Fuji servo motor has self-tuning function, which can automatically adjust the device with low rigidity to meet most applications. The design life of key parts is up to 10 years, ensuring smooth operation of the equipment; the product model is from 50W to 3000W. Various needs;
First, Fuji servo motor performance
1. Control accuracy: The accuracy depends on its own photoelectric encoder. The more the scale of the encoder, the higher the accuracy. The Fuji servo motor has high control precision and is suitable for high-precision control.
2. Low-frequency characteristics: the operation is very stable, and vibration does not occur even at low speeds;
3. Moment frequency characteristics: constant torque output at rated speed, constant power output at rated speed;
4. Overload capability: strong overload capability;
5. Operation performance: AC servo drive system is closed-loop control. The drive can directly sample the motor encoder feedback signal. The internal position loop and speed loop are formed. Generally, the stepless motor over-step or overshoot phenomenon does not occur. More reliable performance;
6. Speed response performance: The AC servo system has better acceleration performance, usually only a few milliseconds, which can be used for control situations requiring fast start and stop.
Second, Fuji servo motor working mode:
The "switch" of Fuji PLC is used to control the start and stop of the servo controller. The start or stop of the servo controller is to start and stop the servo motor. The servo controller has higher control precision than the inverter.
Servo motors are generally used where high control accuracy is required (eg speed control, position control, torque control). Fuji servo motor comes with a photoelectric encoder. The rotation of the rotor drives the code wheel of the photoelectric encoder. The number of revolutions of the rotor directly affects the number of pulses sent by the encoder to the controller. The pulse causes the servo to rotate, and the DO output determines the servo direction. The pulse direction controls the servo direction, the forward pulse servo forward rotation, and the reverse pulse servo reverse rotation. Therefore, the Fuji servo motor combined servo controller can truly realize its precision control.
If you use the analog control servo, you can use positive and negative analog to perform forward and reverse control.
If communication control is used, the command is sent directly. Programmatically, you can directly enter the position JOG command to make it positive and negative.
