Call examples
1. Position spindle:
//Positive acknowledgment resets Start:
U M112.0;
//InPos
R M 100.0;
//Start
//Negative acknowledgment, after error evaluation (state: MB114) reset with T12
start
U M113.0;
// Error
U I 6.4;
//Key T12
R M 100.0;
//Start
//Start with T13
U I 6.3;
//Key T13
AN F 112.0;
//Restart only when InPos or Error = 0
AN F 113.0;
S M 100..0;
CALL FC 18 (
Start := M100.0,
Stop := FALSE,
Funct := B#16#1, //Position spindle
Mode := B#16#2, //Shortest path
AxisNo := 5,
Pos := MD104,
FRate := MD108,
InPos := M112.0,
Error := M113.0,

2. Start spindle rotation:
CALL FC 18 (
Start := M100.0,
Stop := FALSE,
Funct := B#16#2, //Rotate spindle
Mode := B#16#5, //Rotational direction as for M4
AxisNo := 5,
Pos := 0.0,
FRate := MD108,
InPos := M112.0,
Error := M113.0,
State := MB114);
