Comfort Adjustment Of Professional Elevator Manufacturer

2019-08-22

If the comfort and leveling accuracy of the elevator is not good enough, the mechanical condition of the system should be checked first, such as the clearance of the guide shoe, the lubrication of the guide shoe, whether the tightness of the wire rope is even or not, whether the position of the rope end clamp is suitable, etc. , all of these can affect the comfort of the elevator. After the mechanical part has been checked, the control part can be adjusted.


Because the INVERTER is in accordance with a given starting and braking curve to control the operation of the motor, therefore, given the shape of the starting and braking curves, the speed of motor feedback controlled by the frequency converter to track the curves and the timing logic of the control signals sent by the main control unit to the frequency converter will directly affect the comfort of the elevator. Details are as follows:


Adjustment of starting and braking curve

                 igure 2-1 diagram of Operation Curve



The s-curve of the starting section is adjusted by the following three parameters

P 1: The increasing speed at the beginning of starting is the change rate of acceleration of the curve. The smaller the value, the slower the beginning of starting is and the smoother the feeling is.

B1: The acceleration at the start, which means the rate of change of the speed of the curve, the smaller the value, the slower the acceleration at the start, the smoother the feeling.

P2: Acceleration Reduction during start-up. The smaller the value is, the slower the starting end is, and the smoother the feeling is.

The S curve of the brake section is adjusted by the following three parameters

P 3: increase and decrease speed at the beginning of braking: This means the change rate of deceleration of curve, the smaller the value, the slower the deceleration beginning, the more stable the feeling.

B 2: Deceleration Acceleration: The meaning is the curve speed change rate, the smaller the value, the slower the braking deceleration, the more stable the feeling.

P 4: The deceleration of the braking knot is the change rate of the curve deceleration. The smaller the value is, the slower the braking ending is, and the more stable the feeling is.


The above 6 parameters should be adjusted properly to obtain the running curve of the elevator under the premise of ensuring the running efficiency of the elevator.


Adjustment to curve tracking

The frequency converter must control the motor so that its feedback speed strictly follows the change of the given operating curve to achieve the desired comfort.

The frequency converter sets up the mathematical model according to the motor parameters input by the user, and controls the starting and braking operation of the motor according to the model. Therefore, the user must input the accurate motor parameters. Self-learning of motor parameters is recommended


The parameters of proportional gain C5-01 and integral gain C5-02 of the speed loop will also affect the tracing degree of the curve. In general, increasing the proportional gain will improve the dynamic response of the system and the tracking speed. However, excessive proportional gain will cause high-frequency vibration of the system and increase the noise of the motor. Increasing the integral will improve the ability of anti-disturbance and tracking, and improve the accuracy of level, but too much integral gain will make the system oscillate, which shows as overshoot of speed and wave-like jitter.


In general, the proportional gain is adjusted first to increase the value as much as possible without oscillation. Then adjust the integral gain, so that the system has both fast response characteristics and little overshoot.
