Introduction

EasySSS control is used in high speed and high accuracy modes. Improved speed and speed control is achieved with this function. Increases the smoothness of the workpiece surface.

Parameters

To activate this function, it is necessary to set parameter # 8090 to “1”. Standard values ​​of the parameters used below:

#8090 = 1 (Easy SSS control active)
#8091 = 1 (1 is standard value, to eliminate the effect of steps or errors, etc., set a large value. To enable sufficient deceleration, set a small value. If 0 is set standard value 1 will be applied)
#8092 = 1 (ClampCoeff. Standard value =1. Set the clamp speed at the curved section configured of fine segments.)
#8093 = 5 (StepLength, standard = 5 micrometers. Set the width of the step at which the speed is not to be decelerated. (Approximately the same as the CAM path difference [Tolerance].)
#8094 = Deceleration Wait Time, set the time to wait for deceleration when the speed FB does not drop to the clamp speed. (Setting: 0 to 100 ms)
#1571 = Selection of SSS control constant coefficient value (Setting 0/1)
