2: Enabled (Manual threshold setting)
3: Threshold reset
When "2" is set to this digit, if the friction torque exceeds the set threshold, [AL. F7.2 Friction failure prediction
warning] will occur.
When the threshold is reset by setting "3" to this digit, "1" will be automatically set after the reset.
This digit is available with servo amplifier with software version A3 or later. 0h

parameter _ _ _ x Friction failure prediction - Threshold multiplication
Set a multiplication for calculating the threshold used in the friction failure prediction function. Setting a small
threshold multiplication for friction failure prediction will decrease the threshold used for friction failure
prediction. Thus, this will enable the prediction of a failure at an early stage, but will increase the possibility of
erroneously detecting a failure.
When "0" is set to this digit, the multiplication will be the same as when "5" is set.
This digit is available with servo amplifier with software version A3 or later. 0h
_ _ x _ Vibration failure prediction - Threshold multiplication
Set a multiplication for calculating the threshold used in the vibration failure prediction function. Setting a
small threshold multiplication for vibration failure prediction will decrease the threshold used for vibration
failure prediction. Thus, this will enable the prediction of a failure at an early stage, but will increase the
possibility of erroneously detecting a failure.
When "0" is set to this digit, the multiplication will be the same as when "5" is set.
This digit is available with servo amplifier with software version A3 or later. 0h
_ x _ _ Friction failure prediction - Dynamic friction selection
Select a dynamic friction setting used for friction failure prediction.
0: Automatic setting
1: Dynamic friction at forward rotation torque (at rated speed)
2: Dynamic friction at reverse rotation torque (at rated speed)
3: Absolute value average at forward rotation/reverse rotation torque
When "0" is set to this digit, any of "1" to "3" is set depending on the operation pattern.
This digit is available with servo amplifier with software version A3 or later. 0h
