The settings marked red in the table above from the high current range (above 2A RMS motor current) should
not be used as they will violate specification of the module!

In addition to the settings in the table the motor current may be switched off completely (free-wheeling) using axis
parameter 204 (see TMCM-1141 firmware manual).
