⇒ 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:
In addition to the change in Example 1, the machine data input/output of linear accelerations
must be in ft/s
(The internal unit is mm/s
Index 4 defines the "linear acceleration" in the "Scaling factors of physical quantities" list.

The scaling factor for the linear velocities is to differ from the standard setting. For this,
in machine data:
MD10220 $MN_SCALING_USER_DEF_MASK
bit number 2 must be set.
⇒ MD10220 $MN_SCALING_USER_DEF_MASK = 'H4'; (bit no. 2 as hex value)
