Compared with the U series servo, the W series servo positioning driver provides a high-frequency response of 400Hz (250Hz for the U series) and the highest rotational speed of 5000rpm (4500rpm for the U series)
Characteristics of servo positioning driver
1. A servo with positioning function can form a positioning system more simply
2. Compared with the U series servo, the W series provides a high-frequency response of 400Hz (250Hz for the U series) and the highest speed of 5000rpm (4500rpm for the U series)
3. All drive parameter settings and monitoring can be completed through panel operations
4. The motor complies with IP67 (waterproof) specifications
5. Online automatic adjustment
6. Provide 12 different control modes to adapt to different application scenarios
Settings
1. Set the internal torque limit value of the servo motor;
2. The set value is the percentage of rated torque;
3. At any time, this restriction effectively locates the completion range;
4. Set the pulse range for positioning completion under the position control mode;
5. This parameter provides the basis for the driver to determine whether the positioning has been completed under the position control mode. When the remaining number of pulses in the position deviation counter is less than or equal to the set value of this parameter, the driver considers the positioning to be completed and the position switch signal is ON, otherwise it is OFF;
6. When in position control mode, output position positioning completion signal and acceleration/deceleration time constant;
7. The set value represents the acceleration time of the motor from 0 to 2000r/min or the deceleration time from 2000 to 0r/min;
8. The acceleration and deceleration characteristics are a linear range of arrival speeds;
9. Set the arrival speed;
10. In non position control mode, if the motor speed exceeds the set value, the speed reaches the switch signal ON, otherwise it is OFF;
11. Under position control mode, this parameter is not required;
12. It is independent of the direction of rotation.
Precautions for servo positioning driver:
1. The correct shielding grounding point is at the reference potential point inside the circuit, which depends on whether the noise source and receiver are both grounded or floating.
2. Ensure that the shielding layer is grounded at the same point so that ground current does not flow through the shielding layer.
3. Avoid the ground circuit generated by multiple connection methods to the ground, which is easily affected by noise and generates current at different reference points.
4. Without isolation between the AC power supply and the driver DC bus, non isolated ports or signals of the DC bus cannot be connected to the ground, which may cause equipment damage and personnel injury.
5. Avoid connecting the servo drive to an external power source, as it will directly affect the operation of the controller and drive.
6. The common voltage for communication is not connected to the ground, and there may be high voltage between the DC bus and the ground. Direct grounding is prohibited.
7. In a servo system, the common ground and the earth must be connected at the signal end.
8. In order to maintain a constant command reference voltage, the signal ground of the servo driver needs to be connected to the signal ground of the controller.
In many cases, due to the high current and voltage of servo drives, such as some servo drives with a maximum output current of 8A and a voltage of 325V, and the lack of aluminum alloy casing for magnetic shielding, it causes interference in highly sensitive receiver systems
Disturbance, which makes it unable to work and interferes with the power supply, especially at high frequencies, may cause the microcontroller and upper computer of the control system to be unable to communicate normally, making it difficult to use normally. Therefore, the interference problem must be solved.
