- 237 -
- Bottom dead point overshoot damp control
Bottom dead point overshoot damp control is enabled when the
chopping rate (command-specified rate overridden with a certain value,
not including a portion increased due to chopping compensation)
exceeds a value specified in parameter No. 1198. If bottom dead point
overshoot damp control is enabled, changing of the override value,
changing of the command-specified rate, and interlocking are enabled
only in the range from the top dead point to the bottom dead point.
Bottom dead point overshoot damp control is not performed if
parameter No. 1198 is 0.
- Mode switching during chopping
If the mode is changed during chopping, chopping does not stop. In
manual mode, the chopping axis cannot be moved manually. It can,
however, be moved manually by means of the manual interrupt.

Displacement between the tool and the upper dead point: L2, L4, L6
Displacement between the tool and the lower dead point: L1, L3, L5
@Compensation starts when:
|L3 - L2| < (parameter No.1881)
Compensation value:
L3*(parameter No.1196)
@When the following condition is satisfied, compensation is no longer applied,
@and the tool continues to move at its current feedrate:
|L6| < effective area setting @(parameter No.1827)
