I am currently using a motordrive, PN: DRV10983 to drive a brushless DC motor made my Maxon, PN:368852. I am having a lot of difficulty getting the motor to rotate at all and it instead appears to just chirp or make small jumps. The three motor parameter registers are configured as such: 0x20 = 0xEA, 0x21 = 0x9B, 0x22 = 0x2A. I am attempting to use I2C for full control (ie speed/breaking) and so have MSB of 0x01 set to 1.
So far I have smoked 2 of these chips when I was under the impression they had protection to avoid this - which in and of itself causes me to believe something is wrong. The motor is within the spec for the drive in terms of current, resistance, and speed constant.
