Interface and communication configuration

Power terminals: L1/L2/L3 three-phase incoming lines, U/V/W motor power terminals, External braking resistor connection position

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

Slot configuration: Special slot for MGP-7 main control board insertion, Control board outputs DI/DO switch quantities, ±10V analog instructions, Pulse direction point interface

Communication ports

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

2. Standard on-board native CANopen bus (fixed CANopen protocol for 05 version type, optional expansion card for DP/InterBus)

3. Optional DKC05.3-LK-CAN01 expansion card to optimize CAN communication performance Core function

The main body only includes inverter power hardware. The position/velocity/torque three-loop closed-loop control is all realized by the MGP-7 main control card and corresponding firmware;

Support ±10V analog speed regulation, pulse position control, CANopen bus multi-axis electronic gear synchronization, origin return to zero, motor brake linkage control;

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

Numerical control grinding machine feed axis, main and slave drive of high-speed packaging machine, small extrusion auxiliary machine, lithium battery cutting low-power driven shaft, servo of automated transplanting mechanical hand.

Usage and Maintenance

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

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

3. For large inertia loads that frequently start and stop, an external braking resistor must be installed to prevent the built-in braking circuit from overloading and being damaged;

4. The hardware installation dimensions of the DKC05 series and DKC04 series are similar, but the bus protocol is different. It is not possible to directly interchange spare parts across series.
