Arc clamp speed coefficient for SSS control
Specify the compensation coefficient to be used for adjusting a path error and clamp speed on an arc under
SSS control. This parameter is enabled during SSS control. Thus set this parameter if you wish to use differ-
ent compensation coefficients according to ON/OFF of SSS control (If you wish to adjust a path error and
clamp speed on an arc, use "#8023 CURVE COMP").
If the setting value is smaller, the theoretical path error will decrease, but the cycle time may be longer be-
cause the arc clamp speed will slow down.
Note that this parameter is enabled when "#8096 Deceleration coefficient for SSS control ON" is "1".
When "0" is set in this parameter, the standard value (100%) is applied.
---Setting range---
0 to 2000 (%)
Specify the time constant of filter that is used for smoothing the change of jerk when pre-interpolation accel-
eration/deceleration is performed in cutting feed.
This filter causes no path error, as the filter is applied to the total speed calculated before interpolation.
If you specify the jerk filter time constant, the time constants of each filter will be as follows:
* S-shape filter time constant
"#1568 SfiltG1" - "Jerk_filtG1"
* Jerk filter time constant
"Jerk_filtG1"
---Setting range---
0 to 50 (ms)
Specify the time constant of filter that is used for smoothing the change of jerk when pre-interpolation accel-
eration/deceleration is performed in cutting feed.
This filter causes no path error, as the filter is applied to the total speed calculated before interpolation.
If you specify the jerk filter time constant, the time constants of each filter will be as follows:
* S-shape filter time constant
"#1569 SfiltG0" - "Jerk_filtG0"
* Jerk filter time constant
"Jerk_filtG0"
---Setting range---
0 to 50 (ms)
Select how to calculate the deceleration speed for a corner between the blocks where the high-accuracy con-
trol is enabled.
0: Optimal corner deceleration
(calculate the deceleration speed using the acceleration tolerance common for all the axes determined
by G1bF and G1btL)
1: Per-axis acceleration tolerance control
(calculate the deceleration speed using acceleration tolerances of each axis determined by G1bFx and
G1btLx)
Select whether to enable variable-acceleration pre-interpolation acceleration/deceleration control while high-
accuracy control is ON.
0: Pre-interpolation acceleration/deceleration
(Apply the acceleration rate that is determined by G1bF and G1btL and is common for all the axes)
1: Variable-acceleration pre-interpolation acceleration/deceleration
(Apply the acceleration rate that is determined by G1bFx and G1btLx for each axis)
(Note) Variable-acceleration pre-interpolation acceleration/deceleration is a function available under SSS
control. To enable this function, set "#8090 SSS ON" to 1.
