Help with a Fanuc OT - dry run

Hi, i'm new to this forum.

We have a Miyano lathe machine with Fanuc OT controller. we have a problem we cannot run axies in automatic mode while spindle is on (M03 S1500) until we turn on the dry run. When we try to run a interpolation (like G1, G2 or G3) the axis don't move just with dry run activated.


I wish you can help me to solve my problem.

..check Clamping for Chuck...Inside or Outside Safety switch.

also, check in the screen the actual rpm. if you dont have rpm the spindle encoder may be bad.
