Note:
- The single phase motor should Not be adjusted to run based on a lower frequency than 80% of its rated frequency for along time, otherwise the motor may fail.
- RDDLZ VFD Cannot be used as a power source, it Can only be directly connected to an induction motor to control the motor speed.
- Single phase VFD Cannot control the motor in reverse, if you want to reverse the motor, refer to the motor nameplate instructions for operation.

Tips: Irrational application in variable frequency drive energy-saving
The variable frequency drive is a power-saving control product, but it can't be used to save energy in every occasion. In fact, the VFD is able to save energy through adjusting the motor speed, and it has slightly higher efficiency and power factor than other speed control equipment. If the variable frequency drive can achieve energy saving is determined by the speed characteristics of the load.
For centrifugal fans or centrifugal pumps loads, the torque is proportional to the square of the speed, and the power is proportional to the cube of the speed. As long as uses the valve to control the flow, and not in full load operating, using speed control operation can achieve energy saving. When the speed dropped to 80% of the original, the power is only 51.2%of the original. We can see that the VFD has obvious energy saving effect in this type of load applications. For Roots blower loads, the torque is independent of the magnitude of the speed, that is, it is constant torque load. The original uses exhaust valve to discharge excess air flow and to adjust the air volume, if uses speed control operation, it can also achieve energy saving. When the speed dropped to 80% of the original, the power will drop to 80%, the energy-saving effect is much lower. For constant power loads, power is independent of the speed. Such as the ingredients belt scale, under the set flow conditions, when the material layer is thick, the belt speed down. When the material layer is thin, the belt speeds up. In this type of load applications, the VFD cannot achieve energy saving.
