inverter speed value .
In the realm of modern technology, the concept of “inverter speed value” has emerged as a pivotal factor in the efficient operation of various electronic devices and systems. As we delve into this intricate subject, we aim to provide an in-depth, comprehensive understanding of this crucial component, its functionality, and its impact on the overall performance of the system it is integrated into.
The inverter, a fundamental element in the realm of power electronics, plays a significant role in converting direct current (DC) into alternating current (AC). The speed value of an inverter, often referred to as the frequency, is a critical parameter that determines the rate at which the AC output oscillates. This frequency, measured in Hertz (Hz), directly influences the speed of the AC motors that the inverter powers.
The inverter speed value is not a static figure; it can be adjusted to meet the specific requirements of the application it serves. This ability to control the speed value of an inverter is what makes it an indispensable tool in various industries, from renewable energy systems to electric vehicles and HVAC systems. By manipulating the inverter speed value, we can optimize the performance, efficiency, and lifespan of these systems, leading to significant energy savings and reduced operational costs.
Understanding the intricacies of inverter speed value requires a deep dive into the principles of power electronics and motor control. The speed value of an inverter is determined by the switching frequency of the power devices within the inverter circuit. These power devices, typically transistors or IGBTs, switch on and off at a rapid pace, creating a waveform that mimics the sinusoidal nature of AC power. The rate at which these devices switch is what determines the inverter’s speed value.
The ability to control the inverter speed value has revolutionized the way we use and manage energy. In renewable energy systems, for instance, inverters with variable speed values allow for maximum power point tracking (MPPT), enabling these systems to extract the maximum possible power from sources like solar panels and wind turbines. In electric vehicles, the inverter speed value is adjusted to control the speed of the vehicle, providing smooth acceleration and deceleration. In HVAC systems, inverters with variable speed values ensure optimal temperature control while minimizing energy consumption.
In conclusion, the inverter speed value is a critical parameter that influences the performance and efficiency of various electronic systems. By understanding and controlling this value, we can optimize these systems, leading to significant energy
Enable /disable integral value during ace/decal , 0: disable (the integral function is not used while accelerating or decelerating : it is used at constant speed). 1: enabled (the integral function is used at all times),
note: when v/f control with pg feedback is used integral control during acceleration and deceleration can be enabled or disabled with f 1-0 7, set f i-0 7 to 1 , (integral control enabled) if you want to keep the motor speed as close to the frequency reference as possible during acceleration and deceleration . set f 1-0 7 to 0,(integral control disabled) if you want to prevent the occurrence of overshooting / undershooting .
OVER SPEED/EXCESSIVE SPEED
To set the detection method of over speed ( os) .
note: when frequency exceeds the value set in f1-08 (set in unit of 1%with the maximum output frequency taken as 100 %) and it lasts more than f1-09 (diction time seconds) the over speed will be detected.
detection method for over speed deviation .
note: constant fi-10 sets the pg speed deviation detection level as a percentage of the maximum output frequency . constant f1-11 sets the length of time in seconds that the difference between the motor speed and reference speed must exceed the pg speed deviation detection level in order to detect a pg speed deviation.
PG ROTATION .
To set the pg rotation direction . 0:phase a leads with forward run command (please b leads with reverse run command ) 1: phase b leads with forward run command .(phase a leads with reverse run command ).
note : this constant is used to coordinate the pg ,s rotation direction with the motor,s rotation direction generally direction (looking from the input axis ). when a forward reference is output the motor rotation in the counterclockwise direction ( looking from the input axis ).when the motor is in forward rotation please set pg ,s output is phase a leas or phase b leads.
PG DIVISION RATE ( PG PULSE MONITOR ).
Sets the division ratio for the pg speed control card pulse output .
note : this constant is only effective when a pg-b2 is used it sets the division ratio used when the pulse monitor output is connected to a pulse input device . the first digit in the setting (0 or 1) is n and the second two digits ( 01 to 32 ) are m . the division ratio is calculated from n and m with the following equation , division ratio = (1+n )/m setting range n:0, 1m :1 to 32. possible division rate settings are as follows :1/32<f1 -06 <1. for example , if the division rate is :1/2 (a setting of ,2, ),the monitor output will be falf of the number of pulse output from the pg .
