This item is used to set up a linear–portion acceleration for
pre–interpolation acceleration/deceleration (in mm/s
2
).
Setting range: 50.000 to 99999.999 (mm/s
2
)
Size: 2–word type
The parameter value set up on the machining parameter tuning screen is
saved to the following parameters:
No. 13610: Velocity–first parameter
No. 13611: Precision–first parameter
In addition, the following parameters are set up from the precision level:
No. 1770/1771 (arbitrary integral ratio)
Effective value =
No.1770
No.1771
100
6
(arbitrary integral ratio for
millimeter machines)
No. 1770: Maximum allowable machining rate for pre–interpolation
linear acceleration/deceleration (in mm/min)
No. 1771: Time elapsed before the maximum allowable machining
feedrate for pre–interpolation linear acceleration/
deceleration is attained (in ms)

NOTE
The acceleration setting is common to all axes.
This item is used to set up a time constant for the bell–shaped portion of
pre–read pre–interpolation acceleration/deceleration (in ms).
Setting range: 0 to 100 [ms]
Size: Byte type
The parameter value set up on the machining parameter tuning screen is
reflected on the following parameters:
No. 13612: Velocity–first parameter
No. 13613: Precision–first parameter
In addition, the following parameter is set up according to the precision
level:
(AI contour control)
No. 1772: Bell–shaped acceleration/deceleration time constant with
a constant pre–read pre–interpolation acceleration time (in ms)
If this item is set with a nonzero value, the following parameter is also set
up:
BEL (bit 7 of parameter No. 1603) = 1 (AI contour control only)
