Environmental conditions: Full-load operation at 0~45℃, Altitude ≤1000m; Storage - 30~+85℃, Environmental humidity < 95% without condensation

Interface and communication configuration

Power terminals: L1/L2/L3 three-phase power supply inlet, U/V/W motor power connection, Special connection terminals for external braking resistors

Encoder interface: Fully compatible with rotary transformers, TTL incremental ABZ, Sin/Cos sine/cosine encoder feedback

Slot positions: Special plug-in MGP-7 series main control board, Control board outputs DI/DO digital quantities, ±10V analog instructions, Pulse direction point interface

Communication ports

1. RS232 debugging serial port (enable MGP board assembly): IndraWorks parameter debugging, firmware download and upgrade

2. Integrated native PROFIBUS-DP bus (04 version hardware fixed DP protocol, cannot be changed to SERCOS)

3. Card slots can be optionally equipped with CANopen, InterBus expansion sub-boards to expand bus types Core function

The main body only includes inverter power hardware. The entire position/velocity/torque three-loop closed-loop control is achieved by relying on the MGP-7 main control card.

It supports ±10V analog speed control, pulse positioning control, PROFIBUS bus multi-axis electronic gear synchronization, origin search, and linkage with motor brake timing.

Integrated hardware full protection: power transistor short circuit, output overcurrent, bus over/under voltage, module over-temperature, encoder break wire fault self-lock shutdown. Applicable scenarios

Heavy-duty gantry milling machine main feed axis, plastic extruder main drive, large-scale lithium battery coating/slicing main transmission, heavy-duty gantry mechanical hand main servo, wide-format printing equipment main roller drive.

Usage and Maintenance

1. Models with suffix 1.7 are prohibited from being connected to AC220V three-phase power supply. Only AC380~480V power supply is allowed. Incorrect connection will directly damage the IGBT power module;

2. The FW bare base cannot be powered on independently. It must be matched with the MGP-7 main control card of the same power segment + corresponding firmware for debugging;

3. Frequent start-stop of large inertia loads must be equipped with an external high-power braking resistor to prevent the built-in braking circuit from overloading and burning out;

4. The abbreviated model DKC043 is fully compatible with the standard model DKC04.3 in terms of mechanical and electrical aspects. On-site spare parts can be directly interchanged.
