S curve speed command acceleration and
deceleration time setting.
Sn208
Set
Sn205
=
3 to enable this function.
In the period of Accel. and Decel. , drastic speed
changing might cause vibration of machine. S curve
speed command Accel. and Decel. time setting has
the effect to smooth Accel. and Decel. curve.

Speed loop Gain 1
Sn211
Speed loop gain has a direct effect on the frequency
response bandwidth of the Speed-control loop.
Without causing vibration or noise Speed-loop-gain
can be increased to obtain a faster speed response.
If
Cn025 (load Inertia ratio)
is set correctly, the
speed-loop-bandwidth will equal to speed-loop-gain.

Speed-loop Integral time 1
Sn212
Speed loop integral element can eliminate the steady
speed error and quick response for speed variations.
Decreasing Integral time can improve system rigidity.
The formula below shows the relationship between
Integral time and Speed loop Gain.
