7.5 Torsion compensation during high speed cycle cutting function
This function adds the compensation at the point of the command reversing sign during high speed I/F mode
(G05), This function is useful for the case that the reverse point of work piece has sharp drop because it is
easy to bend for the weakness.
This function works only during G05, different from normal backlash compensation function. And this function
forces the sum of compensation always to be zero during G05. Therefore this function can be use in case that
compensation value is changed every work piece, which is useful properties for the machining.
• This function is available from 9087 / 01, 9083/02.
• This function is available from 90A3 / 01 or 90A7 / 01.
7.5.1 Parameters
TAWAMI Torsion compensation during G05
1 : useful.
0 : is not useful. (Standard)
When Motion command (Mcmd) changes from the plus to the minus, the minus value is added.
When Motion command (Mcmd) changes from the minus to the plus, the plus value is added.
(This method is like to the backlash compensation.)
• Restrict Available only for High speed axis (No.2005#4=1)
only during High speed I/F (G05)
• Feature
Torsion compensation value is added to Error counter when the sign of latest Mcmd reverses against the
sign of the former Mcmd except Mcmd = 0.
********************************************************************************************************************
Following is reference only. Don’t set HSBLC to one for the future compatibility, because above Torsion
compensation is superset including below HSBLC=1.
HSBLC Backlash compensation function during G05 is
1 : Available.
0 : Not available.
• Restrict High-speed axis (No.2005#4 = 1) only
• Function
During G05, normal backlash compensation works at the moment when servo accepts backlash
compensation data from CNC. The other side, this function adds that data to Error counter when the sign
of latest Mcmd reverses against the sign of the former Mcmd except Mcmd = 0.
This is why this function works at the right point in case of the following command,.
-1, 0, -1, -1, -1, 0, -1, -1 , -1, 0, 1, 1, 0, 0, 1, 0
