The Denominator defines the increments in user unit for one motor revolution.
The Numerator defines the increments in motor unit for one motor revolution. This value must be set at 4096.
Motor_position = Numerator / Denominator * User_position
Example:
1 motor revolution corresponds to a displacement of 5 mm on the load.
The desired user resolution is in µm.
Setting parameters:
Numerator = 4096
Denominator = 5000
User unit = µm
