basis. The unit is mm/sec2 or inch/sec2, depending on the
machine unit. A value of between 0 and 99999.999 can be set.
Acceleration change time (bell-shaped) (ACC CHANGE
TIME(BELL))
This item specifies the acceleration time required to reach the
maximum acceleration value of bell-shaped
acceleration/deceleration before interpolation. The value set in
this item is also used as a deceleration time required to reach an
acceleration value of 0 from the maximum acceleration value.
The unit is msec, and a value of between 0 and 200 can be set.
Maximum acceleration (MAX ACCELERATION)
This item specifies an allowable acceleration value to be used in a
curvature area such as circular curves and very small straight lines.
The unit is mm/sec2 or inch/sec2, depending on the machine unit.
A value of between 0 and 99999.999 can be set.
Time constant for acceleration/deceleration after interpolation
(T-CONST AIPL ACC/DEC)
This item specifies an acceleration time required to reach a
feedrate specified for acceleration/deceleration after interpolation.
The unit is msec, and a value of between 0 and 4000 can be set.
Corner feedrate difference (CORNER FEED)
When the feedrate difference between two blocks exceeds the
value set in this item, the tool is decelerated at the corner to
prevent the value set in this item from being exceeded. The unit is
mm/sec or inch/sec, depending on the machine unit. A value from
0 to 999999.999 can be set.
Feed-forward coefficient (FEED FORWARD COEFFICIENT)
This item specifies a coefficient used for feed-forward control. A
value fr8om 0.00 to 100.00(%) can be set.
