Current FDBK sum DSP
The software detects that the three-phase output current vector sum is not 0 and exceeds the parameter INV IO LIMIT
(1) Check INV IO LIMIT;
(2) Check the insulation of the three-phase output U, V, W;
(3) Check the connection between VA/VB and XU2 board;
(4) Replace XU2 board or LEM board;
(5) Replace inverter
6. Overtemp Motor or inverter overheating
(1) Is the ambient temperature too high?
(2) Check whether the inverter fan is working?
(3) Check thermistor and related plug-ins;
(4) Replace XU2 board
7. Motor Overload Motor overload
(1) Check speed parameters and motor learning parameters;
(2) Check parameters DRIVE RATED
RMS, MTR OVL TMR, MTR OVL I FAC, INV I FASCALE;
(3) Check MCSS acceleration, jerk and balance coefficient parameters;
(4) Is the brake fully open?
(5) Motor connection;
(6) Balance coefficient;
(7) PVT and connection
Q1: How do I identify the correct replacement elevator PCB board?
To identify a replacement elevator PCB board, check the original part number, hardware revision, board markings, and elevator controller model. Clear photos of both sides of the PCB can help distinguish different versions.
Q2: Can elevator PCB boards with similar part numbers be interchangeable?
Not necessarily. Elevator PCB boards with similar part numbers may differ in hardware revisions, firmware, connector layouts, or communication protocols. Compatibility must be verified against the existing elevator system.
Q3: Does a replacement elevator PCB board require programming?
Some replacement PCB boards require firmware configuration, parameter settings, or system-specific programming. Others may already contain the required software. The correct procedure depends on the PCB model and its role in the elevator control system.
Q4: Can a faulty elevator PCB board be replaced without changing the complete control system?
In some cases, an individual PCB can be replaced if the replacement is compatible with the existing controller, firmware, wiring, and connected components. A qualified technician should confirm the fault before deciding on replacement.
Q5: What information should I provide when sourcing a replacement elevator PCB board?
Please provide the original PCB part number, hardware revision, elevator model, clear board photos, and required quantity. SULAB can help review these details and check available replacement options.
