Motor Control TMC260 Technical Inquiry

Motor Control TMC260 Technical Inquiry [Copy link]

 

The newly designed motor driver module uses the TMC260 chip, which can drive the motor normally. However, no matter whether the motor is stalled or not, it will output a stall alarm signal. Is there any great god who can help me? The driver configuration is as follows: send262(0x00000ul); send262(0x90135ul) ; send262(0xa0000ul); send262(0xD7a0ful); send262(0xEF040ul); I bought a demo version with money. The same configuration can be used normally on the demo version, but the circuit board I designed will always stall and alarm. I compared the hardware of the two and found that they are almost the same, with the same working frequency.

There may be a problem with the reading speed. Check the manual to see if the circuit configuration is correct. The hardware is almost the same. See if the difference has any effect. Measure the signal.

The external frequency of the two is the same. This signal is automatically output by the chip and should have nothing to do with the speed I read.

This signal is automatically output by the chip. Check if there is a corresponding input signal. Is the measurement normal?
