6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.4 Axis-specific MD 1 (axial data 1)
• The ROD encoder is mounted onto the motor and the gearing is located between the
motor and the leadscrew:
I
m =
4p
Example 1: I = 0.2 inch; p = 1000; b = 2 × 10
Example 2: Same values as above, except b = 0.5 × 10
• A linear scale with EXE is used:
g
m =
4f
Example:
• A rotary axis is used:
360 degrees
m =
Example:
Should either of the values be greater than 100 000, both values must be divided by the same
divisor (e.g. one exponent of 10).
Recommendation: Reduce whenever possible
