14.30.2 Function Enabling Conditions

To use this function, it is necessary to satisfy the [Condition 1] and [Condition 2] as shown below.
[Condition 1]: Parameter conditions which enable this function for the ON/OFF of the command mode and high-accuracy
control mode.
[Condition 2]: Parameter conditions which are required to calculate the optimum acceleration/deceleration time constant from
the estimated inertia ratio.
This function is invalid for the axis which does not satisfy both [Condition1] and [Condition 2].
[Condition 1]
The following conditions have to be satisfied according to the ON/OFF of the target command mode and high-accuracy
control mode.
Command High-accuracy
mode control mode
G0 (Positioning) OFF
ON
G1 (Cutting OFF
feed)
ON
[Condition 2]
The following parameters have to satisfy the valid conditions
Parameter
#2237 JL (Load inertia scale)
#2400 RTJX (Real-time tuning: maxi-
mum adaptive inertia ratio)
Enabling conditions
 "#2651 RT2G0 (RT2: Enable switching of G0 acce/dece time constant)" is set to "1"
 "#2652 RT2G1 (RT2: Enable switching of G1 acce/dece time constant)" is set to "1"
 "#1427 RT2AftG1 (Enable switching of acce/dece time constant after G1 interpola-
tion)" is set to "1"
 "#2652 RT2G1 (RT2: Enable switching of G1 acce/dece time constant)" is set to "1"
 Variable-acceleration pre-interpolation acceleration/deceleration is enabled
Enabling conditions
For rotary motor: 100 or over
For linear motor: Larger than the gross
mass of the moving sections under the
condition without a workpiece
Set the value larger than #2237
775
Method of setting
Set load inertia ratio (gross mass of the mov-
ing sections)under the condition without a
workpiece.
Set estimated max inertia ratio (gross mass of
the moving sections).
