Danger
After the actual value has been reset, none of the protection zones or
software limit switches are operative! Only after another reference
point approach are the protection zones and software limit switches
active again.
Further information
A new position value is entered for the current axis positions.
Please refer to the information and specifications provided by the
machine manufacturer.
Operating sequence
"Jog" mode is selected in the "Machine" operating area.
The "Preset" window appears on the screen.
Enter the new actual value, which must in the future correspond to the
current axis position for each individual axis. By doing so, you are
redefining the control zero in the MCS. When the control zero is
redefined, the tool change point, for example, also changes.
Further information
The "Preset" function can be disabled by means of protection levels
(keyswitch position).
Function
The "Set actual value" function sets the workpiece coordinate system
to a defined actual coordinate and calculates the resultant offset
between the old and a newly entered actual value in the WCS in the
1st basic offset.
The "Set actual value" function can only be used if the control is in the
workpiece coordinate system.
The functions are stored under the same softkey.
