II. Model Segmentation Explanation

DKS: DIAX02 platform low-power single-axis servo drive series (DKR as the main power spindle drive)

01.1: The first-generation DKS power architecture + unified enclosure, W030 full-power section installation size is universal and mechanically interchangeable

W030: W = internal natural convection cooling of the control cabinet; 30 = rated continuous output current 30A

B: Built-in Brake, the body integrates an internal brake chopping circuit + built-in brake resistor, no need for external braking power components

DL01: DLC bus control board: native SERCOSⅠ optical digital bus + local independent point programming, can operate independently of the upper CNC/PLC single-axis; compatible with analog, pulse dual external instructions, standard incremental encoder feedback

01: The first hardware revision, optimizing the bus shock resistance, SERCOS communication anti-interference, downward compatible with the initial 00 version

FW: Firmware, the side DSM slot is pre-installed with the original factory solidified firmware card, the driver automatically loads parameters when powered on, the entire machine replacement does not require firmware burning (models without FW suffix are empty slots, need to purchase firmware for writing separately)

III. Core Electrical Parameters

Main power supply: three-phase 3×230VAC ±10%, 50/60Hz; control auxiliary power: single-phase AC230V, control power consumption 85VA

Current specifications: rated continuous 30A, peak overload 62A, total machine capacity 4.5kVA, PWM carrier 18kHz

Applicable motors: MDD servo motor 1.5kW～7.5kW

DC bus: rated DC310V; built-in braking: peak discharge 7.2kW, continuous braking power 0.38kW

Environment: 0～+45℃ full load, the sealed cabinet's maximum temperature is 55℃, the rated power is reduced to 85% under overloading conditions; IP20 cabinet use, altitude ≤1000m full load

Form: L302×W86×H212mm, net weight 1.97kg

Protection: overcurrent, overvoltage, undervoltage, short circuit, overheating, encoder break line, stall hardware locking + fault passive alarm contact output

IV. Interface and Communication Configuration

Power terminals: three-phase incoming line, U/V/W motor power connection terminals, braking circuit built-in without external terminals

Low-speed control: 24VDC digital input/output, ±10V analog speed regulation, pulse positioning input terminals; independent aviation plug connects the motor encoder

Bus interface: dual SERCOS optical transceiver ports, multiple drivers are connected in series through optical cables for hand-to-hand networking, connected to the Festo CNC system multi-axis linkage

Auxiliary: fault NO/NC passive contacts, handheld debugging panel interface, DSM firmware slot (pre-installed FW firmware), bus maintenance test terminals

V. Product Function

Three modes switching: SERCOS bus digital control, analog voltage speed regulation, pulse point position positioning, the CNC system switches the instruction source as needed

DL01 board comes with point program storage, single-axis programmable indexing, reciprocating feeding, can operate independently of the upper controller

B built-in braking consumes the motor's regenerated energy, frequent start-stop suppresses bus overvoltage, eliminates overvoltage alarm

FW pre-installed solidified firmware, same model entire machine direct replacement, no parameter writing, no debugging, high maintenance and replacement efficiency

Modular plug-and-unplug main control, DL01 control board can be disassembled and replaced separately, reducing maintenance costs

VI. Application Scenarios

Imported vertical machining centers feed axis, multi-axis CNC lathes X/Z axis, high-precision printing indexing machine, multi-axis filling automation line, textile feeding equipment, original equipment from Europe and America major modification (SERCOS bus old system upgrade replacement)

VII. Maintenance Precautions Power outage maintenance: Standby for at least 15 minutes, fully discharge the high-voltage capacitors of the busbar before opening the cover for work.

Quarterly maintenance: Clean the dust in the aluminum shell heat dissipation slots, tighten the power terminals, check the dirtiness of the optical fiber connectors, inspect the aging of the encoder cables, and monitor the temperature rise of the built-in brake. Replace the entire machine if the power module is damaged, SERCOS frequently reports communication errors, the main control is burned out, or the brake overheats and trips.

Storage: Temperature-controlled and dry storage room, humidity ≤ 60%, protected from corrosive gases, and free from heavy pressure and impact.
