The speed control is smooth and efficient. At low speeds, the characteristic static rate is higher, and the relative stability is good.
The operating temperature for variable frequency drives typically ranges from -10℃ to 40℃, with humidity levels below 90% for optimal performance. If the environmental temperature exceeds 40℃, the drive should be derated by 5% for every degree above. For every 10℃ increase in temperature, the lifespan of the drive is halved. Therefore, ensuring proper surrounding environmental temperature and heat dissipation for the drive is crucial.
All power supply products, including variable frequency transformers and voltage stabilizers, should be kept away from fire sources and high temperatures to prevent overheating.
Prevent oil mist and salt from eroding variable frequency power supplies.
Please place the variable frequency power supply in a well-ventilated area, ensuring it is at least 30 cm away from other objects to maintain proper ventilation of the intake openings.
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 damp area.
Do not place 60Hz power supplies, 400Hz power supplies, and other various power supply products on uneven or inclined surfaces.
Inverter drives will increase losses when compared to AC power sources, leading to reduced cooling efficiency at low speeds and increased motor temperature rise. Therefore, it is advisable to decrease the motor's torque load at low speeds. When the motor operates at high speeds (above 60Hz), changes in electromotive force balance and bearing characteristics occur.
