Hi dear supporters
We are using DRV10970 motor driver IC and its EVM board. But we are facing with a problem about direction changing feature. On the other hand we are using Faulhaber 2214 BLDC motor in our setup. When we are reversing direction by FR pin motor current consumption increase three time compared to other direction. Not only consumption changes but also speed of motor is different from other direction. For Same duty cycle, in reversed direction scenario motor rpm decrease dramatically.
For example
DS 50 % 3030 3060
DS 80 % 4865 5320
DS 100 % 6020 6850
