Example for calling subroutine 52
3.26 Subroutine 53 - Turret3_CODE_T (tool change control for turret with
coding function)
Purpose
Subroutine 53 is used to control the turret with coded tool positions and function of adjacent
tool change. The difference between the subroutine 52 and the subroutine 53 is that the
subroutine 52 uses binary tool position codes while the subroutine 53 uses tool position
codes made according to a specific common turret.
During a tool change, the NC interface signal "Feedhold" (DB3200.DBX6.0) is set; this
means that the part program can only continue to run only after the tool change.
The turret positioning is prohibited in the case of an Emergency Stop, turret motor overload
or program test/simulation.
