Part Number:DRV10983-Q1
I have a DRV10983EVM which I have successfully used to drive my motor. I have produced a dedicated board using the DRV10983-Q1 and I am struggling to tune the motor with the same parameters. I have tried several different ranges of the key parameters to no avail. I then went through the tuning procedure with the EVM and Q1 in parallel and all seemed well until I went to the closed loop control on page 16-19.
When in closed loop mode the motor current increases it then starts to slow down as can be seen below
wMotConfig1 = $034B
wMotConfig2 = $1A3A or 1A5A
wMotConfig3 = $0060
wMotConfig4 = $358E
wMotConfig5 = $BB6F or 3B0F
wMotConfig6 = $3132 or 3172
wMotConfig7 = $0569
I have tried various CL accelerate values with no success.
Why would the parameters change between the EVM and Q1? ... and can you point me in the right direction with which parameter to change
Thanks in advance
