5.1.2 Smoothing

A filter can be applied in the SERVOPACK to a constant-frequency reference pulse. Use the
following parameter to set the type of filter to be applied.

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

Averaging Time for Average Movement Filter

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).

This function does not affect the travel distance (i.e., the number of pulses).
