(6) Move the cursor to "Zero-P" with
the [ ↑ ] and [ ↓ ] keys.
Enter the value in the input area and
press the [INPUT] key. (*2)
(7) Move the axis toward the machine end
stopper.
(8) Press the axis against the machine
end stopper.
(9) The current limit is reached continually
during the given time period.
(10) Move the axis in the counter direction.
(11) The axis reaches the grid point
immediately before the stopper.
The zero point initialization is now complete. After initializing all axes, turn the power OFF and ON.
*1 If "#2059 zerbas = 0 (position where the axis was stopped in the stopper method (grid point immediately before
stopper = machine end stopper))" is set, the axis will stop automatically at the procedure (9) without moving in the
opposite direction. The condition will be as follows:
State: [Complete], Machine end: 0.000, Machine position: Current machine position.
*2 The operation order is slightly different when "#2059 zerbas = 1 (grid point just before stopper)" is set. Set the
procedure (6) "Zero-P" after "Complete" is displayed on "State" of the procedure (11).

- (7) to (11) in this diagram correspond to the operation procedure.
- Select either one of "#2 Zero-P" with the parameter.
