SINUMERIK 802D sl Operation and Programming Nibbling (BP-N), 06/2006 Edition
6FC5 398-3CP10-0BA0
Programming example
N10 ACC[X]=80 ; 80% acceleration for the X axis
...
N100 ACC[X]=100 ; Disable override for the X axis
Activation
The limitation is in effect with all types of interpolation in the AUTOMATIC and MDA modes,
but not in the JOG mode and when approaching the reference point.
The value assignment ACC [...] = 100 deactivates the override (100% of the MD values) as
well as RESET and program end.
The programmed override value is also active with dry run feedrate.
Caution
A value greater than 100% may only be programmed if this load is permissible for the machine
mechanics and the drives have the corresponding reserves. Failure to adhere to the limits can
lead to damage to the mechanical parts and/or error messages.
8.3.14 Traversing with feedforward control: FFWON, FFWOF
Functionality
The feedforward control reduces the following error in the traversed path towards zero.
Traversing with feedforward control provides higher path accuracy and thus better manufac-
turing results.
Programming
FFWON ; Feedforward control ON
FFWOF ; Feedforward control OFF
Programming example
N10 FFWON ; Feedforward control ON
N20 G1 X... Z... F900
...
N80 FFWOF ; Feedforward cotnrol OFF
