Siemens 6SE7023-8TD61 MASTERDRIVES Vector Inverter Unit

Module Feature

6SE7023-8TD61 is compact type DC-AC inverter of Siemens SIMOVERT MASTERDRIVES vector series.

Rated power 18.5kW, rated output current 37.5A, DC bus range 510~650V. It adopts IGBT power stage, matched with CUVC main control board, supports V/F open loop and field-oriented vector closed-loop control, compatible with incremental encoder feedback for high dynamic speed and torque regulation. It supports optional communication boards such as PROFIBUS, SIMOLINK for synchronous drive. Air cooling, IP20 protection, DIN rack installation. This legacy drive has been phased out by Siemens, widely stocked as emergency maintenance spare for paper, metallurgy, lifting and plastic machinery control cabinet.

Working principle

DC power from common DC bus or rectifier unit enters this inverter.

CUVC board generates PWM pulse signals to drive IGBT power module, converting DC into adjustable frequency three-phase AC for motor. Vector algorithm calculates motor flux and torque current separately according to encoder feedback. Built-in multi-level protection monitors overcurrent, overvoltage, overtemperature and motor overload, records fault codes and triggers stop command when abnormality occurs.

Onboard components

IGBT power module, DC bus capacitor bank, current sampling Hall sensor, gate drive circuit, cooling fan, backplane CUVC connector, PMU operation panel interface, status LED array and compact metal housing.

LED indicators

Front PMU panel displays operating value, fault code and parameter menu. Power and fault status LED are mounted on power unit and CUVC control board.

Hardware self‑diagnosis

Built-in supervision detects overcurrent, DC bus over/under voltage, heatsink overtemperature, encoder loss, communication failure and control board fault. Configuration and fault diagnosis are completed by Siemens SIMOVIS software.

Programming softwareSIMOVIS, used for motor parameter identification, vector loop tuning, communication parameter setting, fault waveform and fault log reading.
