Describing the
mechanical offset
with tables
In order to manage several descriptions of the mechanical offset, e.g. when
swivel heads are changed, the descriptions can be saved in tables. A
description is activated either by the PLC or the NC.
Two types of tables are required:
Assignment table
Each row corresponds to one description (row 0 = description no. 1, etc.). The
first column contains the line number. For each description (= row), the value
of MP7500 for the description is entered in column two. Keep in mind that the
value must be entered as a decimal number. The file name with its complete
path is entered in the third column.
Description tables
The description table contains the contents of machine parameters MP7510.x,
MP7520.x, MP7530.x and MP7550.x. The index x corresponds to the line
number.
Of course the MP7530 column may also contain formulas, such as
temperature compensation with M128, etc. (See “Temperature
compensation” on page 6 – 75). A formula for a permanently effective
temperature compensation may be entered in the TEMPCOMP column. (See
“Permanent temperature compensation” on page 6 – 75).
Working with the description of the mechanical offset in tables:

7 Enter the code word KINEMATIC= followed by the file name with its complete
path from the assignment table.
(e. g., KINEMATIC= PLC:\KINEMAT\KINELIST.TAB)

7 To create an assignment table: In program management, switch to the
desired directory and enter the name of the assignment table, including the
extension .TAB.

7 Activate the description table by transferring the row numbers from the
assignment table
• from the PLC with Module 9097
• from the NC with FN17: SYSWRITE ID290 NR1
7

7 You can ascertain the active description table in two ways:
• With the PLC you can use Module 9098 to ascertain the name of the
description table or the line number in the assignment table.
• With the NC you can use FN18: SYSREAD ID290 NR1 to ascertain the line
number in the assignment table.
