9.3 Application of OEM Cycles
Illegal functions
Q parameters with
special meanings
December 2001
An OEM cycle is a HEIDENHAIN conversational program with variables called
Q parameters. You write and test the program on the TNC. You define the
numbers of the transfer parameters in the OEM cycle and in CycleDesign. The
Q parameters Q200 through Q399 are reserved as transfer parameters for the
OEM cycles. Up to NC software 280 474-xx, a maximum of 20 transfer
parameters are allowed per cycle. Starting with 280 476-01, 32 are allowed.
Note
The Q parameters Q200 to Q336 are used by the HEIDENHAIN standard
cycles. Always use the same parameter number for identical parameter
functions!
You will find detailed information about programming with Q parameters in the
User's Manual.
The following functions are not permitted in OEM cycles:
n
M functions M02, M30, M06 with program stop
n
Programmed STOP block
n
Program calls with PGM CALL
n
Definition of Cycle 14 "Contour Geometry"
Cycle 14 "Contour Geometry" must be defined in the main program.
Q parameters Q100 to Q199 are reserved for special functions of the TNC.
Some of them have a specific meaning, such as tool radius, tool axes, etc.
You will find a description of these Q parameters in the User's Manual.
