1 Prec On

[Explanation]
(1) The high accuracy mode is enabled using the Prec On instruction if it is desired to perform interpolation
movement with increased path accuracy.
(2) When this instruction is used, the path accuracy is improved but the program execution time (tact time)
may become longer because the acceleration/deceleration times are changed internally.
(3) The enabling/disabling of the high accuracy mode is activated from the first interpolation instruction after
the execution of this instruction.
(4) The high accuracy mode is disabled if the Prec Off or End instruction is executed, or a program reset
operation is performed.
(5) The high accuracy mode is disabled immediately after turning the power on.
(6) The high accuracy mode is always disabled in jog movement.
