Other Parts Discussed in Thread: DRV8308,
For close loop control, DRV8308 EVM GUI, section 3.2 Quick Guide to Spin With Speed Control was followed. The following problem was found
- In the instruction On All Registers tab, I am not able to select the SPDMODE bits to 00 (FREQ) Mode. When I set it to FREQ mode it sets to PWM mode by itself.
- The speed control is not working. The RPM does not remain consistent upon giving load.
- The instruction provided in the last line of Section 3.1 was found untrue.
Please guide how can we operate the BLY171S-24-4000 (provided with EVM) in close loop control mode.
