Detailed description

PROT
Several axis pairs can be defined with the "PROT" (compile cycle file CCPROT.ELF)
function, which are then protected against mutual collision.
2.1

Machine data

Switch on CC channel
The CC channel (compile cycle channel) is specifically activated in the machine data:
MD60972 $MN_CCACTIVE_IN_CHAN_PROT[2]
Defining axis pairs
All axis pairs are defined in the machine data:
MD61516 $MN_PROTECT_PAIRS[n]
The first axis is defined in the 1st and 10th decade and the second axis is defined in the
100th and 1000th decade.
"Free travel" direction of the axes
The concerned "Free travel" direction of the axes must be recorded in the machine data:
MD61517 $MN_CC_PROTECT_SAVE_DIR[n]
As in axis pair definition, the following is valid here too:
The first two decades are valid for the first axis of the pair, the next two decades for the
second axis.
A value greater than 0 means "free travel in the plus direction", the value 0 means "free
travel in the minus direction".
Zero point offest
A zero point offest between the first and second axes can be specified in the machine data:
MD61518 $MN_CC_PROTECT_OFFSET[n]
Special functions: Axis pair collusion protection (TE9)
