4.11 Work offset

Note
The functions of HMI Embedded can be altered in the INI files, display machine
data or the user interface.
4.11.1

Changing access protection to Base Offset softkey

Parameters operating area
The display machine data
MD 9247: MM_USER_CLASS_BASE_ZERO_OFF_PA can be used to set the
access level from which the "Base WO" softkey is displayed in the "Work offset"
window in the Parameters operating area.
At the same time, the base frames are also shown/hidden in the "Work offset"
window and in the "Active WO + offsets" window.
Machine operating area
The display machine data MD 9248: MM_USER_CLASS_BASE_ZERO_OFF_MA
can be set to select the access level from which "WO base" softkey is displayed in
the "Scratching" screen in the Machine operating area and/or G500 can be entered
in the work offset field.
4.11.2

Fine work offset and base offset

This function refers to the offset in the screen form "Settable work offset" and
"Base work offset".
Another column for the fine offset is inserted alongside the column for entering the
offsets.
The inputs will be validated using the display machine data
•
MD 9203: USER_CLASS_WRITE_FINE
•
MD 9451: MM_WRITE_ZOA_FINE_LIMIT
The first data describes the protection level, and the second data the amount of a
possible value that can be entered.
The base work offset (base WO) is displayed like a settable work offset and can be
selected and modified using the "Base WO" softkey in the screen form "Overview
of work offsets".
The general machine data MD 18600: MM_FRAME_FINE_TRANS = 1 activates
the fine offset for all settable FRAMES and the base frame.
