The following applies:
Input/output unit selected=
MD: SCALING_FACTORS_USER_DEF[n] * internal unit
In MD10230 SCALING_FACTORS_USER_DEF[n], the selected I/O device must be entered
expressed in the internal units mm, 1 degree and 1 sec.

Example 1:
Machine data input/output of the linear velocities is to be in m/min instead of mm/min (initial
state). The internal unit is mm/s.
MD10220 SCALING_USER_DEF_MASK bit2 = 1 is used to enter the scaling factor for linear
velocities as a user-defined value.
The scaling factor is calculated using the following formula:
