Hello all
Anyone know what DRV10983 registers can be dynamically updated while the motor is running?
We have a direct drive pump whose motor is fairly difficult to drive, we are getting fairly good results with the DRV10983 but it needs to be better, the motor's torque isn't constant over 360 degrees, the motor's loading changes depending on what gas or solvent is being pumped, the motor characteristics change with temperature and there are significant differences between individual motors - the motor is far from ideal but we are stuck with it.
I think our problems may be overcome by dynamically tuning the DRV10983 while the motor is running - some registers seem to dynamically change things and some don't - is there a list of what registers can change and take immediate effect? When exactly do other updated registers take effect?
