11-7-1 Objects Requiring Settings
Precautions for Correct Use
• Stop operation before changing the object settings.
• Damping control may not function properly or have no effect under the following conditions.

Damping Filter 1 Sets the damping filter 1. P. 9-19
01 1st Frequency Sets the damping frequency for the damping filter. P. 9-19
02 1st Damping Time
Coefficient
Sets the trade-off with torque required for the vibration sup-
pression time and damping.
Setting a small value shortens the time to suppress the vibra-
tion, however it is highly possible that torque saturation
occurs.

Item Conditions that interfere with the effect of damping control
Load condition • If forces other than position commands, such as external forces, cause vibration
• If the damping frequency is outside the range of 0.5 to 300 Hz
• If the ratio of the resonance frequency to anti-resonance frequency is large
