDelta" is not used anywhere. Can you monitor the value in ccs debug window?

Thanks,

Jiaxin
