Model Code Definition

DKC: ECODRIVE full digital servo drive series identifier

113: Shortened marking for 11.3 (Gen11 Revision3 hardware with option card expansion slot)

40: Abbreviation of 040, rated continuous output current = 40Arms

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

FW: Standard universal factory firmware, basic 3-loop control without electronic cam/gearing functions (differs from FM)

Technical Specifications

Main Power: 3-phase AC380~480V ±10%, 50/60Hz; independent external DC24V control supply

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

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

Mechanical Data: W65mm × H360mm × D215mm, net weight ≈5.1kg, internal cooling fan, IP20 DIN cabinet mounting

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

Interface & Communication Configuration

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

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

Digital I/O: 8DI+8DO for drive enable, hardware limit, home search and holding brake logic control

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

Debug & Fieldbus: Front RS232 for DriveTop parameter setup; Profibus-DP / CANopen / SERCOS via optional daughterboard

Core Functions

Full closed-loop position/speed/torque regulation; three operation modes: analog speed control, pulse positioning, DI-triggered multi-step fixed positioning. Equipped with STO safe torque off and complete protection: overcurrent, bus over/undervoltage, IGBT overheat, encoder break, front LED fault code display. No native electronic cam or master-slave sync compared with FM firmware.

Application Fields

General CNC feed axes, rotary printing machines, medium-duty winding & slitting equipment, single-axis packaging and automated assembling machines.

Operation & Maintenance Instructions

Type7 high-voltage unit only connects 3-phase AC380~480V; wrong 220V input triggers permanent undervoltage alarm and insufficient torque.

Replacement needs same FW firmware; parameters cannot be copied directly from FM-version drives.

Frequent forward/reverse cyclic application must add external high-power braking resistor to avoid internal brake overheat damage.

Parameter commissioning requires matching DriveTop software revision for FW firmware read/write.
