- 341 -
Control axis number of tool rotation axis for polygon turning
7610
[Data type] Byte
[Valid data range] 1, 2, 3, . . . number of control axes
This parameter sets the control axis number of a rotation tool axis
used for polygon turning.
Movement of tool rotation axis per revolution
7620
[Data type] 2-word
Input increment IS-A IS-B IS-C Unit
Rotation axis 0.01 0.001 0.0001 deg
[Valid data range] 1 to 9999999
This parameter sets the movement of a tool rotation axis per
revolution.
Maximum allowable speed for the tool rotation axis (polygon
synchronization axis) 7621
[Data type] Word
[Unit of data] min
-1
[Valid data range] 0 to 1.2 × 10
8
/ Set value of the parameter No.7620
This parameter sets the maximum allowable speed of the tool rotation
axis (polygon synchronization axis).
If the speed of the tool rotation axis (polygon synchronization axis)
exceeds the specified maximum allowable speed during polygon
turning, the speed is clamped at the maximum allowable speed. When
the speed is clamped at a maximum allowable speed, however,
synchronization between the spindle and tool rotation axis (polygon
synchronization axis) is lost. And, when the speed is clamped, P/S
alarm No.5018 is issued.
Multiplier influencing the slave spindle speed
7635
[Data type] Byte
[Unit of data] Slave spindle (min
-1
)/master spindle (min
-1
)
[Valid data range] 1 to 9
Set up a multiplier that will act on the distance through which the
slave spindle is to move.
In speed ratio control, the relationship between the speeds of the
spindles is:
Slave spindle speed = master spindle speed ×
