Compensation

The following compensations are considered while calculating the switching positions:
• Temperature compensation
• Sag compensation

16.6.4

Tool radius compensation (TRC)

As part of tool radius compensation, control-internal part program blocks (compensation
blocks) are inserted into the part program. With reference to the switching signal output, a
compensation block is always added to the next programmed part program block.

Continuous-path mode

Continuous-path mode
Although the CC_FASTON(), CC_FASTON_CONT() and CC_FASTOFF procedure calls must
be programmed in dedicated part program blocks, this will not lead to a drop in velocity while
continuous-path mode is active (G64, G641, ...).
Continuous-path mode (ADIS)
If in continuous-path mode with programmable rounding response (G641 ADIS) a part
program block is inserted in the part program, then the originally programmed switching
position is not reached and the switching signal output takes place nevertheless in the center
of the rounding block.
