The speed adjustment offers smooth performance with high efficiency. At low speeds, the characteristic static shutdown rate is higher, resulting in better relative stability.
2. Variable frequency drives are generally suitable for operating temperatures between -10℃ and 40℃, with humidity levels below 90%. When the ambient temperature exceeds 40℃, the drive should be derated by 5% for every 1℃ increase. For every 10℃ rise in temperature, the lifespan of the drive is halved. Therefore, it is crucial to address the issues of surrounding ambient temperature and the drive's heat dissipation.
All power supply products, including variable frequency transformers and voltage stabilizers, should be kept away from fire sources and high temperatures to prevent excessive heat.
4. Prevent oil mist and salt from eroding the variable frequency power supply.
Please place the variable frequency power supply in a well-ventilated area, ensuring at least 30 cm of clearance around it to maintain proper ventilation of the intake ports.

6. The normal operating environment for the variable frequency power supply is a temperature range of 0℃ to 40℃, and humidity of 0% to 90% (non-condensing state).
Avoid placing variable-frequency power supplies in areas with corrosive gases, vibration, or magnetic interference.
Avoid placing the variable frequency power supply in direct sunlight, under rain, or in a humid area.
Do not place 60Hz power sources, 400Hz power sources, and other various power products on uneven or inclined surfaces.
10. When a variable-frequency inverter drives a standard motor, compared to line frequency power, there will be an increase in losses, a deterioration in cooling performance at low speeds, and an increase in motor temperature rise. Therefore, the motor's load torque should be reduced at low speeds. When the motor operates at high speeds (above 60Hz), the electromotive force balance and bearing characteristics will change.
