Model Code Definition

DKC = ECODRIVE03 full digital servo drive family code

10-3 = Alternative writing of 10.3, CS compact low-power hardware platform

018 = Rated continuous output current: 18Arms

3 = Low voltage specification, AC input single/three-phase 200~240V, rated DC bus 300VDC

MGP = Pre-mounted main control board with factory fixed firmware (non-empty base unit)

01VRS = V01 universal general-purpose firmware, supports internal segmented positioning program operation

Technical Specifications

Main Power Input: Single/Three-phase AC200~240V ±10%, 50/60Hz; separate external DC24V for control power supply

Interface & Communication Configuration

Power Terminals: L/N single-phase or L1/L2/L3 three-phase mains input, U/V/W motor power output, external brake resistor terminal block

Encoder Port: Compatible with TTL incremental ABZ encoder & resolver, onboard 5V encoder power output

Digital I/O Terminal: Multi DI/DO for drive enable, positive/negative hardware limit, home search and motor holding brake sequential control

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

Debug & Fieldbus: Front RS232 serial port for DriveTop parameter debugging; CANopen/Profibus/DeviceNet expandable via optional daughterboard

Core Functions

01VRS general firmware integrates full closed-loop control of position/speed/torque; three optional running modes: analog voltage speed regulation, pulse position control, digital-triggered 32-segment internal automatic positioning. Equipped with soft/hard travel limit, auto homing and brake delay logic; complete fault protection against overcurrent, DC bus over/undervoltage, power module overheat and encoder wire break, with front LED numeric fault indication.

Application Fields

Food packaging feeding axes, precision rotary indexing tables, electronic component assembling equipment, winding/cutting machinery, automatic labeling die-cutting and belt conveyor automation systems.

Operation & Maintenance Instructions

Type-3 low voltage model only allows AC200~240V input; 380V high voltage connection will permanently damage internal power stage.

Replacement must adopt same 01VRS firmware variant; parameters cannot be directly copied from V24 firmware drives.

External high-power braking resistor is required for frequent forward-reverse cyclic operation to avoid built-in brake overheating failure.

Parameter commissioning needs DriveTop software version matching with 01VRS firmware revision.
