Physical unit MD10220:
Bit number
MD10230:
Index n
Kv factor 9 9
Rev. feedrate 10 10
Compensation value linear position 11 11
Compensation value angular position 12 12
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.
MD10220 $MN_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:

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
are to be performed in ft/s
2
instead of m/s
2
(default setting). (the internal unit is mm/s
2
).
