Standard T-Line-9 Paramacro Variables
Paramacro When a 1 is assigned to this value, the control:
1000 raises the transfer bar during a transfer cycle
1001 lowers the transfer bar during a transfer cycle
1002 advances the transfer bar or completes the drill cycle
1003 returns the transfer bar or retracts the tool
1004 stops the part program execution for any manual operations that need to be
performed on the station. If the PLC assigns a 0 to this variable, then the control
goes into automatic execution mode. A cycle advance/return or transfer bar/raise
lower request must be made by the PLC for the CNC to begin automatic axis motion.
1005 performs the cycle in metric units. If this bit is set to 0, then the cycle is performed in
English units.
Paramacro When the control assigns a 1 to this value, it indicates to PAL that:
1100 the transfer bar has been completely raised
1101 the transfer bar has been completely lowered
1102 the transfer bar is fully advanced or the drill cycle is at the cycle complete position
1103 the transfer bar is fully returned or the drill cycle is at the cycle retract position
1104 the tool is fully returned to the tool change position (as specified in the part program)
