Model Explanation

DKC02.3: ECODRIVE03 with SERCOS optical bus hardware platform as standard

016: Rated continuous output current 16Arms

7: Seventh-generation power hardware version

FW: Base firmware bare board, without pre-installed dedicated control firmware, can be equipped with MGP/SGP/other firmware modules Technical Specifications

Continuous output current: 16 Arms, peak 38.4A (400ms short-term overload)

Main power supply: Three-phase AC 200~240V 50/60Hz; DC bus 300VDC

Control power supply: Independent DC 24V power supply, fault codes are saved when the main circuit is powered off

Motor power compatibility: Rated 1.1kW~1.5kW, maximum instantaneous output power approximately 5.2kW

Output voltage: AC 0~230V, maximum output frequency 333.3Hz

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

Brake configuration: Built-in power discharge resistor, external external braking resistor can be connected for high-power loads

Dimensions: W70mm×H230mm×D180mm, net weight approximately 1.8kg

Environmental conditions: Full-load operation at 0~45℃, reduced power at 45~55℃; humidity ≤ 90% RH without condensation, IP20 cabinet-mounted vertical installation

Interface and communication configuration

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

General I/O terminals: DC 24V power supply, servo enable, fault reset, hard limit DI, ready/fault DO, ±10V analog instruction, pulse direction input

Encoder composite socket: Incremental encoder + resolver shared integrated interface

Communication ports

1. RS232 debugging port: IndraWorks/DriveTop debugging, firmware download and writing

2. Standard SERCOS optical interface, multi-axis optical series synchronization

3. Slot reserved: After installing MGP card, Profibus/CanOpen bus communication can be expanded Core function

The FW bare board has no solidification control program. After installing the corresponding firmware card, the function can be enabled:

With MGP: supports analog quantity, pulse, SERCOS three-axis instructions, point program, electronic gear, origin search

With SGP: only dedicated control for SERCOS bus

Full loop hardware protection: overcurrent, overvoltage, undervoltage, overheating, encoder break, phase missing, motor locked rotor alarm; comes with brake timing control, parameter EEPROM power-off preservation. Applicable scenarios

Numerical control milling machine feed axis, textile winding servo, rubber and plastic extrusion traction axis, printing high-speed cutting main axis.

Usage and Maintenance

1. Only three-phase AC220V power supply is allowed. Do not connect 380V power source.

2. Replacement of new machines must install corresponding firmware cards (MGP/SGP). Without firmware, it cannot run.

3. Hardware of the same series DKC02.3-004/008/012/016 can be interchanged. After replacement, firmware + motor parameter setting must be reconfigured.

4. Class F faults should be prioritized to check the power cables, encoder shielding lines, and 24V control power supply.
