DMD02.1-W082N

Model Definition DMD: MiniDrive compact standalone servo drive family 02.1: Second generation core control board hardware revision W082N: Power stage specification; continuous output 4.2A RMS, peak overload 8.2A RMS, N = passive natural convection cooling without built-in cooling fan

Description

Technical Parameters

  1. Input Power: Single-phase / three-phase universal AC 200~240V, 50/60Hz, internal integrated rectifier circuit

  2. Output Rating: Continuous 4.2Arms, peak transient 8.2Arms, nominal rated output power 750W, matched MMD082 series servo motor

  3. PWM Switching Frequency: Fixed default 8kHz carrier frequency

  4. Cooling Specification: Passive heat sink natural cooling, output power derating required when ambient exceeds 40°C

  5. Ambient Environment: Rated operation temperature 0°C~+45°C, storage -20°C~+70°C, non-condensing relative humidity ≤70%, IP20 cabinet-only installation

  6. Dimension & Weight: W120×H200×D45mm, net weight approx 1.2kg

  7. Feedback Compatibility: DB15 interface for standard TTL incremental encoder, resolver support available via customized wiring modification

  8. Auxiliary Power: Control circuit powered internally from main AC input, external 24VDC auxiliary supply not needed

Interface & Communication Configuration

Main Power Terminals

Screw terminal block for L1/L2/L3 AC input and PE protective earth connection

Motor Power Terminals

U/V/W three-phase motor power output plus independent terminal for motor electromagnetic holding brake supply

Motor Feedback Port

DB15 dedicated connector for incremental encoder position feedback signal connection

Analog Command Interface

±10V differential analog input for external speed or position reference signal from upper controller

Digital I/O Terminals

24VDC rated discrete I/O terminals: servo enable, forward/reverse jog command, positive/negative limit input, fault dry-contact relay output

Front Debug Interface

Numeric LED display to show running speed, parameter values and fault codes; front physical buttons for local jog operation and parameter setting

Core Functions

  1. Full digital triple closed-loop control of current, speed and position loop; embedded automatic motor parameter identification and auto-tuning algorithm

  2. Two standard operation modes: external ±10V analog command control or local manual jog via front panel buttons

  3. Comprehensive full-range protection: overcurrent, overvoltage, mains undervoltage, overtemperature, encoder missing, output short-circuit and motor stall protection with coded fault display

  4. Built-in dynamic braking circuit for regular small-inertia load deceleration energy consumption, external brake resistor unnecessary under standard operating conditions

  5. Programmable holding brake delay control, brake output status interlocked with servo running state

  6. All working parameters saved in onboard nonvolatile memory without extra memory card for data backup

Application Scenarios

  • Auxiliary feed axes for small bench CNC milling, drilling and compact grinding equipment

  • Medium-load labeling, blister packaging and short-stroke conveyor precision positioning drive

  • Small printing roller and lightweight textile knitting machine transmission servo system

  • Spare replacement and refurbishment for outdated original MiniDrive automation production equipment

  • Compact indexing turntable and laboratory test fixture medium-torque precision positioning equipment
