Function
Sets the time required to deem that real-time auto tuning
load characteristics estimate has converged when
deterioration diagnosis warning function is activated
(Pr6.97 bit 1 = 1).
When the set value is 0, it will be set automatically inside
the driver in accordance with Pr6.31 (real-time auto
tuning convergence velocity).
* When Pr6.31 (real-time auto tuning convergence
velocity) = 0, the deterioration diagnosis warning
judgment for load characteristics estimate will be invalid.
Sets the upper and lower limit values for inertia ratio
estimate in deterioration diagnosis judgment when
deterioration diagnosis warning is valid (Pr6.97 bit 1 = 1)
and load characteristics estimate convergence has been
completed.
* The set resolution shall be in units of 0.2%.
Sets the upper and lower limit values for unbalanced
load estimate in deterioration diagnosis judgment when
deterioration diagnosis warning is valid (Pr6.97 bit 1 = 1)
and load characteristics estimate convergence has been
completed.
* The set resolution shall be in units of 0.2%.
Sets the upper and lower limit values for dynamic friction
estimate in deterioration diagnosis judgment when
deterioration diagnosis warning is valid (Pr6.97 bit 1 = 1)
and load characteristics estimate convergence has been
completed.
* The set resolution shall be in units of 0.2%.
Sets the upper and lower limit values for viscous friction
coefficient estimate in deterioration diagnosis judgment when
deterioration diagnosis warning is valid (Pr6.97 bit 1 = 1) and
load characteristics estimate convergence has been
completed.
* The set resolution shall be in units of 0.2%.
