28 Setting the Machine Error Compensation
28.3 Cyclic Error Compensation
28.3.3 Error Measurement
This function performs compensation based on the position deviation related to the machine zero. When measuring errors,
disable all types of compensation (such as pitch error compensation and backlash compensation), and also the functions
accompanied by the offset of the coordinate system such as workpiece coordinate system offset. Then start the measurement
with the start point of the error cycle matching the machine coordinate zero point.
For machines that configure the reference position shift distance "#2027 G28sft", first set #2027 prior to measuring the error.

28.3.4 Precautions
(1) The updates regarding the compensation amount of this function are immediately reflected to the operation. Note that
large compensation amounts might cause sudden machine vibration.
(2) This function starts compensating after the zero point is established.
When the zero point has not been established, this function is not available even if the parameter is set to Enabled.
(3) As changing the reference position shift distance "#2027 G28sft" changes the position of the machine coordinate zero
point, compensation amounts will need to be reconfigured in this case.
When the coordinate system offset has been performed for functions such as workpiece coordinate system offset and ref-
erence position #1 "#2037 G53ofs", it is not necessary to reconfigure the compensation amounts if each has already
been appropriately configured relative to the machine coordinate zero point.
(4) This function uses the same parameters as functions such as memory-type pitch error compensation when configuring
compensation amounts (#4101-#5999). Ensure that no parameters are set incorrectly.
(5) When the settings used exceed the parameter setting range in "Cyclic error compensation: initial number of compensa-
tion" (#2586 Cycstnum) and "Cyclic error compensation: number of divisions" (#2587 Cycdv), the compensation config-
ured for the axis is not enabled.
(Example) Compensation start No. is 5995, and step No. is 16. (exceeds the range of parameter number, #5999)
