P5-84 = N / (π * d2 (mm) ) * L (mm), (pulses required by L)
P5-83 = 1
P5-95.H (in Hexadecimal) = A * C
P5-95.L (in Hexadecimal) = B
P5-96 = L (mm) / (π * d1 (mm) ) * C * Vc * 1000000
Vc = Speed compensation, Vc = 1, Do not compensate.
Vc = 0.9, Slow down to 90%, Vc = 1.1, Speed up to 110% .

Step 5: When all relevant parameters are set, write 7 to P5-97 to enable Macro 7. After it is
enabled, read the same parameter P5-97 again, if the value is 0x1007, it means this table is
created by macro successfully. If any error code occurs, please modify the parameter
according to the error message.
