Model Explanation

DKC: ECODRIVE Digital Servo Power Amplifier Series

01.1 (abbreviated as 1.1): The first generation of ECODRIVE01 hardware platform

030: Rated continuous output current 30Amps

3: 300VDC low-voltage bus, AC 200~240V power supply model

FW: Bare power base without built-in firmware. The firmware needs to be ordered separately and rewritten later Technical Specifications

Main power supply: Single-phase / Three-phase AC 200~240V ± 10%, 50/60Hz, incoming line rated 22A; Independent DC 24V control power supply

DC bus: Nominal 300VDC, Overvoltage protection 360VDC, Built-in pre-charge and basic braking power circuit

Output performance: Continuous rated 30A, 230% short-term overload 350ms, Carrier 8kHz, Maximum output frequency 1200Hz

Braking configuration: Built-in small power braking unit, No external braking resistor for light load, External resistor required for high-frequency start-stop

Dimensions: Width 70mm × Height 210mm × Depth 210mm, Net weight 5.0kg, IP20 cabinet protection

Environmental parameters: Full-load operation at 0~45℃, Altitude ≤ 1000m; Storage - 25~+80℃, Humidity < 95% without condensation

Interface and communication configuration

Power terminals: L/N single-phase, L1/L2/L3 three-phase incoming line, U/V/W motor power connection, Braking resistor connection position

Encoder interface: Compatible with TTL incremental ABZ, rotary transformer feedback, Built-in encoder power output

Control terminals: Green terminals DI/DO limit, origin, enable, brake linkage, ±10V analog quantity, pulse direction instruction

Communication ports

1. RS232 debugging serial port: Firmware burning and parameter debugging (activated after firmware loading)

2. Basic position interface, 32 internal preset positioning programs can be enabled after flashing ASE firmware

3. No native bus, CANopen/Profibus require additional expansion card Core function

The main body only consists of power inverter hardware. The three-loop control and positioning logic are all achieved by writing ASE firmware;

After writing the corresponding firmware, it supports: ±10V analog speed regulation, pulse point position, I/O triggering of internal program positioning, origin search, brake sequence control;

The hardware is equipped with full protection: IGBT short circuit, output overcurrent, bus over/under voltage, module over-temperature, encoder broken wire fault shutdown, and dual digital tube fault code display on the panel. Applicable scenarios

Small packaging equipment feed axis, desktop CNC engraving machine, component assembly machine, small winding and cutting equipment, retrofit of old production line spare parts.

Usage and Maintenance

1.3 Models with suffix "low voltage" must not be connected to AC380V power supply; incorrect connection will directly cause power module breakdown;

2. Bare base of FW without firmware cannot be powered on; it is necessary to use the corresponding ASE firmware (ASE02VRS/ASE04VRS) to download the program using DriveTop;

3. For large inertia loads that are frequently started and stopped, it is recommended to install an external braking resistor to prevent the built-in braking from overheating and damaging;

4. DKC1.1-FW has the same installation size as the complete machine without FW (DKC1.1-030-3), but the complete machine comes with firmware; the two cannot be directly interchanged.
