Smoothing
The smoothing function applies a filter inside the servo amplifier to a constant-fre-
quency reference input so that acceleration and deceleration can be as constant as
possible. To use this function, set the following parameters.
Use the following parameter to set the type of filter to be applied.
Parameter
Position Reference Filter Selec-
Pn207.0
tion
Either an acceleration/deceleration or average movement filter can be selected.
The time constant and time for these filters are set in the following parameters.
Time constant for Acceleration/Deceleration Filter:
Parameter
Position Reference Accel/Decel
Pn204
Time Constant
Averaging time for Average Movement Filter:
Parameter
Position Reference Movement
Pn208
Averaging Time
This function provides smooth motor operating in the following cases:
•
When the host device which outputs references cannot perform acceleration/
deceleration processing.
•
When the reference pulse frequency is too low.
•
When the reference electronic gear ratio is too high (i.e., 10 × or more).
