4.DESCRIPTION OF PARAMETERS B-63950EN/02
- 360 -
7621 Maximum allowable speed for the tool rotation axis for polygon turning
NOTE
When this parameter is set, the power must be
turned off before operation is continued.
[Input type] Parameter input
[Data type] 2-word path
[Unit of data] min
-1
[Valid data range] 0 or positive 9 digit of minimum unit of data (refer to the standard
parameter setting table (B) )
(When the increment system is IS-B, 0.0 to +999999.999)
This parameter sets the maximum allowable speed of the tool rotation
axis.
NOTE
If the speed of the tool rotation axis exceeds the
set maximum allowable speed during polygon
turning, the synchronization between the spindle
and tool rotation axis is lost, and operation stops
with alarm PS5018.
7631 Allowable spindle speed deviation level in spindle-spindle polygon turning
[Input type] Parameter input
[Data type] Word path
[Unit of data] min
-1
[Valid data range] 0 to 99999999
This parameter sets the allowable level of deviation between the actual
speed and specified speed of each spindle in spindle-spindle polygon
turning. The value set with this parameter is used for both the master
axis and polygon synchronization axis.
When 0 is set in this parameter, the specification of 8 [min
-1
] is
assumed.
7632 Steady state confirmation time duration in spindle polygon turning
[Input type] Parameter input
[Data type] Word path
[Unit of data] msec
[Valid data range] 0 to 32767
This parameter sets the duration required to confirm that both spindles
have reached their specified speeds in spindle-spindle polygon
turning.
If the state where the speed of each spindle is within the range set with
parameter No.7631, and has lasted at least for the duration specified
with parameter No.7632, the spindle polygon speed arrival signal
PSAR <Fn063.2> is set to 1.
When 0 is set in this parameter, the specification of 64 [msec] is
assumed.
