DIN/ISO programs of predecessor controls
The formats of the DIN/ISO programs of the predecessor controls
MANUALplus 4110 and CNC PILOT 4290 differ from that of the
MANUALplus 620. However, you can use the program converter to
adapt programs from the predecessor controls to the new one.
When opening an NC program, the control recognizes the programs of
predecessor controls. The program concerned will be converted after
a confirmation prompt. "CONV_..." will be prefixed to the program
name.
The converter is also part of the Transfer function (Organization mode
of operation).
DIN/ISO programs not only have new solutions for tool management,
technology data, etc., but also for contour description and variable
programming.
Remember the following when converting DIN/ISO programs of the
MANUALplus 4110:
 Tool call: The loading of the T number depends on whether the
program is a "multifix program" (2-digit T number) or "turret program"
(4-digit T number).
 2-digit T number: The T number is loaded as "ID" and entered as
the T number "T1".
 4-digit T number (Tddpp): The first two digits of the T number (dd)
are loaded as "ID" and the last two (pp) as "T".
 Workpiece-blank definition: A G20/G21 workpiece-blank
definition of the 4110 becomes an AUXILIARY BLANK.
 Contour descriptions: In MANUALplus 4110 programs, the fixed
cycles are followed by the contour description. During conversion
the contour description is converted to an AUXILIARY CONTOUR.
The associated cycle in the MACHINING section then refers to this
auxiliary contour.
 Variable programming: Variable accesses to tool data, machine
dimensions, D compensation values, parameter data and events
cannot be converted. These program sequences have to be
adapted.
 M functions are left unchanged.
 Inches or metric: The converter cannot detect the unit of measure
of the MANUALplus 4110 program. Consequently, no unit of
measure is entered in the target program. This has to be completed
by the user.
