5.6.16 CALC (calculate)
A value in the accumulator variable, previously read by a function such as GAP (get axis parameter) can be
modified with this instruction. Nine different arithmetic functions can be chosen and one constant operand
value must be specified. The result is written back to the accumulator, for further processing like
comparisons or data transfer.
