Siemens SINUMERIK 840Di Function Manual page 383

The following applies:
Selected input/output unit = MD10230 * internal unit
The selected input/output unit is input into machine data:
MD10230 $MN_SCALING_FACTORS_USER_DEF[n],
expressed in internal units of 1 mm, 1 degree or 1 s.
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)

Velocities, Setpoint/Actual-Value Systems, Closed-Loop Control (G2)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
The scaling factor for the linear velocities is to differ from the standard setting. In this case, bit
number 2 must be set in machine data:
MD10220 $MN_SCALING_USER_DEF_MASK.
⇒ MD10220 $MN_SCALING_USER_DEF_MASK = 'H4'; (bit no. 2 as hex value)
2.1 Velocities, traversing ranges, accuracies
