6.16.3 Deceleration Check when Opposite Direction Movement is Reversed
Deceleration check cannot be designated for G1 → G0 or G1 → G1, but it can be designated in the
following manner only when the movement reverses to the opposite direction in successive blocks.
Deceleration check can also be executed if even one axis is moving in the opposite direction while
several axes are interpolating.
(1) Designating deceleration check for G1 → G0 opposite direction movement reversal
If the axis movement reverse to the opposite direction in a G1 to G0 successive block, the
deceleration check for the movement in the opposite direction can be changed with the base
specification parameter G1 → G0 deceleration check (#1502 G0Ipfg).

G0Ipfg:1
(2) Designating deceleration check for G1 → G1 opposite direction movement reversal
If the axis movement reverse to the opposite direction in a G1 to G1 successive block, the
deceleration check for the movement in the opposite direction can be changed with the base
specification parameter G1 → G1 deceleration check (#1503 G1Ipfg).
