3.4.3 Servo Parameter Adjustment Procedure for Achieving High
Speed and High Precision
(1) Overview
This section describes the procedure for determining the digital servo
parameters used for advanced preview control, high-precision contour
control, and AI nano-contour control, and the parameters for CNC
acceleration and deceleration based on a feedrate difference. This
section assumes that the servo adjustment software SD.EXE (of a
version of November 1997 and later) is used.
(2) Standard settings
Before staring an actual adjustment, set the default parameters
according to Table 3.4.3 (a). With the servo software series (Series
9080, 9090, and 90A0) that allows the application of fine
acceleration/deceleration, fine acceleration/deceleration can be used
instead of linear acceleration/deceleration after interpolation.
However, fine acceleration/deceleration is disabled during high-
precision contour control, AI contour control, and AI nano-contour
control. So, be sure to set the parameter for acceleration/deceleration
after interpolation on the CNC side during batch transfer (such as
during RISC use).
