Model Explanation

DKC: ECODRIVE Digital Servo Amplifier Series

1.1 = 01.1: The first generation ECODRIVE01 hardware platform

040: Rated continuous output current 40Amps

7: 700VDC high-voltage bus, three-phase AC380-480V power supply specification (3 represents a 220V low-voltage model)

No FW: Built-in original firmware, complete unit, no need to separately program Technical Specifications

Main power supply: Three-phase AC380～480V ±10%, 50/60Hz, incoming line rated 32A; Independent DC24V auxiliary control power supply (0.7A)

DC bus: Nominal DC700V, overvoltage protection 820V, built-in pre-charging and integrated energy braking circuit

Output performance: Continuous rated 40A, overload 230% for 350ms, carrier 8kHz, maximum output frequency 1200Hz

Heat dissipation: Built-in axial fan for forced air cooling, total power consumption approximately 180W

Dimensions: Width 65mm × Height 360mm × Depth 210mm, net weight 4.4kg, IP20 cabinet protection

Environmental conditions: Full-load operation at 0～45℃, 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 terminals, built-in braking resistor connection terminals

Encoder interface: Compatible with TTL incremental ABZ, resolver, HIPERFACE/EnDat absolute value encoders, with built-in encoder power output

Control terminals: Green plug-in terminals DI/DO limit, origin, enable, motor brake timing, ±10V analog instructions, pulse direction input

Communication ports

1. RS232 debugging serial port: DRIVETOP software parameter reading and writing, motor parameter identification

2. Standard I/O points interface, driver internally stores 32 independent positioning programs

3. Native without fieldbus, CANopen/Profibus require additional communication sub-card Core function

The entire machine is equipped with a three-ring closed-loop control firmware. There are three control modes: ±10V analog speed regulation, pulse/direction point position control, and I/O triggering of internal program positioning;

It comes with hardware soft limiters, hardware positive/negative limits, automatic zero return, and linkage sequence of brake;

Hardware full protection: IGBT short circuit, output overcurrent, bus over/under voltage, module over-temperature, encoder broken wire fault shutdown; dual digital tubes on the panel display fault codes, making maintenance convenient. Applicable scenarios

Heavy-duty vertical packaging main feed, printing equipment drum drive, feed axis for small and medium-sized CNC machines, fully automatic winding machine, non-standard automated transplant equipment.

Usage and Maintenance

1. Models with suffix 1.7 only allow connection to three-phase AC380V. It is strictly prohibited to connect to single-phase 220V power grid. Incorrect connection will cause power module breakdown;

2. The entire machine comes with firmware. When replacing different power motors, DriveTop must be used to re-identify the motor parameters;

3. Frequent start-stop of large inertia loads. It is recommended to connect a large power braking resistor externally to avoid overheating alarm of the built-in braking;

4. DKC1.1-040-7 (complete machine) and DKC1.1-040-7-FW (empty base) have the same installation dimensions. However, the FW model has no firmware and cannot be directly powered on for interchange.
