1. Load type and inverter selection: Choosing the right inverter is crucial for proper operation. It’s important to understand the load characteristics, environmental conditions, and inverter specifications before installation. Different loads have different requirements. A: Fans and pumps are among the most common types of loads. These applications typically require the simplest inverter setups, as long as the inverter capacity matches the motor’s rating. However, for more demanding applications like air compressors, deep water pumps, sediment pumps, or high-speed water fountains, a higher inverter capacity may be necessary. B: Crane-type loads involve heavy starting torque and sudden mechanical shocks. In such cases, the inverter must have sufficient margin to handle these stresses. Additionally, when the load is lowered under weight, energy can be fed back into the system, so it's recommended to use a braking unit or a common bus solution to manage this. C: Loads that vary in intensity, such as those found in rolling mills, crushers, or mixers, require careful consideration. The inverter should be sized based on the maximum load rather than the average, to ensure reliable performance during peak demand. D: Large inertia loads, like centrifuges, punching machines, or cement plant kilns, pose unique challenges. These systems have significant rotational inertia, which can cause oscillation during startup and generate feedback energy during deceleration. To mitigate these issues, a slightly larger inverter is often used to speed up the start-up process and reduce oscillations. A braking unit is also recommended to handle the energy feedback effectively. 2. For long-term low-speed operation, the motor can overheat due to reduced cooling efficiency. To prevent this, you can increase the gear ratio or switch to a 6-pole motor to allow the motor to operate at a higher frequency, thus improving cooling and reducing heat buildup. 3. The inverter should be installed in an environment that meets standard operating conditions to avoid malfunctions and extend its lifespan. The distance between the inverter and the motor should generally not exceed 50 meters. If longer distances are required, the carrier frequency should be reduced, or an output reactor should be added to ensure stable and safe operation.
