The bare power base has no control logic. The entire machine's functions are determined by the optional control board.

SGP Control Card: Pure SERCOS optical fiber bus closed-loop positioning control, dedicated for multi-axis linkage on the bus.

MGP Control Card: ±10V analog speed regulation + pulse position + SERCOS bus three-in-one control, integrating electronic gear, origin search, motor brake timing control; integrating full hardware fault protection such as overcurrent, overvoltage, undervoltage, overheating, encoder break, and input phase missing. Applicable scenarios

Main drive of large plastic extruders, main spindle of heavy-duty gantry boring and milling machines, main drive of papermaking, main forging forming machine, main servo drive of large-capacity spinning equipment for chemical fibers

Usage and maintenance

Suffix 7: High-pressure specification prohibits single-phase AC220V power-on, only suitable for three-phase 380V industrial power supply

FW bare base cannot be powered on for individual debugging, it must be equipped with MGP/SGP main control card + corresponding version VRS firmware

DKC02.3: The hardware of the full-power range (020/030/040/100/200) MGP/SGP control card is universal, spare parts replacement should first check the original equipment firmware version

For heavy-load conditions with frequent start-stop and energy feedback, a large-power braking resistor must be externally installed to avoid overheating and damage caused by the built-in discharge loop
