DIN/ISO programs of predecessor controls
The DIN program formats of the predecessor controls MANUALplus
4110 and CNC PILOT 4290 differ from the format of the MANUALplus
620. However, you can use the program converter to adapt programs
of the predecessor control to the new control.
When opening an NC program, the Steuerung 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.
Remember the following when converting DIN programs of the CNC
PILOT 4290:
 Tool call (T commands of the TURRET section):
 T commands containing a reference to the tool database are left
unchanged (example: T1 ID"342-300.1").
 T commands containing tool data cannot be converted.
 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.
