The rotary axes consisting of:
● The two channel identifiers for the reference of the rotary axes V
The type of kinematics with one of the values T, P or M:
● Kinematics type T: Only tool can rotate.
● Kinematics type P: Only part can rotate.
● Kinematics type M: Tool and part can rotate.
Clearing the toolholder data
Data of all toolholder data sets can be deleted using $TC_CARR1[0]=0.
The kinematic type $TC_CARR23[T]=T must be assigned with one of the three permissible
upper or lower case letters (T,P,M) and for this reason, should not be deleted.
Changing the toolholder data
Each of the described values can be modified by assigning a new value in the part program.
Any character other than T, P or M results in an alarm when an attempt is made to activate
the toolholder that can be orientated.
Reading the toolholder data
Each of the described values can be read by assigning it to a variable in the part program.
Fine offsets
An illegal fine offset value is only detected if a toolholder that can be orientated is activated,
which contains such a value and at the same time setting data
SD42974 $SC_TOCARR_FINE_CORRECTION = TRUE.
The maximum permissible fine offset is limited to a permissible value in the machine data.
