Damping Control
When the machine end vibrates, damping removes the vibration frequency from the commands,
reducing vibration.

• Under the following conditions, damping control may not operate properly or may have no effect.
• The following conditions must be met to use damping control.
Conditions under which damping control operates
Control Mode
• The Position Control Mode must be used.
Pn02 = 0: Position control
Pn02 = 3: Control mode 1 for position/speed control
Pn02 = 4: Control mode 1 for position/torque control

Load
• If forces other than commands, such as external forces, cause vibration.
• If the ratio of the resonance frequency to anti-resonance frequency is large.
• If the vibration frequency is outside the range of 10.0 to 200.0 Hz.
