DKC02.3-040-7-FW | Rexroth Indramat ECODRIVE03 High Voltage Servo Drive Original Equipment Manufacturer Part Number: R911279427

Product Introduction Leistritz ECODRIVE03 is a high-power three-phase 380V high-voltage bare-bottomed driver. The FW identifier indicates an empty hardware base, without a control card or pre-installed firmware. It needs to be later equipped with MGP/SGP control board and corresponding VRS firmware to be operational; the rated output is 40A, suitable for 7.5 - 15kW MAC/MSM series synchronous servo, with a standard SERCOS optical bus. It is mainly used for large-scale printing, extrusion equipment, and heavy-duty CNC original equipment replacement.

Description

Model Explanation

DKC02.3: ECODRIVE03 Second Generation SERCOS Fiber Drive Hardware Platform

040: Continuous rated output current of the driver 40Ams

7: High voltage specification, three-phase AC 380~480V input, DC bus 700VDC

FW: Bare machine without built-in firmware card, slot empty, control program and functions achieved through external control card Technical Specifications

Main power supply: Three-phase AC380~480V ±10%, 50/60Hz, bus DC700V

Control power supply: Independent DC24V auxiliary power supply

Rated output: Continuous 40Arms, short-time peak 96A (240% overload, 400ms)

Compatible motor: MAC11, MAC12, MSM10 high-power servo, compatible power 7.5kW~15kW

Feedback compatibility: Resolver resolver transformer + TTL incremental ABZ encoder dual feedback interface

Carrier frequency: 4kHz/8kHz selectable, maximum output frequency 1000Hz

Built-in braking: Built-in discharge circuit, peak braking power 10kW, maximum energy storage 5.0kWs, heavy load can be externally connected with high-power braking resistor

Dimensions: W90mm×H322mm×D198mm, net weight ≈5.4kg

Environment: IP20 cabinet installation, 0~45℃ full-load operation, altitude ≤1000m, humidity <90% RH without condensation

Interface and communication configuration

Power terminals: L1/L2/L3 three-phase incoming line, U/V/W motor power terminals, external braking resistor connection terminals

Slot positions:预留 control card slot on the upper part of the machine body, after inserting MGP/SGP, DI/DO, ±10V analog, pulse command terminals are led out

Encoder: Integrated composite aviation socket, resolver and incremental encoder shared

Communication interfaces

1. RS232 debugging port: Use IndraWorks to read and write parameters, flash firmware after installing control card

2. Dual SERCOS optical interface, multi-axis optical series synchronous networking

3. Slot can be expanded with Profibus/CANopen sub-communication card Core function

The bare board has no control logic. Its functions are determined by the optional control card:

SGP card: Only SERCOS bus positioning control, dedicated bus model

MGP card: ±10V analog speed regulation + pulse direction point position + three-in-one control of SERCOS bus, equipped with electronic gear, internal point position program, origin search, motor brake timing control; full hardware protection: overcurrent / overvoltage / undervoltage / overheating / encoder break wire / phase missing / stall fault protection Applicable scenarios

Large offset printing main drive shaft, extruder main drive,龙门 milling feed main shaft, high-power stretching for chemical fiber spinning, main servo of heavy-duty cutting equipment.

Usage and Maintenance

High-pressure models are only powered by AC380V and must not be connected to 220V low voltage (suffix 3 indicates 230V models)

The FW bare machine cannot be powered on and run alone. It must be equipped with MGP/SGP control card and the corresponding VRS firmware version must be written

DKC02.3-020/030/040 high-pressure hardware shells are universal. Control cards can be interchanged across power models

Replacement of spare parts should first check the original machine's firmware VRS version. If the versions do not match, the motor parameters need to be re-tuned.
