XMFA-9000 Intelligent Servo Control PID Regulator Function
1. Various analog or frequency inputs.
2. Multiple display of process quantity, set value, control quantity, valve position feedback quantity, etc.
3. The measured value and the given value can be added or subtracted.
4. Positive and negative action selection of servo control PID regulator .
5. The upper and lower limit output control ranges can be set separately.
6. The analog value of valve position feedback can be used to calibrate zero point and full scale.
7, 2 or 3 analog output: 0 ~ 10mA, 4 ~ 20mA.
Selection of 8 or 8 alarm control modes.
9. It has the braking function of motor forward and reverse control. Valve position feedback fault can be relay output.
10. The input switch SB function controls the setpoint transfer.
11. Built-in 41A triac controls the electric actuator directly.
12. The measurement input signal can be used for square root and small signal resection.
13. Automatic startup or manual startup position hold or manual startup preset. Valve position feedback disconnection automatically enters the manual state (ordering must be specified).
14. Intelligent sound and light alarm, intelligent timer or counter function with silence time can be realized.
15. PID parameter self-tuning or P parameter independent self-tuning. 8 groups of setting values and P, I, D parameters are stored and recalled.
16. Remote hand automatic status control. The remote control console hard hand operation; the control output of the remote switch control regulator is PID adjustment mode or the operation console hard hand operation state, two-way non-disturbance switching; the remote servo PID regulator control mode or the host computer direct control mode.
17. The direct control mode of the host computer automatically switches to its own PID adjustment control mode when the input signal fails; when the direct control mode of the host computer, the servo control PID regulator automatically tracks the input signal of the host computer.
18. RS485 asynchronous serial communication mode with multiple masters, single masters and no masters can be provided. Communication data verification complies with CRC-16 American data communication standard, high reliability cycle, bar code verification
