Movement of tool rotary axis per revolution
7620
[Data type] 2-word
Input increment IS-A IS-B IS-C Unit
Rotary axis 0.01 0.001 0.0001 deg
[Valid data range] 1 to 9999999
This parameter sets the movement of a tool rotary axis per revolution.
Maximum allowable speed for the tool rotary axis (polygon synchronous
axis)

[Data type] Word
[Unit of data] min

[Valid data range] For polygon turning using servo motors:
1.2 × 10
8
0 to
Set value of the parameter No.7620
For polygon turning with two spindles:
Set a value between 0 and 32767, but which does not exceed the
maximum allowable speed, as determined by the performance of the
second spindle and other mechanical factors.
This parameter sets the maximum allowable speed of the tool rotary
axis (polygon synchronous axis).
If the speed of the tool rotary axis (polygon synchronous 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, synchronous
control between the spindle and tool rotary axis (polygon synchronous
axis) is lost. And, when the speed is clamped, P/S alarm No.5018 is
issued.
Allowable spindle speed deviation level in polygon machining with two
spindles

[Data type] Byte
[Unit of data] min
-1
[Valid data range] 0 to 255
[Standard setting value] 1 to 10
This parameter sets the allowable level of deviation between the actual
speed and specified speed of each spindle in polygon machining with
two spindles. (The value set with this parameter is used for both the
master axis and polygon synchronous axis.)
