Parameters Details
 Set vibration frequency 3 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.
 Setting frequency is 1.0 to 200.0 Hz. The function will be disabled if the setting is 0 to 0.9 Hz.
 Refer to "6-1 Anti-vibration Control" (P.6-3) for more information on settings.
 First set the Vibration Frequency 3 (Pn218). 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 vibration frequency
Lower limit: Vibration frequency + vibration filter setting ≥ 100
Refer to "6-1 Anti-vibration Control" (P.6-3) for more information on settings.
 Set vibration frequency 4 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.
 Setting frequency is 1.0 to 200.0 Hz. The function will be disabled if the setting is 0 to 0.9 Hz.
 Refer to "6-1 Anti-vibration Control" (P.6-3) for more information on settings.
 First set the Vibration Frequency 4 (Pn220). 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 vibration frequency
Lower limit: Vibration frequency + vibration filter setting ≥ 100
Refer to "6-1 Anti-vibration Control" (P.6-3) for more information on settings.
 The position command filter time constant is the first-order lag filter inserted after the electronic
gear ratio for the command pulse input.
The position command filter time constant can be used for the following:
· If the command pulses change abruptly, the filter can be used to reduce the stepping
movement of the motor.
· The following are examples of when the command pulses can change abruptly:
The electronic gear ratio setting is high (10 times or higher).
The command pulse frequency is low.
