Model Explanation

DKC: Code for the ECODRIVE03 series servo drive products

10.3: CS Compact small-power hardware platform

012: Rated continuous output current 12Arms

3: Low-voltage model, bus DC300V, input single-phase / three-phase AC200~240V

MGP: Pre-installed main control board + factory-固化 firmware， not blank power base

01VRS： 01 firmware branch, VRS universal multi-functional firmware (distinguishes from dedicated V24 firmware， expands multi-segment programs， multi-bus compatibility) Technical Specifications

Main power supply: Single-phase / Three-phase AC 200~240V ± 10% 50/60Hz, independent DC 24V control power terminal

DC bus: Nominal 300VDC, built-in pre-charging, integrated built-in braking circuit

Output performance: 12A rated continuous, 230% overload can last for 350ms, PWM carrier 8kHz, maximum output frequency 1200Hz

Dimensions: W35×H210×D210mm, total machine net weight 2.3kg, cabinet IP20 vertical installation

Environmental conditions: Full-load operation at 0~45℃, altitude ≤ 1000m; storage at -25℃~+85℃, humidity < 95% without condensation

Interface and communication configuration

Power terminals: L1/L2/L3 three-phase (L/N single-phase) incoming lines, U/V/W motor power connection, external braking resistor connection position

Encoder interface: Standard TTL incremental ABZ encoder, compatible with rotary transformer feedback, built-in encoder 5V power output

Digital IO terminals: Multiple DI/DO, realize driver enable, positive/negative hard limit, origin search, motor brake timing linkage

Command port: ±10V analog speed control input, pulse + direction position command input

Communication interface: Panel RS232 debugging serial port (read/write parameters with DriveTop software); CANopen/Profibus/DeviceNet require selected communication sub-card to expand bus communication Core function

The VRS firmware adopts a three-loop closed-loop control system for position, speed and torque. It has three operating modes: analog voltage speed regulation, pulse position control, and I/O trigger 32-segment internal program automatic positioning. Compared with the V24 firmware, it optimizes program jumps and external trigger calling functions; integrates soft limit, hardware limit, and automatic return-to-origin logic; all hardware protection features: overcurrent, bus over/under voltage, power module overheating, encoder break wire, and phase loss faults self-locking; digital tube displays fault codes to directly show the fault type. Applicable scenarios

Food packaging feed shaft, electronic component assembly machine, precision rotary table indexing equipment, small winding and cutting machine, belt conveying automation equipment, label die-cutting equipment.

Usage and Maintenance

1. This model is of 3-phase low-voltage specification. It is strictly prohibited to connect to AC380V high-voltage power supply. Incorrect connection will directly cause power module breakdown;

2. Spare parts replacement should prioritize the same VRS firmware model. It is not possible to directly interchange with the parameters of the 01V24 firmware driver;

3. For high-frequency reciprocating start-stop loads, a large-power braking resistor must be externally connected to avoid overheating and damage of the built-in braking;

4. For debugging, use the DriveTop supporting software. Select the firmware version compatible with VRS, and the higher version software can be downward compatible for parameter reading.
