NOTE:
The A.TOP file can be named something else by inputting a new name before pressing
the Write key in STEP 4. The file extension (.TOP) will automatically get added to the
new file name. For two turret machines, it is suggested that the parameters for each
turret be saved separately. For example, typing in FD
∅∅
∅∅
∅:UP.TOP;A, will save all param-
eters pertaining to the upper turret to a file called UP.TOP. If ;B is entered after the
filename, all parameters pertaining to the lower turret would be sent to the output
device.(Be sure tochange the file name.)
Special Notes for W-axis and LT machines.
There are two parameters that relate to interference distances on LT and W-axis machines.
These parameters ARE NOT saved during the A.TOP file OUTPUT process. Therefore it
is necessary to record these parameters and input them manually through the control.(in
metric mode)
LT machines Optional Parameter Long Word # 53
How to manually set this data.
1. Measure the physical distance between the spindle interference points. (spindle
nose B to spindle nose R). i.e. 500 mm is measured
2. SET 500,000 as the data for O.P.L.W. # 53. (Can only set one time.)
3. Add -460,000 to this value to bring it down to 40,000. At this point the spindles
should be moveable.
4. Add small positive values until the desired interference distance is reached. (i.e.
200000 = 2.000”) (Setting range is 40000 - 9999999)
W-axis machines
Do the same procedure for the W-axis interference distance with the exceptions of set
100,000 at step #2 and add –100,000 at step #3(on W-axis this value can be brought to zero).
The data for the W-axis interference is entered in O.P.L.W. # 45.
