Model Code Definition

DKC: Product code of ECODRIVE full digital servo drive family

10.3: Hardware platform of CS compact low-power series

018: Nominal continuous output current: 18Arms

3: Low voltage variant, nominal DC bus 300V, AC input 200~240V single/three phase

MGP: Pre-installed control mainboard + factory fixed firmware, ready-to-run without extra firmware download

Technical Specifications

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

DC Bus: Rated 300VDC, overvoltage protection threshold 360VDC, integrated pre-charge and built-in brake circuit

Output Performance: 18A continuous rated current, 230% overload sustainable for 350ms, PWM carrier frequency 8kHz, max output frequency 1200Hz

Dimension & Weight: W35mm × H210mm × D210mm, net weight approx 2.9kg, IP20 cabinet vertical installation

Ambient Condition: Full-load operation 0~45℃; storage temperature -25℃~+80℃; altitude ≤1000m for full rating; ambient humidity＜95% non-condensing

Interface & Communication Configuration

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

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

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

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

Communication Port: RS232 front debugging port for DriveTop parameter setup; CANopen / Profibus / DeviceNet available via optional extension daughter board

Core Functions

Full closed-loop control of position / speed / torque integrated inside MGP standard firmware. Supports three operation modes: analog voltage speed regulation, pulse position control, internal multi-segment positioning triggered by digital input. Equipped with soft/hard limit protection, auto home return logic and brake timing control. Complete hardware fault protection: overcurrent, DC bus over/under voltage, power module overtemperature, encoder wire break, with numeric fault code display on front LED indicator.

Application Fields

Food packaging feeding axes, precision indexing rotary tables, electronic component assembling machines, small winding & cutting equipment, automated belt conveying and labeling die-cutting machinery.

Operation & Maintenance Instructions

This Type-3 low voltage model must only connect AC200~240V mains; connecting 380V high voltage will permanently damage internal power stage.

When replacing servo motor, auto motor parameter identification is available via DriveTop software with preloaded MGP firmware.

For frequent forward-reverse cyclic operation, install external high-power braking resistor to avoid overheat of internal brake unit.

Bare DKC10.3-018-3-FW empty base needs MGP control board mounted for full interchangeability with this unit.
