Can anyone tell me how to call a sub program on these controllers and also does anyone know what the G29 torque limit command and g22 torque skip command are and how they are used? I have a sample program for transfering a part from one spindle to the other and I don't under stand these codes:
IE:
.
.
.

G29 PW=30
G22 W0 D5 L2 F250 PW=20
.
.
.
.
PLEASE HELP.

how to call a sub program
as usual CALL O101
what the G29 torque limit command and g22 torque skip command are and how they are used
1. part transfer from one spindle to another
2. tapping, drilling

G29 is a "Torque Limiter" command and will tell the control not to ever push the W axis above 50% load if PW=50 is programmed. Great for protecting the machine when transferring in case a workpiece doesn't eject. G28 will turn it back off. Be sure to use these commands on a line by themselves.

The G22 line is a "Torque Skip" command. This will feed the W axis until a load is reached and then will stop feeding the axis. Typically steps will be needed in your jaws in order to have a stop that this can push against.

G22 W-.5 D.15 L.1 F50 PW=35 will pus onto the part -.5" will slow down .15 from contact point and will feed up to .1 past contact point at 50 IPM feedrate. When load =35% it will stop feeding and continue to next block.

Any questions, let me know. This is standard on all 2 spindle machines.
