Technology cycles position spindle
Application
Interacting with the PLC program, the spindle which initiates a tool change should be:
• Traversed to an initial position,
• Positioned at a specific point at which the tool to be inserted is also located.
See chapter "Starting of command axes" and chapter "Control via PLC".
Coordination
The PLC and NCK are coordinated by means of the common data that are provided in SW
version 4 and later (see chapter "List of the system variables relevant for synchronized
actions")
• $A_DBB[0]: Take up basic position 1,
• $A_DBB[1]: Take up target position 1,
• $A_DBW[1]: value to be positioned +/- , PLC calculates the shortest route.
