DKS01.1-W030B-RS01-03 | Rexroth Indramat DIAX02 SERCOS + Specialized Resolver Servo Drive

1. Model Explanation in Detail DKS01.1-W030B-RS01-03 DKS01.1: DIAX02 first-generation compact single-axis servo base, power housing universal W030: Natural air cooling inside the cabinet, continuous rated 30A, peak 62A, suitable for MDD 1.5 - 7.5kW servo motors B: Built-in Brake, built-in braking chopper + built-in braking resistor, no need for external braking unit RS01 (core control board) RS = Resolver + SERCOS dedicated board: Native compatibility with resolver (Resolver) motor feedback (different from RL incremental encoder), standard SERCOS I fiber bus networking Retain ±10V analog instructions, pulse direction input, programmable DI/DO switch quantities No RL series encoder pulse simulation output, specially designed for resolver feedback models 03: Firmware version code V03, DSM firmware card slot pre-installed with V03 version firmware (comes with FW, no need to separately program); suffix number = built-in firmware version number (00 empty slot without firmware, 01/02/03 corresponding to different firmware versions) Quick distinction of control board DA: Pure ±10V analog, no SERCOS; DL: SERCOS + single-point programming; RL: SERCOS + incremental encoder + pulse replication; RS: SERCOS + resolver-specific (this model)

Description

II. Electrical Parameters (W030 Power Unification)

Main Power Supply: Three-phase AC 230V ± 10% 50/60Hz; Control Auxiliary Power AC 230V

DC Bus: DC 310V, PWM Carrier 18kHz; Built-in Braking Peak 7.2kW, Continuous 0.38kW

Dimensions: 302×86×212mm, Net Weight 1.97kg, IP20 Cabinet Installation

Environment: 0~45℃ Full Load, Enclosed Cabinet 55℃ Power Reduction 85%

III. Unique Features of RS01 Board

Native Rotating Transformer Signal Demodulation: Directly connected to MDD Rotating Transformer Motor, no need for external Rotating Transformer to Encoder Module, resistant to oil contamination, high temperature, and dust (optimal for harsh environments of machine tools)

Dual SERCOS Optical Ports, Multi-axis Hand-to-Hand Optical Networking for Interface with Yaskawa MTX/Indramat CNC System

Multiple Programmable I/O: Origin, Positive and Negative Hard Limiting, Fault Interlock Input and Output

Support for Three Control Sources: SERCOS Bus, ±10V Analog Speed Control, Pulse + Direction Positioning

IV. Key Notes for 03 Suffix

-03 = Factory Pre-installed V03 Version Firmware (Self-contained FW), Power-on and Run Directly, No Software Firmware Flashing Required; Replace the Same Model RS01-03 with the Same RS01-03 Can be Directly Interchangeable

RS01-00: Empty Card Slot No Firmware; RS01-01/02/03 Upgrade Firmware Versions Sequentially, Firmware Downward Compatibility with Hardware

V. Applicable Scenarios

Old Western-style CNC Lathes, Grinding Machines, Forging Equipment, Metallurgical Conveyor Equipment (Equipment with Motor Feedback from Rotating Transformer is Exclusive, Incremental Encoder Motors Select RL Series)

VI. Replacement Precautions

Same W030 Base: RS01 Can Directly Replace RL/DL/DA Boards, but Must Match Motor Feedback (Rotating Transformer Use RS, Incremental Encoder Use RL)

03 Firmware Model Prioritize Replacement for Original Equipment RS01-03, Cross-Version 01/02 Need to Verify Motor Parameters for Firmware Compatibility
