Precautions for Correct Use
Stop operation before changing the parameters or switching with DFSEL.
Damping control may not function properly or the effect may not be apparent under the following
conditions.
Parameter
number
Parameter name Explanation Reference
Pn001
Control Mode
Selection
Set to the Position Control Mode or Fully-closed Control
Mode.
0: Position control
3: First control mode for position/speed control
4: First control mode for position/torque control
6: Fully-closed control

Pn213
Damping Filter
Selection
Select the damping filter switching mode according to the
condition of the unit.
0: Damping filter 1 or 2 enabled
1: Switching by external input (DFSEL1)
2: Switching by external input (DFSEL1, DFSEL2)
3: Switching with command direction
P.8-21
Pn214
Damping
Frequency 1
Set damping frequency 1 to suppress vibration at the end of
the load in damping control.
If the damping control function is not used, set 0.
P.8-22
Pn215
Damping Filter 1
Setting
When the Damping Frequency 1 (Pn214) is set, reduce the
setting if torque saturation occurs or increase the setting to
increase operation speed. Normally 0 is set.
If the damping filter 1 is disabled, this parameter is also
disabled.
P.8-22

Item Conditions under which the effect of damping control is inhibited
Control mode - Speed Control Mode or Torque Control Mode
Load condition
- If forces other than position commands, such as external forces, cause vibration.
- If the damping frequency is outside the range of 1 to 200 Hz.
- If the ratio of the resonance frequency to anti-resonance frequency is large.
