Model Explanation

DKC: ECODRIVE Digital Servo Power 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 model

FW: No original factory pre-installed firmware, bare power hardware base, firmware needs to be burned separately later Technical Specifications

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

DC bus: Nominal 700VDC, braking start threshold 820VDC, built-in pre-charging and integrated braking power loop

Output performance: 40A continuous rated, 230% short-term overload 350ms, PWM carrier 8kHz, maximum output frequency 1200Hz

Heat dissipation: Built-in axial fan for forced air cooling, total machine net weight 4.4kg, dimensions W65×H360×D210mm, IP20 cabinet protection

Environmental conditions: Full-load operation at 0~45℃, altitude ≤ 1000m; storage - 25~+80℃, environmental 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: Compatible with TTL incremental ABZ, rotary transformer, HIPERFACE/EnDat absolute value encoder, comes with encoder power output

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

Communication ports

1. RS232 debugging serial port: Only used for DriveTop firmware download and parameter debugging, communication function takes effect after firmware is installed

2. Native non-bus interface, CANopen/Profibus bus requires installation of independent expansion card Core function

The hardware only retains the power inverter circuit and peripheral wiring. The three-loop servo control and point position logic are all implemented by flashing the ASE firmware;

After the corresponding firmware is loaded, it supports three operation modes: ±10V analog speed regulation, pulse direction point position, and I/O triggering of 32 internal program positioning;

The hardware is equipped with full-loop protection: IGBT short circuit, output overcurrent, bus over/under voltage, module over-temperature, encoder broken wire fault locking, and dual digital tube fault code display on the panel. Applicable scenarios

Printing machinery drum drive, heavy-duty packaging feed shaft, medium and small-sized CNC machines, fully automatic winding/cutting equipment, customized transplant automation production line spare parts modification.

Usage and Maintenance

1. The suffix 1.7 high-voltage base must not be connected to single-phase AC220V power supply; incorrect connection will directly damage the power module;

2. The bare FW base cannot be powered on without firmware; the standard firmware model is FWA-ECODRV-ASE-04VRS-MS, and the program must be burned online using 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 the built-in braking overheating alarm;

4. The installation dimensions are exactly the same as DKC1.1-040-7 (the entire machine pre-installed firmware version), but the firmware is not universal and cannot be directly interchanged with the entire machine.
