Parameter Details
Explanation of Set Values
Set damping frequency 1 to suppress vibration at the end of the load in damping control.
Measure the frequency of vibration at the end of the load and make the setting in units of 0.1 Hz.
The range of frequency setting is 1.0 to 200.0 Hz. The function is disabled if the setting is 0 to 0.9
Hz.
Refer to "6-1 Damping Control" (P.6-1) for more information on settings.
First set the Damping Frequency 1 (Pn214). Then reduce the setting if torque saturation occurs or
increase the setting to increase operation speed. Normally, use a setting of 0.
Set value is restricted in the following manner.
Upper limit: Corresponding damping frequency
Lower limit: Damping frequency + damping filter setting ≥ 100
Refer to "6-1 Damping Control" (P.6-1) for more information on settings.
Set Damping Frequency 2 to suppress vibration at the end of the load in damping control.
Measure the frequency of vibration at the end of the load and make the setting in units of 0.1 Hz.
The range of frequency setting is 1.0 to 200.0 Hz. The function is disabled if the setting is 0 to 0.9
Hz.
Refer to "6-1 Damping Control" (P.6-1) for more information on settings.
First set the Damping Frequency 2 (Pn216). Then reduce the setting if torque saturation occurs
or increase the setting to increase operation speed. Normally, use a setting of 0.
Set value is restricted in the following manner.
Upper limit: Corresponding damping frequency
Lower limit: Damping frequency + damping filter setting ≥ 100
