Model Explanation

DDC1.1: DDC series, hardware V1.1, IP65 air-cooled platform

K100A: K = natural cooling; continuous / peak 100A; A = standard noise

DS50: D = digital encoder feedback; S = SERCOS optical bus interface; 50 = SERCOS standard communication version

01: Function code 01 = full version; includes factory pre-installed firmware (ready to use upon power-on)

Basic Parameters (K100A Platform)

Input: Three-phase AC 380–480V ± 10%, 50/60Hz, 15kVA

Continuous output: 100A; Peak 100A

Power: Continuous 4.5kW; Peak 9kW

PWM carrier: 4kHz

Braking: Built-in regenerative braking, peak 20kW, continuous 0.5kW

Protection: IP65 (dust-proof, oil mist-proof)

Temperature: +5°C to +45°C (rated), maximum + 55°C (derated)

Weight / Size: Approximately 24kg; 550×180×320mm

Altitude: ≤ 1000m  No reduction factor

Interface and Communication

Motor feedback: Digital encoder (compatible with MDD/MKD100A series)

Control interface: SERCOS-III optical bus (DS50), high-speed real-time communication

Debug port: RS232 (DDS2PC/Motion Manager software)

I/O: 15DI/16DO (24VDC, limit / enable / alarm)

Expansion slot: U1–U3 (optional fieldbus card, such as Profibus, Interbus)

Core functions (DS50-01 SERCOS bus version)

SERCOS optical bus control: Multi-axis synchronization, high-speed position / speed / torque commands, real-time closed-loop

Three closed-loop: Position / speed / torque control (bus commands)

Bus characteristics: Optical transmission, strong anti-interference, short cycle (≤ 1ms), multi-axis linkage

Diagnosis: Overcurrent / overvoltage / overheating / short circuit / phase loss protection

Power-off parameter retention, built-in regenerative braking

Includes firmware direct operation, no need to purchase firmware module separately

Comparison with DS series bus versions

DS50-00: SERCOS bus, digital feedback, no firmware, basic communication

DS50-01: SERCOS bus, digital feedback, with firmware, ready to use upon power-on

DS51-01: SERCOS enhanced version, digital feedback, with firmware, optimized multi-axis synchronization Application scenario

Multi-axis linkage of machine tools (such as machining centers, lathes, milling machines, SERCOS bus PLC)

High-speed synchronous stations of automated production lines (electronic gears, synchronous following)

Replace the old DDC-K100A bus driver and adapt to MDD100A/MKD100A motors
