G2: Velocities, setpoint / actual value systems, closed-loop control
7.2 Velocities, traversing ranges, accuracies
⇒ The scaling factor is calculated using the following formula:
Index n defines the "linear velocity" in the "Scaling factors of physical quantities" list.
Example 2:
2
In addition to the change in Example 1, the machine data input/output of linear accelerations must be in ft/s
2
instead of m/s (initial state).

(The internal unit is mm/s .)
Index 4 defines the "linear acceleration" in the "Scaling factors of physical quantities" list.
