4.6 REFERENCE POSITION SETTING WITH MECHANICAL
STOPPER
Overview
This function automates the procedure of butting the tool against a
mechanical stopper on an axis to set a reference position. The purpose
of this function is to eliminate the variations in reference position
setting that arise depending on the operator, and to minimize work
required to make fine adjustments after reference position setting.
Select the axis for which the reference position is to be set, then
perform cycle start. Then, the following operations are performed
automatically:
1. The torque (force) of the selected axis is reduced to make the
butting feedrate constant, and the tool is butted against the
mechanical stopper. Then, the tool is withdrawn a parameter-set
distance from the mechanical stopper.
2. Again, the torque (force) of the selected axis is reduced, and the
tool is butted against the mechanical stopper. Then, the tool is
withdrawn a parameter-set distance from the mechanical stopper.
3. The withdrawal point on the axis is set as the reference position.
Explanation
- Basic procedure for reference position setting with mechanical stopper
(1) First, set the parameters required for reference position setting
with mechanical stopper.
Parameter ZMIx (No.1006#5) Direction of reference
position setting
Parameter No.7181 Withdrawal distance
Parameter No.7182 Reference position setting
distance
Parameter No.7183 Butting feedrate 1
Parameter No.7184 Butting feedrate 2
Parameter No.7185 Withdrawal feedrate in
reference position setting
Parameter No.7186 Torque limit
(2) Select manual reference position return mode.
(3) By using a manual handle feed axis select signal, select the axis
on which the reference position is to be set.
(4) Perform cycle start.
This starts the cycle operation for reference position setting.
