MD : SCALING_FACTORS_USER_DEF[n] * internal unit
Enter the actual value corresponding to the approached position in MD 10230:
SCALING_FACTORS_USER_DEF[n].

Example 1:
Machine data input/output of the linear velocities is to be in m/min instead of
mm/min (initial setting). The internal unit is mm/s.
MD 10220: 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:
MD : SCALING_FACTORS_USER_DEF[n] +
MD : SCALING_FACTORS_USER_DEF[n] +
å MD : SCALING_FACTORS_USER_DEF[2] + 16.667
Index 2 specifies the "linear velocity" (see above).
Example 2:
In addition to the change of example 1, the machine data input/output
of linear accelerations, is to be performed in ft/s
2
internal unit is mm/s ).
