10 0 to 3000
A to C-frame:<63>*
D to F-frame:<32>*
1/s1st gain of
position loop
You can determine the response of the positional control system.
Higher the gain of position loop you set, faster the positioning time you
can obtain. Note that too high setup may cause oscillation.
11 1 to 3500
A to C-frame:<35>*
D to F-frame:<18>*
Hz1st gain of
velocity loop
You can determine the response of the velocity loop.
In order to increase the response of overall servo system by setting high
position loop gain, you need higher setup of this velocity loop gain as well.
However, too high setup may cause oscillation.
<Caution>
When the inertia ratio of Pr20 is set correctly, the setup unit of Pr11
becomes (Hz).
12 1 to 1000
A to C-frame:<16>*
D to F-frame:<31>*
ms1st time constant
of velocity loop
integration
You can set up the integration time constant of velocity loop.
Smaller the setup, faster you can dog-in deviation at stall to 0.
The integration will be maintained by setting to "999".
The integration effect will be lost by setting to "1000".
13 0 to 5
<0>*
–1st filter of
speed detection
You can set up the time constant of the low pass filter (LPF) after the
speed detection, in 6 steps.
Higher the setup, larger the time constant you can obtain so that you can
decrease the motor noise, however, response becomes slow. Use with a
default value of 0 in normal operation.
15 –2000
to 2000
<300>*
0.1%Velocity feed
forward
You can set up the velocity feed forward volume at position control.
Higher the setup, smaller positional deviation and better response you can
obtain, however this might cause an overshoot.
16 0 to 6400
<50>*
0.01msTime constant of
feed forward filter
You can set up the time constant of 1st delay filter inserted in velocity feed
forward portion.
You might expect to improve the overshoot or noise caused by larger
setup of above velocity feed forward.
14 0 to 2500
A to C-frame:<65>*
D to F-frame:<126>*
0.01ms1st time constant of
torque filter
You can set up the time constant of the 1st delay filter inserted in the
torque command portion. You might expect suppression of oscillation
caused by distortion resonance.

Setup of front
panel lock
You can limit the operation of the front panel to the
monitor mode only.
You can prevent such a misoperation as unexpec-
ted parameter change.
<Note>
You can still change parameters via communication even though this setup is 1.
To return this parameter to 0, use the console or the "PANATERM

".

•For parameters which No. have a suffix of "*", changed contents will be validated when you turn on the
control power.
• Parameters which default values have a suffix of "*" will be automatically set up during real time auto-gain
tuning. When you change manually, invalidate the real-time auto-gain tuning first then set, referring to
P.239, "Release of Automatic Gain Adjusting Function" of Adjustment.
