What are inverter settings?
Inverter Settings 1. To set output voltage of inverter - This is normally 230 Vac. Possible values 210V ~ 245V. 2. Used to enable/disable the internal ground relay functionality. Connection between N and PE during inverter operation. - The ground relay is useful when an earth-leakage circuit-breaker is part of the installation.
How does an inverter control a motor?
An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.
How does an inverter work?
The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control. The inverter outputs a pulsed voltage, and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor.
What causes overvoltage in an inverter?
This phenomenon is known as regeneration. If the regenerative energy is too large to be stored in the inverter, it causes an overvoltage. Regenerative processing uses the braking circuits built into the inverter to convert the regenerated energy into heat via resistors, preventing an overvoltage.
How to select an inverter?
Basically, select an inverter which fits the maximum applicable motor capacity of the selected motor. After selecting an inverter, check if it meets the both of the following conditions. If not, select an inverter with one size larger in capacity and check again. Note: 1.
How does an inverter affect the speed of an AC motor?
The use of an inverter to adjust the speed and acceleration of an AC motor increases the range of applications of the motor compared with a motor that operates at a constant speed. The speed of a motor is normally measured as the number of revolutions per minute (rpm).
