Servo-variateur AC
230 VAC, 0.05 - 5 kW | Sigma-3 Yaskawa Europe

Online vibration monitor automatically detects frequencies and sets notch filter frequency during operation.
Less deviation control improves machine follow-up accuracy.
Predictive control amends the command being executed for improved servo response.
Backlash compensation adds a value to the position reference in one direction.
Vibration suppression control minimizes vibration when the motor stops (servo-lock).
Automatic gain switching uses combinations of speed loop gain, speed control integral time constant, position loop gain and filter time constant for torque reference.
Model follow-up control effects high-speed positioning of low rigidity machines.
Torque reference filter suppresses vibration in the servo system caused by shaft resonance.
Speed observer control enables smooth motion at low speeds and short position settling time.
Proportional/integral speed loop and proportional control prevents motor overshoot during acceleration and deceleration.
Feed-forward compensation.
Zero clamp function uses a position loop to stop motor (servo-lock) below a preset speed command.
