ZVF300 Series Frequency Inverter is new product in ZIRI Company.
ZVF300 series frequency inverter applied at the metallurgy, plastomer, textile, food-stuff, petroleum, chemical industry, paper-making, pharmacy, printing, building material, crane and all kinds of machine equipment. As AC asynchronous motor's driving and speed control.
ZVF300 Series frequency inverters are high performance open loop vector inverters for controlling asynchronous AC induction motors and permanent synchronous motors.
|Control Function||Automatic energy-saving operation||Auto optimize V/F curve according to the load changes to realize the energy saving operation.|
|Auto voltage regulation(AVR)||When the network voltage changes, it can regulate PWM output automatically to maintain constant voltage.|
|Built-in PID||This can form a convenient closed-loop control system (CLCS)and is applicable to pressure control, flow control and other process control .|
|Operation Function||Operating command||Operation panel control ,external terminal control and COM control|
|Frequency setting||Keypad potentiometer setting , operation panel UP ,DOWN setting,. external terminal UP/DOWN setting, analog voltage signal or external potentiometer setting , analog current signal setting .terminal combination setting ,485 COM setting and so on.|
|Input Signal||Forward/Reverse signal\multi-speed signal \fault signal \|
reset signal etc.
|Output signal||Programmable relay\open collector output \Fault signal output.|
|Multi-function analog and digital output terminal||This can realize the output of frequency current and other physical quantity by output 0-10V or 0-20mA DC signal and 0-10KHz digital signal output.|
|Braking function||Dynamic braking||With an external braking resistor, the maximum braking torque may reach 100%.|
|DC Braking||This can be selected when the motor starts or stops with the action frequency of 0-20Hz,action current level of 0-100% and actuation time of 0-30sec., which can be set in sequence.|
|Other Function||Skip frequency\Jog function\Counter \Rotation speed tracking\Momentary power loss restart \Frequency upper/lower limiting\Acceleration/ Deceleration mode can be adjusted \Frequency meter and Voltmeter output \Multi-speed/ program running \Two wire mode/ three wire mode control \Wobble frequency control\Multi-function input terminal selection \Fault auto reset\RS485 serial communication .|
|Protection Function||Input phase loss protection\Over current protection \Overload protection\Over voltage protection \Under voltage protection\Over heat protection ect.|
