6.3 PLC user program for turning (UPGMTURN)
General
The PLC user program UPGMTURN is conceived for a turning machine with a switched
three–phase spindle motor, 2 stepper motor axes and a toolholder with 4 to 6 tools. To adapt
the program to the particular machine, it can be parameterized via PLC machine data.
The SINUMERIK 802S comes with this PLC user program (UPGMTURN) already integrated
in the flash memory of the control system.
The PLC 802 Programming Tool is used for PLC programming. This programming tool inclu-
des the PLC program UPGMTURN as an example project (Note: The version of the UPGM-
TURN that comes with the tool must not necessarily be the same as the version that comes
with the control system!).
The user can thus use this PLC project as a basis for his own PLC project.
6.3.1 Function
The PLC user program (UPGMTURN) processes all necessary signals from and to the NC
and the machine control panel (MCP) and monitors the EMERGENCY STOP function.
UPGMTURN handles axis and spindle signals, controls the toolholder, coolant and lubricant
supply.
Processing operator signals
