Detailed Description
2.1 Velocities, traversing ranges, accuracies
⇒
⇒ The scaling factor is calculated using the following formula:
Index 2 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
is to be performed in ft/s
(The internal unit is mm/s
Index 4 defines the "Linear acceleration" in the "Scaling factors of physical quantities" list.
2-10
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)
, instead of m/s
