[Pr.41] Allowable circular interpolation error width
For Allowable circular interpolation error width, set the allowable error range of the calculated arc path and end point address.
If the error of the calculated arc path and end point address is within the setting range, circular interpolation is performed to
the set end point address while the error is compensated with spiral interpolation.
The allowable circular interpolation error width is set in the buffer memory addresses of the reference axis.
In the circular interpolation control using the center point specification, the arc path calculated with the start point address and
center point address and the end point address may deviate.
■
Buffer memory address
The following table shows the buffer memory address of this area.
■ Setting range
The setting range depends on the setting of [Pr.1] Unit setting.
*1 When this buffer memory area is set with programs, a calculation is performed in the RD75 to convert a setting value to the value in
each unit. For setting this buffer memory area, take the value after the unit conversion into consideration.
■
Default value
The default value is 100 for all the axes.
