*1 If the damping control function is not used, set the damping frequency to a value between 0 and 0.9 Hz.
*2 This object is also disabled when the damping frequency is disabled. In addition, the upper limit of the set
value is restricted to the corresponding damping frequency or the value of (2000 minus damping frequency),
whichever is the smaller.
Precautions for Correct UsePrecautions for Correct Use
• The damping frequency and damping filter settings are switched when the position command
value per 0.250 ms changes from 0 to a value other than 0 while the positioning completed
output is ON.
In particular, if the damping frequency is changed to a larger value or disabled and a large
Position window is set, the motor may move suddenly immediately after switching.
This occurs due to the pulses accumulated in the filter at the time of switching, which are
distributed rapidly after switching to restore the normal position.
Be careful as the motor may temporarily operate faster than the expected command speed.
• There is a delay from the time when the damping frequency and damping filter settings are
changed until the new values are applied in internal calculations. If the filter switch wait time
expires during this delay, the change may be placed on hold.
