Why would you want to be homing when running a program in Auto mode, your machine should be homed when you first start up your machine, (REF ALL HOME) G28.1 is not needed.

How have you written the code you want to use??

That was a good question.
its turning machine with C axis (A). the spindle work in position mode then speed mode and again in position mode. so we need to go home in rotary axis.

So how are you using the G28.1 it needs to know what axis you want to move.

Try it with G91G28.1A0. axis move information,

or G90G28.1______

It may work also with a G28_____axis move information

Try a regular G-Code move and see if it works it may be a setup problem as well.
