1. Part Number Breakdown

• DDC: Digital Drive Controller (compact servo drive)

• 01.1: Series 01, hardware revision 1

• K100A: K=compact; 100=100 A; A=analog base

• DL01-01: D=digital feedback; L=DLC positioning + analog; 01=func code; 01=variant

• -FW: Firmware suffix – indicates drive is supplied with or requires dedicated firmware (not blank/hardware-only)

2. Technical Specifications (Electrical / Mechanical)

Electrical

• Input: 3×AC 380–460 V, 50/60 Hz

• Control Voltage: 24 VDC

• Continuous Output: 100 A

• Peak Output: 200 A (1 s)

• DC Bus: Integrated rectifier, ~700 VDC

• PWM Frequency: 4 kHz

Mechanical & Environmental

• Dimensions (H×W×D): 360 × 155 × 261 mm

• Weight: ~12.5 kg

• Protection: IP65 (machine-mountable)

• Operating Temp: 0 °C to +45 °C (full load)

• Storage Temp: −20 °C to +80 °C

Control & Interfaces

• Modes: Position (DLC) / velocity / torque

• Feedback: Digital servo (MDD motor, multiturn encoder)

• Command: DLC 2.1 positioning bus + ±10 V analog

• Comm: RS-232/RS-485 (diagnostics), DLC bus

• Protection: Overcurrent, overvoltage, overtemperature, short circuit, STO

3. What “FW” Means (Critical Difference)

• No suffix (e.g., DL01-01): Hardware-only, firmware must be loaded separately (not included)

• -FW suffix (DL01-01-FW): Firmware is part of the part number – supplied with standard DL01-01 firmware, or ordered as a firmware-bearing unit

• Why it matters: For spare parts/retrofits, -FW = ready to run (no separate firmware file needed)

4. DL01-01-FW vs Other DDC Interfaces

• DA: Only analog ±10 V

• DG: Analog + RS-485 digital

• DS: Only digital (SERCOS)

• DL-FW: DLC positioning + analog, firmware included

• Best for: Single-axis positioning, CNC retrofits, mixed analog/DLC systems

5. Applications

• CNC machine tools (milling, turning, grinding)

• Single-axis positioning systems

• Retrofit projects (analog → DLC positioning)

• Industrial automation with mixed control types
