Automatic notch filter
To enable the adaptive notch filter function, just set "P1A Group - Advanced Adjustment - Vibration Suppression Mode Selection" of 1 or 2 in the backend software; SV3 servo supports up to 4 adaptive notch filters. When the system has 5 or more resonance points, it shall manually set the notch filters. It supports up to 4 different notch frequency settings.
Under the following conditions, it might be impossible to perform normal automatic vibration suppression. In this situation, please perform manual vibration suppression.
| Factors of adaptive vibration suppression | |
| Resonance characteristics |
When resonance frequency is lower than the velocity response frequency When 3 or more resonance points exist When vibration amplitude is small, or control gain is low, and the impact on motor speed is nonsignificant |
| Mechanical properties | Nonlinear factors such as excessive tooth clearance in operation or excessive backlash in forward/negative rotation, e.g., misaligned gear installation in gear transmission mechanismVibration components randomly appear and last for a short period |
| Movement conditions |
Rapid acceleration/deceleration, when acceleration is greater than 30000rpm/s When the servo operates in torque mode |
