Overview: Record selection (positioning record) – control interface – operating mode
6.3
Relative positioning
The motor controller calculates internally with 65536 increments (16 bit) per revolution (360°). For
positioning tasks that do not have a whole number (integer) as the result, the motor controller rounds
up to the next whole number. This can result in deviations when positioning.
Example: Rotary indexing table
4 positions. (90°) 65536:4= 16384 ----> Integer
6 positions. (60°) 65536:6= 10922.666 ----> The controller positions at 10923 (60.0018°).
