I have automatic tool chance on NC lathe PITTLER with 12 tool positions.

Every tool has it's own contact , TWS aushoben NO contact and motor CW and CCW rotate.

I need some reference for M6 Txx tool change procedure in classic ladder.

Step by step :

1. M6 Txx tool change is requested
2. Check curently tool loaded ; if not start tool change procedure
3. send pulse for TWS aushoben
4. If contact NO ON rotate tool turet CW or CCW
5. When tool requested in position stop rotate motor , send impuls to TWS abgesetz
6. if NC ON , tool change procedure finished.

see page at :

and the cl-ladder turret example .

is this a servo motor or just a dc motor ?
have you a picture of the toolchanger it will help if we need to make adjustment for any other movement or
input etc , such as grey encoder for position .
