Encoder interface: Compatible with rotary transformers, TTL incremental ABZ, Sin/Cos full series of encoder feedback

Slot configuration: Built-in dedicated slot for MGP-7 main control board, control board leads DI/DO switch quantity, ±10V analog instructions, pulse direction point interface

Communication ports

1. RS232 debugging serial port (enable MGP board): IndraWorks parameter debugging, firmware burning and upgrading

2. X60 terminal native DeviceNet bus interface (06 series fixed DeviceNet protocol), optional DKC06.3-LK-DVN01 communication expansion card to optimize bus stability

3. Optional additional sub-card to expand RS485 communication Core function

The main body only includes inverter power hardware. The entire position/velocity/torque three-loop closed-loop control is achieved through the MGP-7 main control card and the accompanying firmware;

Supports ±10V analog speed control, pulse position control, DeviceNet bus multi-axis electronic gear synchronization, origin return to zero, and linkage with motor brake timing;

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

Numerical control machining center feed axis, high-speed carton packaging main drive, wide-format rotary printing machine auxiliary shaft, automated transplanting mechanical hand, lithium battery cutting equipment driven servo.

Usage and Maintenance

1. Models with suffix 1.7 that use high-voltage power supply must not be connected to a three-phase AC220V power grid. Only AC380~480V power supply is allowed. Incorrect connection will directly damage the power module;

2. The FW bare base cannot be powered on independently. It must be matched with the same power MGP-7 main control card + corresponding power firmware to be debugged and operated;

3. For high-frequency start-stop loads with large inertia, an external large-power braking resistor must be installed to avoid overheating and damage of the built-in braking circuit;

4. DKC06 (DeviceNet), DKC05 (CANopen), and DKC04 (PROFIBUS) have similar installation dimensions, but the bus hardware is incompatible. It is not possible to directly replace spare parts across series.
