#7 #6 #5 #4 #3 #2 #1 #0
1602 G8S
[Data type] Bit
#5 G8S Look-ahead feed forward for serial spindle is:
0: Disabled
1: Enabled
Set this parameter to “1” when Cs axis is used during AI contour control mode, AI Nano
contour control mode, AI high precision contour control mode or AI Nano high precision
contour control mode.
In case of AI contour control or AI Nano contour control
#7 #6 #5 #4 #3 #2 #1 #0
7052 NMI
[Data type] Bit axis
# 0 NMI Set this parameter to “0” when Cs axis is used during AI contour control mode or AI Nano
contour control mode.
NOTE
1. If the CNC software or Spindle software is not support this feature,
Cs axis is interpolated in different interval from servo axes. So the
contouring path may have a deviation from commanded path.
2. When this parameter is set, power must be turned off before operation
is continued.
