First, the wiring of the main circuit
1. The power supply should be connected to the R, S, and T terminals at the input end of the inverter, and must not be connected to the output terminal (U, V, W) of the inverter, otherwise the inverter will be damaged. After wiring, the fragmented wires must be cleaned, and the fragmented wires may cause abnormalities.
malfunctions and malfunctions, the drive must be kept clean at all times. etc. into the inverter.
2. Do not connect anything other than the recommended braking resistor option between terminals + and PR, or never short circuit.
3. Electromagnetic wave interference, the input/output (main circuit) of the inverter contains harmonic components, which may interfere with the communication equipment near the inverter. Therefore, the optional Radio Noise Filter FR-BIF or FRBSF01 or FR-BLF line noise filter is installed to minimize interference.
4. When wiring for long distances, due to the influence of the parasitic capacitor charging current of the wiring, the fast response current limit function will be reduced, and the instrument connected to the secondary side will malfunction and cause failure. Therefore, the maximum routing length should be less than the specified value. If the wiring length is exceeded, set Pr.156 to 1.
5. Do not install power capacitors, surge suppressors and radio noise filters on the output side of the inverter. Failure to do so will result in drive failure or damage to capacitors and surge suppressors.
6. In order to make the voltage drop within 2%, the appropriate type of wire should be used. When the wiring distance between the inverter and the motor is long, especially in the case of low-frequency output, the torque of the motor decreases due to the voltage drop of the main circuit cable.
7. After operation, the operation of changing the wiring must be cut off for more than 10min and the voltage must be checked with a multimeter. For some time after a power outage, there is still dangerous high voltage on the capacitor.

Yaskawa inverter - the selection of high-voltage inverter precautions
1 Disadvantages of choosing too high a voltage level
Choosing too high a voltage level results in too high an investment and a long payback period. With the increase of the voltage level, the insulation of the motor must be improved, so that the price of the motor increases. The increase of the voltage level increases the number of series connections of power semiconductor devices in the inverter, ...
