When the product of the specified interpolation speed and override value
exceeds the maximum interpolation feed rate for the axis being moved by circu-
lar interpolation (set in the system parameters), circular interpolation will be per-
formed at the lowest maximum feed rate among the axes being moved. For
example, consider the following situation.
G02 X100
X-axis override value:
X-axis max. interpolation feed rate:
Y-axis max. interpolation feed rate:
Interpolation speed after override calculation
The interpolation speed of 3000 [mm/s] exceeds the maximum interpolation
feed rate for the Y-axis (2000 [mm/s]), so the interpolation speed is set to 2000
[mm/s].
Note When the radius exceeds 9,999,999 pulses, circular interpolation will be per-
formed within the specified circle. Keep the radius under 9,999,999 pulses when
performing high-precision circular interpolation.
When an optional number is specified, the axis movement command will be car-
ried out when that optional input goes ON. The operation won't be performed
until the optional input goes ON. The source of the optional input depends on the
optional number specified, as shown below.
