Part Number: DRV8701
I am considering using the DRV8701 for driving a linear motor. I would appreciate any comments or recommendations for setting the current regulation components/parameters (Data sheet 7.3.3, Current Regulation) as I am experiencing high inrush currents with the motor during bench testing. The normal operating current with no load on the motor is less than 1A. However I am recording inrush current spikes as high as 39A which last for 20µsec or so. The high current spikes occur when the motor is at the end of it's travel (either extended or retracted) and power is re-applied to try to drive the motor in the already bottomed out direction. It sounds like if a fault were to occur that it would reset automatically based on the information of 220.127.116.11, OCP but I would appreciate confirmation of this. Thank you in advance for your assistance.
