The question of "Accel" in motorware

Other Parts Discussed in Thread: MOTORWARE

hi:

In motorware , there is "#define USER_MAX_ACCEL_Hzps                 (20.0)      // 20.0 Default"   in user.h 

then  in user.c  there is " pUserParams->maxAccel_Hzps = USER_MAX_ACCEL_Hzps"  

but other place  in proj_labxx.c  there is " CTRL_setMaxAccel_pu(ctrlHandle,_IQmpy(MAX_ACCEL_KRPMPS_SF,gMotorVars.MaxAccel_krpmps));"       this " gMotorVars.MaxAccel_krpmps"  != USER_MAX_ACCEL_Hzps .  

what differents is about these two parameters ?   

thanks

best regards!
