During the rigid tapping, the time constant of linear acceleration or deceleration of the spindle
and the tapping axis is the time (parameter NO.5241) of the spindle maximum speed when the
spindle reaches the rigid tapping. The actual time is the ratio between the specified spindle speed
and the maximum speed multiplies by the parameter.

Set the time constant of linear acceleration or deceleration of the spindle and the tapping axis
during the rigid tapping run-out. The parameter is valid only when parameter TDR (NO.5201 BIT2) is
set as 1.

NO.5461 is 5
Set control axis number of rotary axis to execute polar interpolation.
Note:In the polar coordinate interpolation mode, the more closely the tool is near to the work piece center,
the bigger the speed vector of the rotary axis is. If the center part exceeds the maximum cutting
speed (parameter NO.5462), the servo (NO.411) alarms. Auto feedrate override and auto feedrate
limit function auto controls the feedrate, then, the speed vector of the rotary axis doesn’t exceed
the maximum cutting feedrate.
