Configure two axes as a tandem axis.
9.3.4 Tandem related variables.
Variables related to general machine parameters.
These variables are read-only synchronous and are evaluated during block preparation.
They have generic names. Replace the letter "nb" with numbers, keeping the brackets.
Tandem related variables.
These variables are read/write (R/W) synchronous and are evaluated during execution. They
correspond to linear and rotary axes and to the spindle. The mnemonics of the variables have
generic names.
• Replace "Xn" with the name or logic number of the axis.
• Replace the "ch" character with the channel number, maintaining the brackets.
(V.)A.TPIOUT.[Xn] (V.)A.TPIIN.[Xn]
The axis must be a valid tandem master, otherwise, it returns a value of zero.
(V.)A.TORQUE
The PLC reading of this variable comes in tenths (x10).
