2. Model Interpretation

DKS: Compact low-power single-axis servo drive series based on the Indramat DIAX02 platform, compatible with MDD servo motors. DKR is the high-power spindle drive series.

01: The first-generation DKS hardware power supply architecture.

.1: The first-generation unified enclosure structure, with installation dimensions and holes that are universal for the full power range model W030, and mechanical interchangeability is compatible.

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

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

DL01: DLC bus positioning control board: native SERCOS I optical digital bus interface + local single-axis programmable point position control, compatible with ±10V analog input + pulse command dual external setting, standard configuration of incremental encoder feedback, can independently write motion programs and operate independently without the upper controller

01: The first hardware revision, optimizing the bus circuit and SERCOS communication anti-interference, downward compatible with the original hardware version 00

No FW: Does not come with factory-固化 firmware card， after purchase， it is necessary to match the corresponding version firmware program for writing into the driver

4. Interface and Communication Configuration

1. Power terminals： three-phase incoming line， U/V/W motor power line screw fastening terminals， base engraved U/V/W phase sequence marking， brake circuit integrated internally， no external braking terminals；

2. Control terminals： 24VDC universal analog input/output， ±10V analog speed command， pulse positioning input terminals； independent aviation socket for connecting motor incremental encoder cables；

3. Bus interface： standard SERCOS optical transceiver interface on the body side， supports multi-drive fiber serial networking， connects to the Festo CNC system multi-axis bus control；

4. Auxiliary contacts： passive NO/NC fault alarm contacts， connected to PLC fault interlock；

5. Expansion slot： DSM firmware slot empty (no FW)， universal interface for handheld debugging panel， bus maintenance and testing terminals retained.

5. Core Functions

Three control modes： SERCOS bus digital command control， ±10V analog speed regulation， pulse point position positioning， one-click switch control source；

2. DL01 board comes with independent motion programming， can store point program for a single axis， can independently complete reciprocating， indexing， and fixed-length feeding actions without CNC/PLC. 3. The B-type built-in braking circuit consumes the electrical energy regenerated by the motor, stabilizes the DC bus, and suppresses overvoltage alarms during frequent start-up conditions;

4. The 01 version of the hardware optimizes the SERCOS bus's anti-interference performance. When using multi-axis fiber networking, the failure rate of communication disconnections is lower than that of the 00 version;

5. Real-time hardware fault detection. In case of a fault, the IGBT power output is immediately blocked, and the fault signal is synchronously output by the passive contacts;

6. The main control board adopts a modular plug-and-play design. The DL01 control board can be disassembled and replaced separately, reducing the downtime for maintenance;

6. Application scenarios

Imported multi-axis feed systems for machining centers, full-digital CNC lathes X/Z axes, multi-axis联动 filling production lines， high-precision printing indexing equipment， multi-servo textile machinery， replacement for major repairs of original equipment automation machines from Europe and America， compatible with the SERCOS bus architecture for retrofitting older Yaskawa CNC systems.

7. Operating and maintenance instructions

1. Power-off maintenance requires a static period of at least 15 minutes. After the high-voltage capacitor of the bus is completely discharged， open the cover for work to prevent electric shock；

2. Quarterly maintenance： Clean the dust in the aluminum slots of the housing， tighten the power terminals， check the dirtiness of the fiber optic connectors， the aging of the encoder cables， and the temperature rise of the built-in braking resistors；

3. Fault replacement determination： Replace the entire machine when the power module is damaged， SERCOS communication frequently reports errors， the DL01 main control is burned out， or the built-in braking overheats and trips；

4. Storage environment： A constant temperature and dry storage room， with an environmental humidity of ≤60%， away from corrosive gases， intense vibrations， and prohibited from heavy pressure stacking storage.
