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

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).

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".

–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.

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.
