Live Tool Control With Servo Motor
Acceleration/deceleration after interpolation
Unlike conventional rigid tapping, rigid tapping with servo motor enables
the application of bell-shaped acceleration/deceleration or linear
acceleration/deceleration of constant acceleration/deceleration time type.
When bit 0 (SRBx) of parameter No. 11001 is set to 0, linear
acceleration/deceleration of constant acceleration time type can be applied.
When the parameter is set to 1, bell-shaped acceleration/deceleration of
constant acceleration time type can be applied.
Set a time constant for the live tool axis of each gear in parameters
(Nos. 11060 to 11063).
When bit 2 (TDR) of parameter No. 5201 is set to 1, time constants for
cutting and extraction can be set in separate parameters
(Nos. 11065 to 11068).
Set these parameters with a live tool axis in rigid tapping.
The acceleration/deceleration type and the time constant of the drilling axis
become the same as the live tool axis set axis in rigid tapping.
The setting of a time constant differs from normal rigid
Example) Suppose that the parameters are set as follows: time constant
TC = 800msec and maximum spindle speed S = 4000 min
