6.20.3 Deceleration Check When Opposite Direction Movement Is Reversed
As is mentioned in "(3) Designating deceleration check" in the section "Function", 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 reverses 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:0
G0Ipfg:1
(2) Designating deceleration check for G1 -> G1 opposite direction movement reversal
If the axis movement reverses 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).
