Frequency feedback signal attenuation of inverter

Based on your description, the frequency feedback signal from the inverter has experienced attenuation during transmission. There are several possible reasons for this: 1. Cable issues: The transmission lines may be damaged, resulting in high losses that cause signal attenuation. You need to check and replace the cables that may be faulty. 2. Resistance issue: If the resistance of the connection wires is too high, it will cause the current signal to attenuate during transmission. In this case, the circuit needs to be adjusted to reduce the resistance. 3. Interference issue: Strong electromagnetic interference can also cause signal attenuation. This requires checking whether there are strong electromagnetic sources nearby affecting the device. 4. Issues with the inverter or DCS side: There may be faults on the inverter or DCS side, preventing it from properly reading and processing the input signals. It is necessary to check and refer to the device’s user manual to determine whether such a problem exists. The corresponding solutions include cable replacement, circuit adjustment, elimination of interference sources, and repair or replacement of the equipment. When solving problems, it is recommended to first use the elimination method to identify the root cause, and then carry out the necessary repairs. You can also consult the equipment manufacturer or professional repair services to ensure that the equipment is operated correctly and safely. .

Did you measure it in parallel or in series? Either the error detection circuit is faulty. There’s also an unlikely possibility of other loads being connected in parallel in the circuit? First, ensure that the measurement is taken within the circuit, and that both ends are measuring the same wire.
