6.16 Deceleration Check

(4) Deceleration check in G1
→
G0, G1
→
G1 opposite direction movement reversal during
high-speed machining mode
• When the axis movement reverses to the opposite direction in a G1
→
G1 successive block during
the high-speed machining mode, the commanded deceleration will not take place even if G1Ipfg is
set to 1. Note that the G0Ipfg setting will be followed if the axis direction reverse to the opposite
direction in a G1
→
G0 successive block.
(5) Deceleration check in movement including spindle/C-axis
• The deceleration check in a movement command including the spindle/C-axis is as the table
described below when the following condition is fulfilled.
When the different values are set for the position loop gain in non-cutting mode (spindle parameter
#3203 PGCO) and the position loop gain in cutting mode (spindle parameter #3330 PGC1 to
#3333 PGC4).
That is because a vibration and so on occurs in the machine when the gain is changed during the axis
movement.

(Note 1) When G1 command is issued, the in-position check is performed regardless of the
deceleration check parameter.

cancel command
• The deceleration check in polar coordinate interpolation / milling interpolation / cylindrical start /
cancel command are as follows.
