DKS01.1-W050A-DG01-00 | Bosch Rexroth Indramat AC Servo Drive

Product Introduction The Bosch Rexroth (formerly Indramat) DKS series single-axis digital AC servo controller has a modular card-type structure. It is used in conjunction with the MDD series servo motors. The DG01 configuration comes with a built-in positioning command card + IO board, allowing for independent positioning operation or connection to PLC for upper-level control. It is mainly used for old models of machine tools, automated production lines, and packaging equipment.

Description

Model Segmentation Explanation

DKS01.1-W050A-DG01-00

DKS01.1: Product series, Model 1.1 body (without external energy storage capacitor, compact type), DKS01.2 supports external capacitor expansion

W050A: Power specification: Rated continuous 25A, Peak 50A, Three-phase AC230V input, Capacity approximately 9.5kVA; A is the hardware version code

DG01: Internal card configuration code: D = Digital Control, G = Standard DLC1.1 positioning main control card + DEA4.1 universal IO card, 01 is the card version number

00: Software firmware version, standard factory program, no customized modifications Technical Specifications

Input power: Three-phase 3×AC230V 50/60Hz, control power AC230V is independently powered

Current specifications: Continuous output 25A, short-term peak 50A, compatible with corresponding power MDD servo motors

Protection level: IP10 (installed in the control cabinet), DIN industrial standard specification

Braking: Built-in release braking unit, supports energy feedback energy consumption braking

Operating environment: 0~45℃, F-class humidity standard, industrial cabinet installation

Interface and communication configuration

CON1: Encoder feedback port (compatible with rotary encoders / incremental encoders, dedicated feedback for MDD motors)

CON2: Pulse command / analog command interface (differential pulse ±10V analog, PLC pulse control)

CON3: Debugging programming port (connected to Indramat debugging software, handheld operation panel)

DEA4.1 Onboard IO: 15 digital inputs, 16 digital outputs, directly connected to PLC analog signals, limit switches, start/stop signals

Communication: Standard parallel port / serial debugging, no standard bus, if Profibus is required, additional communication card is needed

Core functions

Three control modes: position closed-loop, speed closed-loop, torque closed-loop

DLC1.1 Main control card: Internal programmable point motion of the driver, can store multiple positioning programs, independent axis positioning without PLC

Built-in brake drive: Directly controls the start/stop and fault monitoring of the servo motor's electromagnetic brake

Full fault self-check: Overcurrent, overvoltage, overheating, encoder break, overload alarm code output

Programmable dynamic acceleration/deceleration, electronic gear synchronous control Applicable scenarios

Old-fashioned CNC machines, textile equipment, injection molding auxiliary machinery, automated conveying lines, imported original equipment spare parts for repair and replacement, main drive models of the Indramat system from Europe and America.

Operation and maintenance instructions

Installation: Only vertical installation inside the electrical control cabinet, reserve space for up and down heat dissipation, prohibit bare installation in dusty and humid environments

Commissioning: Need to upload parameters and firmware using the Indramat DSM software, match the corresponding MDD motor nameplate parameters

Spare parts: original factory new machines are out of production, the market mainly consists of refurbished parts from disassembled machines; High failure points: power board, encoder interface, IO board

Cabling: Power cables and encoder cables should be routed separately to reduce interference, brake resistors should be externally connected and expanded as needed
