Specifies the first damping frequency of damping control to
suppress vibration of an end of the load. Measure the
frequency of the vibration of the load end and specify in
increments of 0.1 [Hz].
The effective frequency setting range is 1.0 - 200.0 [Hz].

1 Switching of damping frequency and damping filter setup is performed during output of positioning

completion, and upon starting up command of changing command pulse (before positioning command filtering)
from “0” to a value other than “0” for an command pulse detection cycle (0.166 ms).

If damping frequency is particularly high or it is changed to be invalid, and a wide range of positioning com-

pletion has been specified, massive amount of residing pulses in the filter (an area found by integrating a value of
subtracting position command after filtering from position command before filtering with time) may be suddenly
released immediately after switching. Therefore, a sudden action of returning to a correct position may result in
temporary rotation of motor faster than originally instructed. Use caution.
