Filter Time
Constant 2
(RT) 2 Sets the speed detection filter when using gain 2 switching.
Same function as Pn013. Normally, use a setting of 0.
When Instantaneous Speed Observer Setting (Pn027) is enabled,
this parameter will be disabled. 0 --- 0 to 5 Online

Pn01D Notch Filter
1 Fre-
quency 2 Sets the notch frequency of notch filter 1 for resonance suppres-
sion.
This filter must be matched with the resonance frequency of the
load. 1500 Hz 100 to 1500 Online
100 to
1499 Filter enabled
1500 Filter disabled
Pn01E Notch Filter
1 Width 2 Selects the notch width of notch filter 1 for resonance suppression.
Normally, use a setting of 2. 2 --- 2 Online
Pn01F Reserved --- Do not change. 0 --- --- ---
Pn020 Inertia Ratio
(RT) 2 Sets the load inertia as a percentage of the Servomotor rotor iner-
tia.
Setting [%] = (Load inertia / Rotor inertia)
×

The inertia ratio estimated during realtime autotuning is stored in
the EEPROM every 30 minutes.

Pn021 Realtime
Autotuning
Mode
Selection 2 Sets the operating mode for realtime autotuning.
A setting of 3 or 6 will provide faster response to changes in inertia
during operation. Operation, however, may be unstable depending
on the operating pattern.
Normally, use a setting of 1 or 4.
Set to 4 to 6 when the Servomotor is used as a vertical axis.
Gain switching is enabled at set values 1 to 6.
Use a setting of 7 if operation changes caused by gain switching
are a problem. 0 --- 0 to 7 Online
Pn022 Realtime
Autotuning
Machine
Rigidity
Selection 2 Sets the machine rigidity for realtime autotuning.
Increasing this value increases the responsiveness.
If the value is changed suddenly by a large amount, the gain will
change rapidly, subjecting the machine to shock.
Always start by making small changes in the value, and gradually
increase the value while monitoring machine operation.
Cannot be set to 0 when using the Parameter Unit. 2 --- 0 to F Online
