32.3 Deceleration Check for Opposite Direction Movement Reversal

Deceleration check cannot be designated for G01 -> G00 or G01 -> G01, 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 G01 -> G00 opposite direction movement reversal
If the axis movement reverses to the opposite direction in a G01 to G00 successive block, the deceleration check
for the movement in the opposite direction can be changed with the base specification parameter G01 -> G00
deceleration check (#1502 G0Ipfg).
#1502 = 0
