RCK_EnhancedFeedAxis (FB)

FUNCTION_BLOCK RCK_EnhancedFeedAxis

This function block is implemented to build an enhanced feed axis for rotary cutter system; the built enhanced feed axis can have up to 5 position measure channels from encoder or other measure devices that can provide position value in real time. The selected channel can be dynamically switched between the configured position measure channels when the rotary cutter system is running. This function block also handles the position value latched by registration sensor and converts to proper unit for the registration function block.

Note

• This function block must be called in the POU which is executing in the MotionSolution_Task.

Note

• This function block must be called before RCK_RotaryCutter for better system performance.
