Model Code Definition

DKC = ECODRIVE full digital servo drive family

113 = Shortened notation of 11.3, Gen11 Rev3 hardware with expansion slot for option boards

040 = Continuous rated output: 40Arms

7 = High voltage version, 3-phase AC380~480V input, nominal DC bus 700VDC

FW = Standard universal factory firmware for basic three-loop control, no dedicated cam/electronic gearing functions

Technical Specifications

Main Supply: 3-phase AC380~480V ±10%, 50/60Hz; separate external DC24V for control power

DC Bus: Rated 700VDC, integrated pre-charge circuit and built-in dynamic brake unit

Output Rating: 40A continuous, 250% overload for 300ms, PWM carrier 8kHz, max output frequency 800Hz

Dimension & Weight: W65mm × H360mm × D215mm, net weight ~5.1kg, built-in cooling fan, IP20 DIN cabinet mount

Ambient: Full-load operating 0~40℃; storage -20℃~+80℃; rated altitude ≤1000m; humidity＜90% non-condensing

Interface & Communication Configuration

Power Terminals: L1/L2/L3 mains input, U/V/W motor output, external brake resistor terminal

Encoder Port: Dual feedback, compatible TTL incremental ABZ & resolver, onboard isolated 5V encoder supply

I/O Terminals: 8DI+8DO for enable, limit, home search and motor holding brake control

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

Communication: Front RS232 for DriveTop commissioning; Profibus-DP/CANopen/SERCOS via optional daughterboard

Core Functions

Full closed-loop position/speed/torque control; supports analog speed control, pulse positioning, digital-input triggered multi-step fixed positioning. Integrated STO safety function plus full protection against overcurrent, bus over/undervoltage, module overheat and encoder breakage with front LED fault codes. No embedded electronic cam compared to FM firmware variant.

Application Fields

General CNC feed axes, conventional rotary printing, medium-load winding/slitting machines, single-axis packaging and automated assembly equipment.

Operation & Maintenance Instructions

Type7 high voltage only for AC380~480V three-phase supply; 220V input leads to persistent undervoltage alarm.

Replace with same FW version; parameters not interchangeable with FM firmware drives.

Frequent cyclic forward/reverse operation requires external braking resistor to prevent internal brake overheat damage.
