2. Model Interpretation

DKS: Indramat compact small-power single-axis servo drive series, DIAX02 platform, different from the high-power DKR spindle drive

01: The first-generation DKS hardware architecture platform

.1: The initial unified enclosure, with the same installation dimensions and hole openings as the W030 power derivative products, mechanical interchangeability and compatibility

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

B: Built-in Brake, built-in built-in braking chopper + built-in braking resistor, no need for external braking components

DA01: Control board code 01, analog control board: ±10V speed analog instruction + incremental encoder feedback, general switch quantity IO, no SERCOS optical fiber bus

01: Hardware revision 1st generation, optimizing power supply circuit, main control PCB wiring, compared with the 00 initial version, the power supply ripple defect is repaired, electrical downward compatibility with the 00 version

FW: Firmware, the body is pre-installed with a fixed program module, the drive is directly loaded with factory motion parameters when powered on, bare machines without FW suffix models need to purchase firmware for burning separately

3. Technical Parameters

Auxiliary control power: single-phase AC230V, control power consumption 85VA;

Rated continuous output current: 30A, peak overload current 62A;

Applicable MDD servo motor power: 1.5kW to 7.5kW;

DC bus rated voltage: DC310V;

Brake specification: built-in brake, peak discharge 7.2kW, continuous discharge 0.38kW;

Operating environment: 0℃ to +45℃ full power, cabinet sealed, maximum + 55℃, reduction to 85% for over 1000m altitude;

Protection level: IP20 (only for use in the control cabinet);

Altitude: ≤1000m full load, >1000m step reduction of power;

Cooling: full aluminum enclosure natural heat dissipation without fan;

Overall size: L302mm×W86mm×H212mm, net weight 1.98kg;

Protection functions: overcurrent, overvoltage, undervoltage, bus short circuit, overheating, encoder break line, motor locked rotor hardware locking protection.

4. Interface and Communication Configuration

Main circuit three-phase incoming line, U/V/W motor power line screw terminal, base marking phase sequence; Brake circuit integrated in the body, no external braking connection terminal;

Zone terminals: 24VDC switch quantity IO terminals, ±10V analog instruction terminals, pulse positioning input terminals; Independent aviation plug connects the motor incremental encoder;

Side passive NO/NC fault alarm contacts, used for联动PLC alarm； No native SERCOS， RS485 bus， DA01 board card does not support bus expansion；

Front of the body DSM card slot pre-installed FW firmware module， reserved handheld debugging panel interface， side reserved bus maintenance and testing terminals.

5. Core Functions

1. Receive CNC/PLC analog voltage， pulse signals， achieve precise control of position/velocity/torque for MDD servo motor；

2. Shutdown， deceleration power generation feedback is consumed by the built-in B-type braking circuit to consume regenerated electrical energy， stabilize bus voltage， prevent IGBT overvoltage damage；

3. 01 revision hardware optimizes suppression of instantaneous large current impact， stability of frequent start-stop conditions is better than the 00 original version；

4. FW pre-installed fixed firmware， factory parameters are permanently stored， same model drives can be directly replaced by the entire machine， no debugging burning required； 5. Real-time fault detection, abnormal power output is immediately blocked, and the passive contacts synchronously output the fault signal;

6. Modular plug-and-unplug the main control board, the DA01 board can be disassembled and replaced separately, reducing maintenance costs.

6. Application scenarios

Small CNC lathes X/Z feed axes, vertical machining centers auxiliary feed axes, filling packaging servo positioning, textile feeding servo, small injection molding machines servo, printing indexing equipment; mostly used for major repairs of imported old equipment in Europe, technical renovation of automated production lines, and replacement of spare parts for discontinued Rexroth models.

7. Operating and maintenance instructions

1. After power-off for maintenance, stand still for **≥15 minutes**, fully discharge the bus capacitor before opening the cover to prevent high-voltage electric shock;

2. Quarterly maintenance: clean the dust in the aluminum profile heat dissipation slots, tighten the power terminals, check the aging of the encoder cables and the temperature rise of the built-in braking resistors;

3. Replacement conditions: power module breakdown, DA01 main control burned out, frequent overheating of the built-in braking causing trip, FW firmware error and inability to power on, then replace the entire machine;

4. Storage: store in a constant temperature and dry warehouse, humidity ≤ 60%, avoid corrosive gases and intense vibration, prohibit heavy pressure stacking.
