What should I do if my inverter is not working?

Fault during communication via system bus. Check system bus connection. Encoder signal for master faulty. Hardware required for synchronous operation is missing. Check encoder wiring. Fit a new synchronous operation board. Drive has reached position of CW limit switch. Interruption in line between inverter and CW limit switch.

How to reduce negative current in flyback topology?

The effect is also harmful to Flyback topology. The effect depends on dV/dt, Crss/Ciss ratio, and driver strength to keep a high negative current. The solutions might be: to connect an external capacitance in parallel to Ciss, slow down dV/dt, or increase gate driver negative current capability (by adding an external PNP BJT for example).

How do I know if my inverter is bad?

Check connection between inverter and motor. Check cross section of motor cable and increase if necessary. Two or all output phases interrupted. Motor rated power too small in relation to inverter rated power. Check connection between inverter and motor. Check startup data and repeat startup procedure if necessary. Motor utilization too high.

What causes a systematic program error in an inverter?

Systematic program error caused by excessively frequent writing of CAN bus interface of an inverter. Reduce write accesses to inverter concerned in user program. Code 3: CAN controller overflow. CAN controller malfunction. Inform SEW Service if fault cannot be reset or if it occurs frequently. Code 4: CAN controller error.

How does Miller capacitance affect flyback topology?

2. Miller capacitance may cause uncontrollable parasitic switching, leading to a cross-conduction failure in half-bridge topology. The effect is also harmful to Flyback topology. The effect depends on dV/dt, Crss/Ciss ratio, and driver strength to keep a high negative current.
