Model Explanation

DKC: ECODRIVE Digital Servo Power Unit

04: Communication version, factory standard equipped with PROFIBUS-DP bus (01 analog quantity, 02 SERCOS)

.3: Third-generation power hardware version

100: Rated continuous output current 100Ams

7: High-voltage model, DC bus nominal voltage 700VDC, compatible with three-phase 380~480V incoming line

FW: Empty base, without control motherboard, without fixed program, MGP main 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 55A; Independent DC24V control power supply, power consumption 38W

DC bus: Nominal 700VDC, overvoltage protection 850VDC, built-in high-power pre-charge circuit

Output specifications: Continuous rated 100A, short-time overload 240% for 400ms, carrier 4/8kHz selectable, maximum output frequency 1000Hz

Braking configuration: Built-in braking circuit with a continuous current of 6A and a peak current of 22A. For heavy-load frequent start-stop conditions, a large-power external external braking resistor must be externally connected

Dimensions: Width 105mm × Height 362mm × Depth 263mm, net weight 10.0kg, protection level IP20 (for cabinet installation)

Environmental conditions: Full-load operation at 0~45℃, altitude ≤ 1000m; Storage at -30℃ to +85℃, no condensation, no dust environment

Interface and communication configuration

Power terminals: Three-phase input L1/L2/L3, motor power terminals U/V/W, dedicated connection terminals for external braking resistors

Encoder aviation socket: Compatible with rotary transformers, TTL incremental ABZ, sine/cosine encoder feedback

Upper card slot: Compatible with MGP-7 high-voltage main control card, control card outputs DI/DO switch quantities, ±10V analog instructions, pulse direction point interface

Communication:

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

2. Body-fixed PROFIBUS-DP bus (fixed DP communication version 04, cannot be changed SERCOS)

3. Card slot can be optionally equipped with CANopen expansion sub-card Core function

The entire machine only has power drive hardware. The speed/position/torque closed-loop control is achieved through the MGP-7 main control board.

There are three control modes: ±10V analog speed regulation, pulse position control, PROFIBUS bus multi-axis synchronization. It supports electronic gears, soft limiters, origin reset, and联动 of motor braking.

Hardware full-loop protection： overcurrent， overvoltage， undervoltage， power module overheating， encoder break， output short-circuit faults self-lock and shutdown. Applicable scenarios

Large龙门 machining center feed axis, heavy-duty printing roller system drive, lithium battery coating machine main drive， large-load gantry mechanical hand， rubber extrusion machine precision main shaft.

Usage and Maintenance

1. The suffix 7 indicates high-voltage specification. It is strictly prohibited to connect to three-phase 220V industrial power supply. It is only allowed to be powered by AC 380~480V. Misconnection will directly cause power module breakdown.

2. The FW baseboard cannot be powered on and operated independently. It must be equipped with the same specification MGP-7 main control card + matching power firmware to be debugged and used.

3. For large inertia reciprocating heavy-load, it is necessary to select a large-power external braking resistor to avoid overheating and burning of the built-in braking circuit.

4. DKC04.3-100-7-FW and the abbreviated DKC4.3-100-7-FW spare parts can be seamlessly interchanged and used.
