- 1292 -
1420 Rapid traverse rate 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 the rapid traverse rate when the rapid traverse override is 100% for
each axis.
1620
Time constant T or T1 used for linear acceleration/deceleration or
bell-shaped acceleration/deceleration in rapid traverse for each axis
[Input type] Parameter input
[Data type] Word axis
[Unit of data] msec
[Valid data range] 0 to 4000
Specify a time constant used for acceleration/deceleration in rapid
traverse.
