FF Vibration Suppressor Frequency 1
[SUPFRQ1]
Setting range
Unit
Standard value
5 to 500
Hz
500
■
Sets the frequency of the machine vibration to be suppressed by FF vibration suppressor
function.
◆
Change this while the motor is OFF.
◆
Setting value can be input by 1Hz; inside the driver, the units listed below are used.

FF Vibration Suppressor Level Selection
[SUPLV]
Setting range
Unit
Standard value
00 to 03
-
00
■
Sets FF vibration suppressor control effect level.
◆
Change while motor is OFF.
◆
The smaller the value, the greater the effect will be.
◆
FF vibration suppressor frequency switching function does not affect this.

Velocity Command Notch Filter
[VCNFIL]
Setting range
Unit
Standard value
50 to 1000
Hz
1000
■
Notch filter to eliminate frequency element arbitrarily set from velocity command.
Sets the resonant frequency.
◆
When sympathetic vibration occurs in velocity control system, the gain is raised
by setting the resonance frequency.
◆
Setting value varies depending on the setting of the system parameter ID00 Control
Cycle.
Setting value can be input by 1[Hz]; inside the driver,
the units listed below are applied.
