Model Explanation

DKC: ECODRIVE03 Full Digital Servo Drive Series

03.3: 03 = Native PROFIBUS-DP hardware platform, .3 = Third-generation optimized hardware variant

040: Continuous rated output current 40A

None - 3/-7: Voltage specifications not fixed, the hardware power circuit is compatible with both 300V/700V DC bus systems

FW: Blank Base Power Base, does not include control motherboard, no factory-固化 driver firmware Technical Specifications

Main circuit power supply:

With MGP-3 card: Three-phase AC 200~240V ± 10%, DC bus 300VDC

With MGP-7 card: Three-phase AC 380~480V ± 10%, DC bus 700VDC

Control power supply: Independent DC 24V/2A

Output capacity: Continuous 40Arms, Peak 96A (240% short-term overload 400ms), Output frequency range 0~1000Hz

Built-in energy consumption braking: Peak 8.5kW, High-frequency reciprocating load requires external braking resistor

Overall size: W65×H360×D261mm, Net weight 6.5kg, IP20 cabinet installation

Environment: 0~45℃ full-load operation, Altitude ≤1000m, Overheating load reduction

Interface and communication configuration

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

Encoder socket: Special aviation feedback port, Compatible with rotary transformers, TTL incremental ABZ encoder

Top card slot: Assembly of MGP main control card, Card body outputs DI/DO switch quantity, ±10V analog speed regulation, Pulse direction instruction

Communication interfaces

1. RS232 debugging serial port (MGP card enabled): IndraWorks parameter debugging, firmware burning

2. Built-in PROFIBUS-DP bus interface

3. Card slot can be optionally equipped with CANopen expansion sub-card Core function

The base only has the power inverter hardware. All the control logic is implemented by the MGP main control card. By replacing the MGP-3/MGP-7, you can switch between 220V/380V power supply systems.

Control mode: ±10V analog speed regulation + pulse position + PROFIBUS bus control in a three-in-one configuration. It supports electronic gear synchronization, origin search, and motor brake timing control.

Hardware full protection: overcurrent, overvoltage, undervoltage, module overheating, encoder break, and inter-phase short circuit faults causing machine shutdown. Applicable scenarios

Replacement and repair of imported old machine tools, printing machinery, rubber and plastic auxiliary machinery, multi-axis winding production line drives, as well as cross-voltage equipment retrofit with base structure.

Usage and Maintenance

1. This model cannot be powered on directly. It must be equipped with the corresponding voltage level MGP main control card + matching firmware. MGP-3 requires a 220V incoming line, MGP-7 requires a 380V incoming line. Incorrect power supply must not be used.

2. It can directly replace the two standard models DKC03.3-040-3-FW and DKC03.3-040-7-FW. Only the main control card needs to be replaced.

3. Frequent forward and reverse rotations, large inertia conditions, mandatory external connection of large power braking resistors to prevent overheating and damage of the built-in braking circuit.
