Specs

Device Type: Variable frequency drive Model: HDI 20S7A0000000000AAControl Mode: V/F control, vector control Controlled Object: Three-phase AC asynchronous motor Signal Interface: Digital I/O, analog input and output Protection: Overcurrent, overvoltage, undervoltage, overtemperature Installation: Cabinet mounting Cooling: Built-in air cooling

Principle

The HDI 20S7A0000000000AA converts input AC power into DC power through the internal rectifier bridge. The inverter module converts DC power into adjustable frequency and adjustable voltage AC power to drive the motor. The main control unit collects current and voltage signals in real time and adjusts the output waveform according to the speed command. When fault signals are detected, the HDI 20S7A0000000000AA will stop output and lock the fault code.

Applications

The HDI 20S7A0000000000AA is used for speed regulation of fans, pumps and conveyor belts. It serves motor drive control for packaging machinery and textile equipment. The HDI 20S7A0000000000AA applies to equipment renovation and spare part replacement in industrial production lines. It also supports flow and pressure adjustment in water treatment and HVAC systems.
