NOTE
When this parameter has been set, the power must be
turned off before operation is continued.

AOV Specifies whether to use automatic corner override, as follows :
0 : Not to use.
1 : Use.

Minimum deceleration ratio (MDR) of the inner circular cutting
rate in automatic corner override
[Data type] Byte
[Unit of data] %
[Valid data range] 1 to 100
Set the minimum deceleration ratio (MDR) in changing the inner circular
cutting feedrate by automatic corner override.
In circular cutting with an inward offset, the actual feedrate for a specified
feedrate (F) becomes as follows:
F
Rc
Rp
Rc: Radius of the path of the cutter’s center
Rp: Programmed radius
As the actual feedrate becomes the value obtained from the above
equation, the specified rate F can be achieved on the program path.

If Rc is too samall in comparison with Rp so that
Rc

80, the cutter will
stop. To prevent this, the minimum deceleration ratio (MDR) is set.
When
Rc

80,
the actural rate becomes as follows:
F × (MDR)
