Siemens 6SE6420-2AB21-5BA1 Frequency Converter MICROMASTER 420 1.5 kW 200-240 VAC without AOP/BOP

1. Overview of the Siemens 6SE6420-2AB21-5BA1

The Siemens 6SE6420-2AB21-5BA1 is a micro inverter. It packs a powerful 1.5 kW of power into a compact package measuring 202 × 149 × 172 mm. It features a single-phase 200–240 V input, 14.4 A output, and stepless speed regulation from 0–550 Hz, allowing fans, pumps, and conveyors to operate smoothly from low to high speeds. With a built-in Class A filter and EN 55011 Class A certification, it can be installed directly in civilian applications like food packaging machines and woodworking saws to pass EMC testing without the need for additional shielding.

Flux Current Control (FCC): Provides high torque at low speeds and fast dynamic response.
Fast Current Limiting (FCL): Automatically limits current to prevent overcurrent tripping.
DC Injection Braking: Rapidly stops the motor without an external braking unit.
8-Speed + PID: Enables multi-speed, closed-loop constant voltage/constant current control via the control panel or communication.
Parameter Cloning: Supports batch parameter copying via the optional operator panel (BOP-2, AOP) or RS-485 (USS/Modbus RTU).
Plug and Play: Start the motor with factory default parameters, with commissioning time less than 5 minutes.
