DKS01.1-W100A｜Rexroth Indramat DIAX02 Servo Drive
Product Overview
Compact single-axis digital servo drive from former Indramat(Rexroth), DKS01.1 series, W100A power rating. Matches MDD/MKD synchronous servo motors, widely used as spare part for obsolete European CNC, printing and textile machinery, original production discontinued, stock mainly used/refurbished units.
Description
Model Code Definition
DKS01.1：Compact main unit of DIAX02 family, no external DC bus capacitor mounting interface, cabinet vertical mounting design
W100A：Power specification, 3-phase AC230V input; continuous output 50A, peak 100A, approx.19kVA; A = power PCB hardware revision
Suffix control card codes (DL/DG/RL/R-UL) are separate behind W100A, same card classification rules as previous W050A
Technical Specifications
Main supply: 3×AC200~230V 50/60Hz, independent AC230V control power supplyContinuous output:50A, peak short-time 100ABuilt-in dynamic braking circuit, allows external high-power brake resistor extensionProtection class IP10, indoor cabinet installation onlyOperating ambient:0~45℃, 5%~85%RH non-condensing, default PWM carrier 4kHz
Interface & Communication Configuration
CON1: Motor encoder feedback port, supports resolver / incremental encoder for MDD/MKD series motorsCON2: Function determined by postfix control board:DL=Pulse+±10V analog command; DG=Onboard positioning+integrated I/O; RL/R=Sercos fiber bus onlyCON3: RS232 service port for DSM commissioning software / handheld programmer for parameter setup & fault diagnosisNo standard onboard I/O on DL/RL version; DG variant equipped with built-in digital input/output terminals.
Core Functions
Three closed-loop control modes: Position / Speed / Torque controlBuilt-in brake output circuit for motor holding brake auto management under enable/fault statusFull diagnostic alarm: Overvoltage/Undervoltage/Overcurrent/Overtemp/Encoder loss/Bus communication faultElectronic gear ratio, acceleration/deceleration curves configurable via DSM software or master controller.
Application Scope
Old imported machining centers, rotary printing machines, multi-axis textile production lines, custom European automated equipment maintenance replacement.
Operation & Maintenance Notes
Mount vertically inside electrical cabinet with ≥5cm upper/lower cooling clearance; separate routing for power cable, shielded encoder wire and fiber optic cableCommissioning requires Indramat DSM software to load motor parameters and match upper control setupCommon failure points: Power IGBT module, CON1 encoder socket, internal auxiliary power circuitSpare replacement: W100A power base compatible swap among DL/DG/RL/R control cards after corresponding card replacement and parameter downloading, cannot cross replace with W050A directly due to different power rating.
