Model Explanation

DKC: ECODRIVE Servo Power Drive Series

1.3 = 01.3: ECODRIVE03 The Third Generation Hardware Platform (upgraded version, different from the first generation 1.1)

040: Rated Continuous Output Current 40Amps

7: 700VDC High Voltage Bus, Three-phase AC380~480V Industrial Grid Specification

FW: Empty Base without Factory Pre-installed Firmware, Control Program Burned Separately Later Technical Specifications

Main power supply: Three-phase AC380~480V ±10%, 50/60Hz, incoming line rated 16A; independent DC24V control power supply, control power consumption 21W

DC bus: Nominal 700VDC, built-in pre-charge circuit, integrated energy consumption braking, braking peak power 10kW

Output performance: 40A continuous rated, 230% overload 350ms, PWM carrier 8kHz, maximum output frequency 1000Hz

Dimensions: Width 65mm × Height 360mm × Depth 261mm, net weight 5.1kg, IP20 cabinet protection

Environmental conditions: Full-load operation at 0~45℃, reduced-load operation at 45~55℃, installation altitude ≤1000m; storage - 25~+80℃, humidity < 95% without condensation

Interface and communication configuration

Power terminals: L1/L2/L3 three-phase incoming lines, U/V/W motor power connection, external braking resistor connection position

Encoder interface: Fully compatible with TTL incremental ABZ, resolver, HIPERFACE, EnDat absolute value encoder, with built-in encoder power output

Control terminals: Modular plug-in IO sub-card, standard DI/DO limit, origin, enable, brake sequence, ±10V analog quantity, pulse direction instruction

Communication ports

1. RS232 debugging serial port: Only used for DriveTop firmware download, parameter setting, after firmware installation communication takes effect

2. Bus optional: CANopen, Profibus-DP, SERCOS require installation of corresponding communication expansion board card, supports ESM storage card offline parameter copy Core function

The hardware is only effective in the power inverter circuit. The three-loop servo and point position logic completely rely on firmware. After installing the firmware, it supports three control modes: analog speed regulation, pulse point position, and internal program positioning.

Hardware full protection: IGBT short circuit, output overcurrent, bus over/under voltage, module overheating, encoder breakage fault locking, display of panel digital tube fault codes;

Unique feature of the 03 generation: Optional ESM program storage card. The entire machine parameters can be backed up offline. Simply replace the base and insert the card to use it immediately, without the need to reflash the firmware. Applicable scenarios

Printing equipment main drive, heavy packaging machinery feeding, CNC grinding machines / machining centers feed axes, fully automatic winding machines, lithium battery cutting equipment, retrofitting and replacement of old Indramat equipment.

Usage and Maintenance

1. The suffix 1.7 high-voltage base must not be connected to single-phase AC220V. Incorrect connection will directly cause power module breakdown;

2. The bare FW base is prohibited from being powered on without load. The standard firmware is FWA-ECODR3-SMT-02VRS-MS, and it needs to be online burned by DriveTop software;

3. For high-frequency start-stop with large inertia load, it is recommended to connect a large-power braking resistor externally to avoid internal braking overheating faults;

4. The installation size is consistent with DKC1.1-040-7-FW, but the firmware cannot be used universally and the entire machine cannot be directly interchanged.
