estimation speed
0–3 —
Set up the load characteristics estimation speed with the real time auto
tuning being valid. A higher setup value assures faster response to a
change in load characteristics but increases variations in disturbance
estimation. Result of estimation is saved to EEPROM every 30 minutes.

Description
0
No change
Stop estimation of load characteristics.
1
Almost constant
Response to changes in load
characteristics in every minute.
2
Slower change
Response to changes in load
characteristics in every second.
3
*
Faster change
Obtain best suitable estimation in
response to changes in load
characteristics.
* If the automatic oscillation detection is enabled by the support
software, the setup value 3 is used.

Enable/disable the load characteristics
estimation function.
Setup value=0: Disable

Inertia ratio update
*3
Set up update to be made based on result
of the load characteristics
estimation of
Pr 0.04 “Inertia ratio”.
Setup value=0: Use current setup.
Setup value=1: Update by the estimated
value.

Torque compensation
*4
Set up the update to be made according
to the results of load characteristics
estimation of Pr 6.07 “Torque command
additional value”, Pr 6.08 “positive
direction torque compensation value”
and Pr 6.09 “negative direction torque
compensation value”.
Note) CCW direction is positive.
Setup value=0: Use current setup
Setup value=1: Disable torque
compensation
Clear the parameters shown above to
zero.
Setting value = 2: Vertical axis mode
Update Pr 6.07. Zero clear Pr 6.08 and
Pr 6.09
Setting value = 3: Friction compensation
(low)
Update Pr 6.07. Set low compensation
to Pr 6.08 and Pr 6.09.
Setting value = 4: Friction compensation
(middle)
Set middle compensation to Pr 6.08 and
Pr.6.09.
Setting value = 5: Friction compensation
(high)
Set high compensation to Pr 6.08 and
Pr 6.09.
*1 If the load characteristics estimation is disabled, the current setup
cannot be changed even if the inertia ratio is updated according to
the estimated value. When the torque compensation is updated by
the estimated value, it is cleared to 0 (invalid).
*2 If the load characteristics estimation is abled, set Pr6.31 "Real-time
auto tuning presumption speed" besides 0(stop estimation).
