B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 87 -
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000
Set the time constant used for exponential acceleration/deceleration in
the thread cutting cycle (G76, G78 (G92 in G code system A)) for
each axis.
If the acceleration type is not exponential acceleration/deceleration,
parameter No. 1622 becomes valid.
FL rate of exponential acceleration /deceleration in the thread cutting cycle
for each axis 1627
[Data type] Word axis

Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Set the lower limit (FL rate) of exponential acceleration/deceleration
in the thread cutting cycle (G76, G78 (G92 in G code system A)) for
each axis.
