compensation can be executed when the positive/negative coordinate system of machine zero
moves
Operation during the positive coordinate:
the first compensation length is No. 000 set
compensation value during 【 Compensation X 】 , the second is that of No. 001 and the N is that of
No. N-1.
Operation during the negative coordinate:
the first compensation length is No. 1000 set
compensation value during
【
Compensation X
】
, the second is that of No. 1001 and the N is that of
No. 1000+N-1.
