1. Model Segmentation Analysis (Including FW)

DDC: Digital Drive Controller

01.2: First generation, hardware version 2 (heat dissipation and EMC optimization)

N050C:

N = Natural convection (no fan)

050 = 50A continuous output current

C = Low noise version

DA02:

DA = Analog interface (±10V)

02 = Enhanced analog function code

01: Hardware revision version 01

FW: Firmware preloaded, factory-installed standard firmware (FWA-DIAX02-ASED A02-01-FW)

2. Core Electrical Parameters

Input Voltage: 3×AC 380–460V, 50/60Hz

Control Power Supply: 24VDC

Continuous Output: 50A; Peak: 100A (1 second)

DC Bus: ≈700VDC

Switching Frequency: 4kHz

Protection: STO, Overcurrent, Overvoltage, Overheat, Phase Missing, Ground Fault

3. Mechanical and Environmental

Size (H×W×D): ≈517.5×165×298 mm

Weight: ≈21 kg

Protection Grade: IP65 (dust-proof, oil-proof, splash-proof)

Operating Temperature: +5°C～+45°C (full load); Maximum + 55°C (derated)

Cooling Method: Natural cooling (no fan), low maintenance, dust-proof

4. Control and Interface

Feedback Type: D = Digital (compatible with MDD/MKD motors)

Command Interface: DA02 = Enhanced analog ±10V (speed/torque control)

Communication: RS-232/485 (parameter setting, diagnosis)

No fieldbus (if a bus is needed, choose DL/DS/DG series)

5. Compatible Motors (50A Frame)

MDD Series: MDD041A, MDD056A

MKD Series: MKD041B, MKD056B

6. Key Significance of FW

FW = Firmware pre-installed, ready to use upon arrival, no need to purchase or burn firmware separately

FW Version: FWA-DIAX02-ASED A02-01-FW (strictly matched with hardware)

Non-FW Version (such as DDC01.2-N050C-DA02-00): Does not contain firmware, needs to be purchased and burned separately

7. Typical Applications

Low-power single-axis positioning (50A)

Machine tool auxiliary axes, packaging machinery, textile machinery, electronic equipment

Dust-free / Low-noise / Low-maintenance scenarios (no fan)
