FC300 series inverter technical specifications:

1. Frequency control Frequency range: 0.0Hz-1000.0Hz Control accuracy: digital setting 0.01Hz; analog input 0.1Hz Keyboard setting method: 0.01Hz; △▽ setting; keyboard encoder setting Analog setting mode: external voltage signal 0-10V; external current signal 4-20mA Other functions: minimum operating frequency, minimum output frequency, stop frequency, jump frequency can be set separately 2. General control Acceleration and deceleration control: four-stage acceleration and deceleration time (.0-3000.0S) arbitrarily selected V/F minimum output voltage: the minimum starting voltage value of the V/F curve can be set (0-30%) Multi-function input terminals: 8 multi-function input terminals (X1-X8), of which X8 is a high-speed input terminal Multi-function output terminal: a group of relay normally open output, a group of relay normally open normally closed output, to realize the indication and alarm of operation, zero-speed target frequency arrival, arbitrary frequency arrival, counting, fault output, etc. Other functions: AVR function, free stop, DC brake, automatic reset and restart, PLC program control, external counting, etc. 3. Protection function Overload protection: 150% for one minute, 200% for immediate overcurrent Overvoltage protection: 220V line: DC bus >400V; 380V line: DC bus >800V; Undervoltage protection: 220V line: DC bus
