Model Code Definition

DKC = ECODRIVE03 full digital servo drive family

XX.3 = V3 hardware revision; different XX correspond to natural cooling/forced air cooling and optional daughterboard expansion slot layout

200 = Continuous rated output current:200Arms

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

FW = Standard basic firmware, excludes advanced electronic cam curve & synchronous master-slave functions (FM version equips above advanced motion functions)

Technical Specifications

Main Power:3-phase AC380~480V ±10%,50/60Hz; independent external DC24V control auxiliary power, control circuit power consumption≈29W

DC Bus:Nominal 700VDC, built-in 24Ω soft-start precharge resistor & integrated internal dynamic brake unit, peak bleeder power 120kW(0.5s/60s)

Output Index:200A continuous output, 250% overload sustain 300ms; optional 4kHz/8kHz PWM carrier, max output frequency 800Hz, max output voltage 800V

Dimension&Weight:Dimension varies per XX code; DKC03.3 size H360×W230×D261mm, net weight≈19.5kg; IP20 vertical cabinet DIN mounting

Ambient Requirement:Full-load operation 0~45℃, derated running up to 55℃; storage -30~+85℃; installation altitude ≤1000m; RH＜95% non-condensing

Interface & Communication Configuration

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

Feedback Port:Dual 15pin D-SUB encoder interface, compatible with TTL incremental ABZ encoder + resolver dual feedback, isolated onboard 5V encoder power supply

Digital I/O:Standard DI/DO terminal block for drive enable, hardware limit signal, homing trigger, motor holding brake sequential control

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

Communication:Front RS232 for DriveTop parameter commissioning; Profibus-DP/CANopen/SERCOS available via optional daughterboard based on specific XX hardware type

Core Functions

Three closed-loop regulation (position/speed/torque); support analog speed control, pulse positioning, DI multi-step fixed positioning; integrated STO safe torque-off protection. Full fault alarm including overcurrent, DC bus over/undervoltage, power module overheat, encoder open-circuit, fault code displayed via front panel LED. FW firmware removes electronic cam and master-slave synchronization compared with FM variant.

Application Fields

Heavy-duty film/fabric slitting & winding production line, large rotary printing machine, heavy-load CNC main spindle, metallurgical processing automation, oversized gantry handling equipment.

Operation & Maintenance Instructions

Type7 high voltage model only for three-phase 380~480V AC input; single-phase 220V wiring triggers persistent DC bus undervoltage fault and insufficient output torque.

Reserve ≥80mm upper & lower cabinet ventilation clearance according to XX specification to avoid over-temperature shutdown and power derating.

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

Parameter tuning requires DriveTop software version matching FW firmware; parameter files cannot be directly copied from FM-version servo drives.
