Model Code Definition

DKC = ECODRIVE03 full digital servo drive family

XX.3 = Hardware revision V3, different XX correspond to forced air cooling/natural cooling and optional fieldbus daughterboard slot configuration

100 = Continuous rated output current:100Arms

7 = High voltage grade, 3Φ AC380~480V input, nominal DC bus 700VDC

FW = Standard basic firmware, exclude advanced synchronous motion functions (FM version owns cam & gearing function)

Technical Specifications

Main Power Supply:3-phase AC380~480V ±10%,50/60Hz; independent external DC24V auxiliary control power(26W power consumption for control circuit)

DC Bus:Nominal 700VDC, built-in 24Ω soft-start precharge resistor and internal dynamic brake unit

Output Performance:100A continuous current, 250% overload sustain 300ms; selectable 4kHz/8kHz PWM carrier, max output frequency 1000Hz, max output voltage 800V

Dimension:H360mm × W105mm × D261mm, net weight 9.7kg, IP20 cabinet vertical DIN mounting

Ambient Condition:Full load operation 0~45℃, derated run up to 55℃; storage -35~+85℃; installation altitude ≤1000m; RH＜90% non-condensing

Interface & Communication Configuration

Power Terminals:Heavy-duty high-current terminals for L1/L2/L3 mains input, U/V/W motor output, dedicated terminal for external high-power braking resistor

Encoder Port:Dual 15pin D-SUB interface, support TTL incremental ABZ encoder + resolver dual feedback, isolated internal 5V encoder supply

Digital I/O:Standard DI/DO terminals for drive enable, hardware limit switch, homing trigger, motor holding brake sequential logic control

Analog Command:±10V analog speed/torque reference input, pulse+direction position command port

Communication:Front RS232 for DriveTop parameter commissioning; Profibus-DP/CANopen/SERCOS optional via add-on daughterboard based on actual XX hardware code

Core Functions

Full closed-loop triple control:position/speed/torque regulation; support analog speed control, pulse positioning, DI triggered multi-step fixed positioning. Integrated STO safe torque-off, complete fault protection for overcurrent, DC bus over/undervoltage, IGBT overheat, encoder break, front panel LED fault code indication. FW firmware removes electronic cam curve and master-slave synchronization functions compared with FM variant.

Application Fields

Heavy-duty fabric/film winding-slitting production line, large rotary printing machine, heavy-load CNC feed axes, forging automation and large automatic packaging equipment.

Operation & Maintenance Instructions

Type7 high voltage model strictly for 3Φ AC380~480V input; single-phase 220V wiring will trigger persistent bus undervoltage alarm and insufficient output torque.

Reserve sufficient cabinet ventilation gap per confirmed XX specification to avoid overheat derating or shutdown.

Frequent forward-reverse reciprocating heavy load must configure matched external high-power braking resistor to prevent internal bleeder burnout.

Parameter tuning needs matching DriveTop software edition for FW firmware, parameters cannot be directly copied from FM firmware drives.
