Model Explanation

DKC: ECODRIVE Series Digital Servo Power Unit

04: Bus Type Code. The body integrates PROFIBUS-DP hardware, different from 01 for analog and 02 for SERCOS bus type.

.3: Third-generation power hardware optimization version

040: Rated Continuous Output Current 40Amps

7: High Voltage Specification, three-phase 380~480V input, DC bus nominal 700VDC

FW: Empty Power Base, without MGP Main Control Card, without fixed program. Control card and firmware need to be selected and burned separately. Technical Specifications

Main power supply: Three-phase AC380~480V ± 10%, 50/60Hz, maximum input current for the entire machine is 16A; independent DC24V control power supply, power consumption 21W

DC bus: Rated 700VDC, overvoltage protection 850VDC, built-in 24Ω pre-charge soft-start resistor

Output specifications: Continuous 40Arms, short-term 240% overload output, maximum output frequency 1000Hz, carrier 4/8kHz selectable

Braking parameters: Built-in braking circuit rated DC2A, short-term peak 10A, heavy-load conditions require external external braking resistor

Dimensions: Width 65mm × Height 360mm × Depth 261mm, net weight 5.7kg, IP20 cabinet installation, built-in axial flow cooling fan

Environment: 0~45℃ full-load operation, altitude ≤ 1000m, overload power reduction; storage - 30~+85℃

Compatible motors: MKD07/08, MAC07/08 series, power range 8~12kW

Interface and communication configuration

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

Encoder aviation socket: compatible with resolver, TTL incremental ABZ, sine-cosine encoder feedback

Upper card slot: compatible with MGP-7 high-voltage main control board, control card leads DI/DO digital quantities, ±10V analog instructions, pulse direction point interface

Communication interface

1. RS232 debugging port (enable MGP card): IndraWorks parameter debugging, firmware download and burning

2. Standard on-board PROFIBUS-DP bus interface, version 04 fixed DP communication, does not support SERCOS

3. Card slot can be selected to expand CANopen sub-card Core function

The entire machine only has the power inverter hardware. All position/velocity/torque control logic is implemented by the MGP control card.

Control mode: ±10V analog speed regulation, pulse position control, PROFIBUS bus multi-axis synchronization in one package, supporting electronic gear, origin return to zero, and motor brake timing control.

Full hardware protection: overcurrent, overvoltage, undervoltage, module overheating, encoder break, output short-circuit faults self-lock and shutdown. Applicable scenarios

Numerical control machining center feed axis, food and pharmaceutical packaging equipment, printing roller system drive, small and medium-sized automated gantry mechanical hand, lithium battery equipment precision positioning axis.

Usage and Maintenance

1.-7 The high-pressure base is prohibited from being connected to a three-phase 220V power supply. It is only allowed to be powered by AC380~480V. Misconnection will directly damage the power module.

2. The FW bare base cannot be powered on and operated independently. It must be equipped with a matching specification MGP-7 main control card + corresponding power firmware.

3. For high-frequency start-stop and large inertia loads, external high-power braking resistors must be installed to avoid overload damage to the built-in braking circuit.

4. It is not allowed to directly replace across current models (020/100A). The IGBT and bus hardware parameters are not compatible.
