7.3.3.2 Machine End Stopper Method Automatic Initialization
This method, with which the axis is pushed against the machine end stopper, is available when "INIT-SET" can be
selected for the operation mode. (Sequence programs are required.))
This method has the following features compared to the manual initialization method:
- The axis is pushed with the same conditions (feedrate, distance) each time, so inconsistencies in the zero point
position can be more reduced.
- Part of the operations are automated to simplify the zero point initialization.
(1)
Display [ABS SERVO MONITOR] screen from [TOOL PARAM].
(2)
Set the current (torque) limit value when the axis is pushed against the machine end stopper to the
parameter"#2054 clpush Current limit(%)". Also set the parameter "#2055 pushf Pushing speed" and "#2056 aproch
Approach point".
The setting values differ according to the machine specifications. Set the appropriate value in accordance with the
machine specifications.
(Note)
Setting the excessive value may cause damage to the machine, as well as the warning and alarm.
Setting too small value may cause the unsuccessful detection of stopper, because the system will identify
the machine's friction load.

Position where the axis
was stopped
The parameter "#2059 zerbas" decides the absolute position basic point.
0: Position where the axis was stopped
1: Grid point just before stopper (electrical basic position)
