This feature lets you stop a running program, jog away from the part, and then start the program again.

  1. Press FEED HOLD.

    Axis motion stops. The spindle continues to turn.

  2. Press X, Y or Z, then press HANDLE JOG. The control stores the current X, Y, and Z positions.
  3. note: You can jog only the X, Y, and Z Axes in this mode.
    The control gives the message Jog Away. Use the jog handle or jog keys to move the tool away from the part. You can command coolant with AUX CLNT or COOLANT. You can start or stop the spindle with CW, CCW, or STOP. You can also release the tool to change inserts.
  4. caution: When you start the program again, the control uses the previous offsets for the return position. Therefore, it is unsafe and not recommended to change tools and offsets when you interrupt a program.
    Jog to a position as close as possible to the stored position, or to a position where there is an unobstructed rapid path back to the stored position.
  5. Press MEMORY or MDI/DNC to return to run mode. The control continues only if you return to the mode that was in effect when you stopped the program.
  6. Press CYCLE START. The control gives the message Jog Return and rapids X and Y at 5% to the position where you pressed FEED HOLD. It then returns the Z Axis. If you press FEED HOLD during this motion, axis motion pauses and the control gives the message Jog Return Hold. Press CYCLE START to resume the Jog Return motion. The control goes into a feed hold state again when the motion is finished.
  7. caution: The control does not follow the same path that you used to jog away.
    Press CYCLE START again and the program resumes operation.
    caution: If Setting 36 is ON, the control scans the program to make sure the machine is in the correct state (tools, offsets, G- and M-codes, etc.) to safely continue the program. If Setting 36 is OFF, the control does not scan the program. This can save time, but it could cause a crash in an unproven program.
