3.5 Commands
The module specific commands are explained in more detail on the following pages. They are listed
according to their command number.
3.5.1 ROR (rotate right)
With this command the motor will be instructed to rotate with a specified velocity in right direction
(increasing the position counter).
Internal function: First, velocity mode is selected. Then, the velocity value is transferred to axis parameter
#0 (target velocity).
The module is based on the TMC429 stepper motor controller and the TMC262 power driver. This makes
possible choosing a velocity between 0 and 2047.
