2. Technical Specifications

Main Power Supply: 3-phase AC230V ±10%, 50/60Hz; independent single-phase AC230V auxiliary control power supply

DC Bus: Rated 300VDC; built-in dynamic braking circuit, 0.5kW continuous braking power, 18kW peak braking capacity, supports external high-power braking resistor expansion

PWM Switching Frequency: 4kHz

Protection Class: IP10 (cabinet-only vertical installation)

Ambient Working Condition: 0℃~+45℃ full-load operation; ambient humidity 5%~85% non-condensing; load derating when installation altitude over 1000m

Cooling Mode: Natural convection air cooling inside control cabinet

Dimension & Weight: 265×360×62mm, approx.11.2kg

3. Interface & Communication Configuration

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

Terminal Block for Main Circuit: 3-phase mains input terminals, U/V/W motor power terminals, external braking resistor wiring terminals

Control Card I/O Terminal (from DL01 card): 15 digital inputs /16 digital outputs for external sensor, limit switch and interlock signal connection

CON3 Debug Port: RS232 serial port, connects with Indramat DSM PC commissioning software for parameter backup, motor identification, fault diagnosis and firmware update

Command Input Terminal (DL onboard): AB-phase pulse + direction signal input port for external PLC pulse positioning instruction

4. Core Functions

Full closed-loop three-loop control (position/speed/current) via onboard DL01 positioning card, receives external pulse command to complete single-axis precise point-to-point positioning, indexing and intermittent motion control

Integrated full protection logic: overvoltage/undervoltage, input phase loss, IGBT overcurrent, power module overtemperature, encoder wire breakage; drive locks output and triggers fault alarm once abnormal detected

Reserved built-in motor holding brake control loop, brake ON/OFF logic programmable via drive parameter setting

Optimized DC bus circuit of DKS01.2 hardware, allows external bus capacitor assembly to adapt frequent start-stop short-cycle working load

Preinstalled FW firmware enables parameter storage, motion program editing and fault record storage inside controller

5. Application Fields

Spare replacement for obsolete European-made textile warp knitting machine, rotary printing equipment, German CNC cutting machinery, multi-axis extrusion production line and automatic assembly equipment; used for old servo system maintenance and partial axis motion renovation on original Indramat DIAX02 automation lines

6. Operation & Maintenance Guidelines

Mount vertically inside electrical cabinet, reserve ≥80mm upper/lower ventilation clearance for heat dissipation; separate power cable and feedback shield cable in different wiring trunking to reduce electromagnetic interference

DL01 configured drive cannot be replaced with DA (analog) /DS (SERCOS bus) card base unit directly due to internal control circuit difference

Routine maintenance: Clean internal cabinet dust every half year, fasten all power wiring terminals, inspect shielding integrity of DSF encoder cables

Common wearable parts: Main power IGBT module, CON1 encoder socket, internal auxiliary switching power supply module
