G30 Reference Positions

[stevo1]

I have a Fanuc 15MF. Is the G30 2,3,4, reference positions an option?

When I try to program a G30P(2,3,4) it givea an alarm improper G-code.

My floating reference position of 30.1 does work.

I have the machine set up in the 1st reference position, center of table and face X0Y0Z0. However because of the G30 command not working I have to have hard numbered positions in the programs for Tool touch off, Pallet change, and Tool change. What I don't like about this is if the 1st reference position has to be changed or tweeked it effects all of the numbers for these positions.

Correct me if I am wrong but when the 1st reference position has to be changed or tweeked it will not effect the positioning of the 2,3,4 reference because they work form zero return position.

Usually G30 is standard option, the way to use it is for example:

G30 Z0;

This line will take the Z axis to the 2nd. reference position, you have to have the parameter of the 2nd. reference poit position to a a value so the commanded motion take the axis where you want. This parameter number depends on what control model you have.

Setting these parameters to values does not help the "Improper G-Code" Alarm. I have always used these positions when setting up machines when the ATC, or Tool Touch off is different then home position. I have the parameters set to values and still get the alarm. I tried G30, G30P2, G30P3, G30P4, all with an axis specified in the blocks.

I have never had to have this activated. As you stated I thought this was a standard function but I have found data to support that this is an option but I am not 100%. For other various controls I see option settings identifiy 2nd, 3rd, 4th reference positions which leads me to believe that this is an option.

I have it working properly now without the improper G-code alarm.

FYI it is a option in the control.

Thanks for all the help,

I wasn't aware of that, this is new to me in this control. Thank you for the information.
