CoolStep is disabled by default, and it isn't clear how to disable this feature after it is turned on. App Note 02 mentions setting SEMIN to 0, but the TMCM-1110 does not have a 0 setting for SEMIN. So how can this feature be disabled?
To disable CoolStep on the TMCM-1110 StepRocker, write a value of 0 to Axis parameters 170 and 172.
