DKC03.3-016-7-FW | Rexroth Indramat ECODRIVE03 Third Generation PROFIBUS Compact Bottom Mounting Base

Product Introduction The Indramat DKC03.3 of Leistritz is a third-generation optimized version of the PROFIBUS-DP bus FW bare power base. It is a compact small-power model. The body does not contain the main control board or pre-installed firmware. It supports three-phase AC380~480V high-voltage specifications, with a rated output of 16Arms. It requires the selection of MGP control card + firmware for the entire machine to operate. It is compatible with 1.5~5.5kW MKD/MAC small-power synchronous servo motors, mainly used for small packaging, automatic equipment components replacement. Compared with DKC03.1/03.2, it optimizes the internal circuit, reduces the machine body size, and improves the heat dissipation efficiency.

Description

Model Explanation

DKC: Indramat ECODRIVE03 servo drive controller

03.3: 03 = PROFIBUS-DP bus architecture, .3 = Third-generation optimized hardware model

016: Continuous rated output current 16Arms

7: High-voltage power supply specification, three-phase AC380~480V input, DC bus 700VDC

FW: Blank Base power-off base, without built-in control board, no factory firmware program

Technical Parameters

Main power supply: Three-phase AC380~480V ±10%, 50/60Hz; independent DC24V control power supply

DC bus: Rated 700VDC, overvoltage protection 850VDC

Output performance: Continuous 16Arms, peak 38.4A (240% rated overload 400ms), output frequency 0~1000Hz

Built-in braking: Built-in energy consumption braking circuit peak 2.8kW, external braking resistor required for frequent start-stop conditions

Dimensions: W55×H182×D170mm, net weight 1.8kg

Protection level: IP20 cabinet-mounted vertical installation, 0~45℃ full load, >45℃ reduced use, altitude ≤1000m

Compatible motors: MKD02/MKD04, MAC03~MAC05 series 1.5kW~5.5kW AC servo motors

Interface and Communication Configuration

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

Encoder interface: Special aviation feedback socket, compatible with rotary transformers, TTL incremental ABZ encoder

Board slot: Upper slot equipped with MGP main control card, leads DI/DO, ±10V analog, pulse direction instruction

Communication Ports

1. RS232 debugging port (activated by mounting): IndraWorks parameter debugging, firmware burning and upgrading

2. Standard card slot can be selected with DKC03.3-LK-PBK02 sub-card to achieve PROFIBUS-DP bus communication

3. expansion position can be added with CANopen communication sub-card Core function

The FW base only has the power inverter circuit, and all the control logic is implemented by the MGP control card.

The MGP card integration: ±10V analog speed regulation + pulse position + bus communication in one. It supports automatic control of electronic gears, zero-point return to zero, and motor brake timing when the motor is engaged.

Full hardware protection: overcurrent, overvoltage, undervoltage, module overheating, encoder break, output short-circuit fault shutdown alarm. Applicable scenarios

Small packaging machinery, precision assembly fixtures, small printing machines, automated conveying lines, micro CNC equipment (PROFIBUS bus control system)

Usage and Maintenance

1.7 High-voltage models are strictly prohibited from being connected to AC220V power supply. They are only suitable for three-phase 380V industrial power supply.

2. The FW bare base cannot be powered on and operated independently. It must be equipped with the MGP main control card and the matching firmware must be written.

3. The DKC03 full series of 016/040/100 power segments of the MGP card have common hardware and spare parts can be interchanged across power levels.

4. High-frequency reciprocating start-stop loads must be equipped with an external braking resistor to prevent the built-in braking circuit from overheating and being damaged.
