3: a maximum of three polynomials can be programmed at
the same time; polynomials up to 3rd degree
Ref_value
Reference value from which the offset is derived
Length1_2_3
Wear parameter into which the tool offset value is added
Channel
Number of channel in which the tool offset is activated; specified only if
the channel is different to the present one
Spindle
Number of the spindle on which the online tool offset acts; only needs to
be specified for inactive grinding wheels
