K3: Compensations
5.4 Interpolatory compensation
Compensation parameters
● Starting position: -400.0
● End position: 400.0
● Distance between interpolation points: 8.0
Number of interpolation points
MD18342 $MN_MM_CEC_MAX_POINTS[ 0 ] = (400.0 - (-400.0)) / 8.0 + 1 = 101
The memory required in the static user memory is at least 808 bytes (8 bytes per compensation
value).
