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, it is necessary to clean the trivial wire head, which may cause abnormalities, malfunctions and problems, and it is necessary to keep the inverter clean at all times. When punching holes in the console, be careful not to let debris powders and the like enter 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 disturbance, the input/output (main circuit) of the inverter includes harmonic components, which may disturb the communication equipment adjacent to the inverter. As a result, the installation can be equipped with an optional radio noise filter FR-BIF or FRBSF01 or FR-BLF line noise filter to minimize disturbances.
4. When wiring at long intervals, due to the influence of the parasitic capacitor charging current of the wiring, the fast response current constraint function will be reduced, and the instrument connected to the secondary side will malfunction and cause problems. As a result, the maximum wiring length is less than the specified value. If the wiring length is exceeded, Pr. 156 should be set 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 malfunction of the drive or damage to the capacitance and surge suppressor.
6. In order to make the voltage drop within 2%, the appropriate type of wire should be used. If the wiring interval between the inverter and the motor is long, especially in the case of low-frequency output, the torque of the motor will drop due to the voltage drop of the main circuit cable.
7. After operation, it is necessary to change the operation of wiring, and it is necessary to check the voltage with a multimeter after the power supply is blocked for more than 10min. For some time after a power outage, there is still a risk of high voltage on the capacitor.
