4. AUTOMATIC OPERATION
Be sure to specify the radius of an arc with R.
If an end point is not correctly placed on an arc (if a leading
line is produced) when an arc center is specified using I, J,
and K, the nozzle does not perform correct reverse
1. Never initiate an interrupt during reverse movement.
2. Never perform reverse movement for an interrupte block and the
program that has issure the interrupt.
If the operation mode is switched after a single block stop from memory
operation to MDI operation or vice versa during reverse movement or
forward return movement, reverse movement, forward return movement,
and forward movement can no longer be performed. To restart operation,
return the mode to the original mode, then press the cycle start switch.
When the nozzle is positioned based on nonlinear interpolation by setting
bit 1 (LRP) of parameter No. 1401 to 0, the path of the beam for reverse
movement does not match the path for forward movement. The path for
forward return movement is the same as the path for forward movement.
When the nozzle is positioned based on linear interpolation by setting bit
1 (LRP) of parameter No. 1401 to 1, the path of the beam for reverse
movement matches the path for forward movement.

The dwell command (G04) is executed in reverse movement and forward
return movement in the same way as during ordinary operation.
A cutter compensation value, parameter, pitch error data, workpiece zero
point offset value, setting specified or modified using the programmable
data setting code (G10) are ignored in reverse movement and forward
The on/off state of the stored stroke check function present at the end of
forward movement remains unchanged during reverse movement and
forward return movement. This means that the actual on/off state may
differ from the modal G22/G23 indication. When reverse movement or
forward return movement is cancelled upon reset, the modal G22/G23
indication at that time becomes valid.
The setting of an area with G22 X_Y_Z_I_J_K at the end of forward
movement remains unchanged.
