14.3.1 Related to gear parameters
These variables may be accessed from the program (PRG), PLC and interface (INT), they are
read-only (R) synchronous and are evaluated in execution time.
They have generic names.
• Replace the "n" character with the channel number, maintaining the brackets. The first
channel is identified with the number 1, "0" is not a valid number.
• Replace the letter "g" with a gear number keeping the brackets. The first gear is identified
with the number 1, "0" is not a valid number.
• Replace the "Xn" character by the name, logic number or index in the channel of the axis or
of the spindle.
