However, the FN 17:SYSWRITE ID 622 function offers you the possibility of
numbering all the cuts of an NC program, making a permanent assignment
possible. This is considered in the Program Run, Single Block operating
mode, and you can retroactively carry out the learning process for individual
cuts.
You must deactivate the execution of the given M-function macros for this.
The definition of the beginning and end of a cut via the FN 17:SYSWRITE ID
622 function must then occur separately for each cut in the NC program.
Through a changed algorithm, the CC 61xx achieves a lower drive utilization
for synchronous and linear motors, provided that the stall current (I-0) is higher
than the rated current (I-N) of the motor in the motor table. As a result, the use
of automatic feed control (AFC) attains higher milling power. Compatibility
mode:
If AFC reference values that were recorded with the CC 424(B) or CC 422 are
to be used with the CC 61xx, then you can switch to the old algorithm over
MP2221 bit 10.
MP7246 Machine parameter with multiple function
Input: Bit 3 – Settings file for AFC
0: Do not generate settings file for AFC
1: Generate settings file for AFC
MP2221.x Handling of linear and synchronous motors to attain higher
milling power with AFC
Input: 0: Handling for attaining higher milling power is active
1: Handling for attaining higher milling power is not active
The M-function macros for M3, M4 and M5 (as listed above) are used to
write the control settings for the various cuts sequentially, in the same
order as the cuts in the NC program, into the <NC name>.H.AFC.DEP file. You
cannot use these M-function macros to assign a permanent number to the
individual cutting data blocks.
This means that you cannot use the Program Run, Single Block operating
mode to perform a teach-in cut for just a single cut.
You must always run the entire NC program so that AFC can update the
correct lines in <NC name>.H.AFC.DEP.
You cannot use just any numbers when numbering the cuts in the NC
program. The beginning of the first cut must
be started after M3 or M4 with FN 17:SYSWRITE ID 622 NR0 IDX 0.0 =+1
and be ended before M5 with FN 17:SYSWRITE ID 622 NR0 IDX 0.0 =+0.
NR must be incremented for each further cut. Targeted access to individual
cutting data blocks is only possible with sequential numbering.
