- 84 -
1627 FL rate for acceleration/deceleration in threading cycles for each axis
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm/min, inch/min, degree/min (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (C)
(When the increment system is IS-B, 0.0 to +240000.0)
Set an FL feedrate for acceleration/deceleration after interpolation in
the threading cycles G92 and G76 for each axis. Set 0 at all times
except in a special case.
1660
Maximum allowable acceleration rate in acceleration/deceleration before
interpolation for each axis
[Input type] Parameter input
[Data type] Real axis
[Unit of data] mm/sec/sec, inch/sec/sec, degree/sec/sec (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (D)
(When the machine system is metric system, 0.0 to +100000.0. When
the machine system is inch system, machine, 0.0 to +10000.0.)
Set a maximum allowable acceleration rate in acceleration/
deceleration before interpolation for each axis.
If a value greater than 100000.0 is set, the value is clamped to
100000.0.
If 0 is set, the specification of 100000.0 is assumed. If 0 is set for all
axes, however, acceleration/deceleration before interpolation is not
performed.
If a maximum allowable acceleration rate set for one axis is greater
than a maximum allowable acceleration rate set for another axis by a
factor or 2 or more, the feedrate at a corner where the direction of
travel abruptly changes can decrease temporarily.
