GD300-16 standard control board includes interface, can order the separated BACnet communication card, support 10M/100M, no need eds configuration file, refer to the attachmetn file.
The basic information of elevator are required to be collected, such as speed, load, number of floors, traction machine parameters, holding brake parameters, door motor controller parameters, etc., as shown in the annex.
1. Conventional scheme (applicable to 90% synchronous motors on site)
When the elevator starts (zero speed), the motor vibrates. Please reduce P4.17 and increase P4.18 appropriately;
When the elevator starts (zero speed), the motor moves to the heavy side (elevator running backward), please increase P4.17 appropriately and reduce P4.18; if the motor produces slight vibration or noise at this time, P4.21 current compensation coefficient can be appropriately increased to eliminate motor vibration and noise.
If the conventional scheme can not solve the starting reverse slip problem of synchronous motor on site, the following scheme can be tried:
2. Scheme 1: set P4.19 = 20 and P4.20 = 0.5. If the starting reverse slip is improved, the parameter of P4.19 can be increased gradually, and the value of P4.20 is 0.5, which remains unchanged until the start-up does not reverse. If P4.19 = 20, P4.20 = 0.5 is set and abnormal noise or vibration is generated during motor operation, please restore P4.19 and P4.20 to factory values and save parameters.
3. Scheme 2: add F0.17 parameter, add + 2 on F0.17 original parameter, P4.24 = 2, and appropriately reduce P4.25 parameter (- 5 / time, generally set to 35), until maintenance operation, elevator start-up moment does not reverse slip, and save parameters.
No.26 fault means the system does not output the test request (POU) of opening door in advance or creeping leveling or door lock short circuit connection, but receives feedback signal (POF)
The intelligent machine does not enable the function of opening door in advance or creeping leveling or door lock short-circuit test function, but there may be wiring problems on the EC-UCM circuit. The intelligent machine detects the action of POF signal and checks the POF signal circuit.
No.25 fault means the system outputs the test request (POU) of opening door in advance or creeping flat floor or door lock short circuit, but no feedback signal (POF) is received
The intelligent machine has enabled the function of opening door in advance or creeping leveling or door lock short-circuit test function, but it may be that there is no wiring on the EC-UCM or there is a problem in the circuit, and the POF signal action is not detected in the intelligent machine. Check the POF signal circuit.
No.78 fault means when the elevator runs to the end station, the system does not detect the corresponding deceleration switch action
1. After shaft self-learning, the position of deceleration switch has been moved artificially, so it is suggested to conduct shaft self-learning again;
2. It's due to serious slipping of wire rope, suggest that the acceleration and deceleration parameters should be set a little lower to try the operation again, or the parameter P0.02 (maximum speed of the elevator) can also be set a little lower;
3. It can set F0.21 (leveling operation scheme) = 100, save parameters, and power on the all-in-one machine. Enable the scheme of end crawl leveling.
No.39 fault means abnormal height of elevator (serious slipping of wire rope). The elevator is not located on the ground floor and the top floor, but the height data has been below or exceeded the limit value.
1. The guide shoe at the car side or counterweight side is too tight;
2. It is suggested that the acceleration and deceleration parameters should be set a little lower to try the operation again, or the parameter P0.02 (maximum speed of the elevator) can also be set a little lower;
3. It can set F0.21 (leveling operation scheme) = 100, save parameters, and power on the all-in-one machine. Enable the scheme of end crawl leveling.
1. At CLOSE operation, the elevator door has crashes. Adjust the operation curves, reduce CLOSE speed, P19.06 and P19.08.
2. At CLOSE operation, the elevator door closes and then open: CLOSE obstruction misjudgment, increase time and judgment coefficient (torque obstruction: P19.15, P19.16; slip obstruction: P19.20, P19.21, P19.22, P19.23; current obstruction: P19.24, P19.25, P19.26, P19.27, P19.28)
3. The elevator door cannot open or close smoothly: the operation curves are set improperly. OPEN stuck: adjust P18.00, P18.02, P18.04, P18.06, P18.08. CLOSE stuck: adjust P19.00, P19.02, P19.04, P19.06, P19.08. Set speed continuously, neither too high nor too low.
4. There is gap after CLOSE arrival: increase P19.14 and arrival hold torque.
