14.2 Related to general machine parameters
These variables are read-only (R) synchronous and are evaluated execution time.
They have generic names.
• Replace the "x" letter with the axis number.
• Replace the letters "i" and "m" with numbers keeping the brackets.
The PLC reading of TORQDIST , PRELOAD , TPROGAIN and TCOMPLIM comes in hundredths
(x100). Ver "Access to numeric values from the PLC" en la página 358.
