amount to avoid excess movement due to higher speed and stopping inertia.
G00 mode, moves in theoppositedirection as homing,a compensation amount of A-0.5*(A-B) =
0.5*(A+B) is applied to overcome backlash and inertia.
P.s. Notice Pr1241~ is not the compensation value, but to be calculated by Pr1261 and the excess
movement caused by inertia. E.g. Pr1261=10, excess movement =2, then Pr1241 =6.
Compatibility
From version 10.112.0 to 10.116.23, the relation between backlash compensation and speed is
exponential. High speed (G00) backlash is Pr1241~, low speed (F10) backlash is Pr1261~, and
exponential conversion constant is Pr1281~.
In version 10.112.45 and earlier, Pr1261~ and Pr1281~ must be set 0 for Linear Way Compensation
Mechanism so controller only uses Pr1241~ to compensate.
No Descriptions Range Unit Default Effective
1241~1260 Axial G00 backlash [-999999~ 999999] BLU 0 Reset
When Linear Way Compensation Mechanism is enabled, Pr1241~ is used to compensate backlash of Rapid
Traverse, Cutting or Jog movements.
When Box Way Compensation Mechanism is enabled, the backlash compensation is calculated base on
Pr1241~, Pr1261~, and movement direction. Refer ro Pr1221~ for detail.
Compatibility
From version 10.112.0 to 10.116.23, this parameter is the amount of backlash compensation when
axis movement reverts under high speed (G00).
No Descriptions Range Unit Default Effective
1261~1280 Axial G01 backlash [-999999~ 999999] BLU 0 Reset
When Box Way Compensation Mechanism is enabled, this parameter is the amount of movement to
compensate backlash when axis movement reverts under cutting mode (G01/G02/G03).
Conmpatibility
From version 10.112.0 to 10.116.23, this parameter is the amount of backlash compensation when
axis movement reverts at low speed (F10).
No Descriptions Range Unit Default Effective
1281~1300 Backlash critical speed [0~3000] mm/min 0 reset
The backlash and the speed is a exponential relation, this parameter decides backlash converge speed. If the
value is bigger, the converge speed is faster.
When Pr1281~ are zero, controller will still follow default value 800 to process compensation amount
estimation. But other values will not.
Compatibility:
Valid from version 10.112.0.
In version 10.116.24 and later, this parameter no longer affects backlash compensation.
