2.3 Absolute Position Setting Screen
2.3.2 Carrying Out Dogless-type Zero Point Initialization
Procedures (Machine end stopper method : manual method)
Set the following parameter beforehand in the "Abs.Posit.Param." screen.
Parameter
Setting value
#2049 type (absolute position detection type) 1 (machine end stopper method is selected)
#2054 clpush (current limit) 0 to 100
#2059 zerbas (zero point return parameter) 1 (on the grid point immediately before the stopper)
The parameters other than "#2049 type" can be set in the "Zero point set" screen.
(1) Select the axis that "#2049 type" is "1". Refer to "2.3.1 Selecting the Axis" for procedures to select
the axis.
(2) Select the HANDLE mode or JOG mode.
(3) Input "1" to "Absolute posn set". The input value appears at "Absolute posn set".
(4) Input an arbitrary value to "#2 Zero-P". The input value appears at "#2 Zero-P".
(5) Move the axis toward the machine end
stopper.
-> a
State : [Stopper]
Machine end : Distance between stopper and grid point
Machine posn : [Not passed] -> current machine position
(6) Hit against the machine end stopper.
-> b
State
: [Stopper]
The current has reached its limit for given
time.
-> c
State
: [Release]
(7) Move the axis in the counter direction.
-> d
State
: [Ret. Ref. P.]
The axis has reached the grid point
immediately before the stopper.
-> e
State
: [Complete]
This completes zero point initialization. Turn the power OFF
and ON after the initialization for all axes.
