6.16.27 Torsion compensation
With MP_compTorsionFact you can perform a torsion compensation
between the position and speed measuring systems.
The torsion compensation regulates the difference in position that results
from the elasticity between the motor (rotary encoder) and the position
measuring system. An additional torsion motion is added to the speed
controller.
Enter a specific drive elasticity factor in MP_compTorsionFact. The block
diagram shows how the torsion compensation works.
• 1: Torsion compensation
• 2: Position controller
• 3: Speed controller
• 4: Current controller – power module
•5: Motor
• 6: Elastic coupling
•7: Machine
• 8: Linear encoder
This function is only available when using the CC 61xx, UEC 11x or CC 424
controller unit!
