Technical Specifications

Main Input Power: 3-phase AC200~230V ±10%, 50/60Hz; optional single-phase AC230V auxiliary control power supply independent from main circuit

DC Bus Rated Voltage: 300VDC; built-in dynamic braking module, continuous braking power 0.3kW, peak braking power 5kW, supports external braking resistor wiring expansion

PWM Switching Frequency: Fixed 4kHz

Protection Rating: IP10, vertical cabinet mounting only, natural convection cooling without built-in fan

Ambient Working Condition: Full-load running at 0℃~+45℃; 5%~85%RH non-condensing; output derating required when installation altitude over 1000m, max ambient +55℃ with full load derating

Dimension & Net Weight: 262×355×60mm, approx 10.8kg

Built-in multi-protection logic: overvoltage/undervoltage, mains phase loss, IGBT overcurrent, power module overtemperature, encoder line breakage; drive cuts off power output and triggers fault alarm upon abnormal signals

Interface & Communication Configuration

CON1 (25pin D-SUB): Exclusive feedback port for Indramat proprietary DSF digital encoder or resolver signal acquisition, incompatible with standard incremental encoder directly

CON3 (9pin D-SUB RS232): Service debugging port, connects with Indramat DSM PC commission software for parameter backup, motor auto-tuning, fault log reading and firmware upgrading

Main Terminal Block: Terminals for 3-phase mains input, U/V/W motor power output and external brake resistor connection

Internal single plug-in slot for interchangeable control board:

DA card: ±10V analog speed/torque command input + onboard analog I/O terminals

DL card: Pulse+Direction positioning command input + digital I/O for limit switch and equipment interlock signal

DS card: SERCOS optical fiber bus communication for multi-axis synchronous linkage control

Core Functions

Bare D-type base only implements power inversion, DC bus management and encoder signal sampling; complete triple closed-loop control (current/speed/position) needs matching DA/DL/DS plug-in control card installed

Pre-FW equipped unit stores motor parameter, motion setting data and historical fault records inside onboard firmware chip

Reserved internal motor holding brake control circuit; brake release/lock logic programmable via drive parameter configuration

No expandable external DC bus capacitor interface, not applicable for ultra-frequent short-cycle start-stop heavy-duty working conditions (core difference vs DKS01.2 model)

Programmable fault response mode to set customized protection actions for different abnormal alarms

Application Fields

Spare replacement and axis renovation for legacy European textile warp knitting machines, rotary printing presses, small CNC cutting equipment, plastic extrusion machinery and old automatic assembling production lines originally configured with Indramat DIAX02 servo system

Operation & Maintenance Instructions

Reserve minimum 80mm upper and lower ventilation clearance inside electrical cabinet for heat dissipation; separate shielded encoder cables and high-current power cables in different wiring ducts to reduce EMI interference

DKS01.1 power base cannot be directly replaced with DKS01.2 due to internal DC bus circuit structural difference

Periodic maintenance: Clean cabinet dust every 6 months, fasten all power terminal screws and inspect shielding integrity of DSF feedback cables; vulnerable spare parts include internal auxiliary switching power supply, CON1 connector socket and main IGBT power module
