Press the “Machine” key on the PPU.
Press the “Prog. cont.” SK on the PPU.
Press the “Dry run feedrate” SK on the

Make sure the feedrate override on the MCP is 0%.
Press “Door” on the MCP to close the

Step 2
Before executing the “Dry Run”, please
change the offset value appropriately for the
real workpiece size in order to avoid cutting
the real workpiece during the dry run and
avoid unnecessary danger!
After finishing the dry run, please turn the changed offset
back to the original value in order to avoid affecting the
actual machining!
