DMD02.1-W042N

Model Definition DMD: MiniDrive compact independent servo amplifier series 02.1: Second-generation main hardware PCB revision version W042N: Power grade identifier; continuous rated output current 2.1A, peak 4.2A, natural convection cooling standard version(N suffix = no built-in cooling fan)

Description

Technical Parameters

  1. Input Supply: Single/3-phase AC 200~240V, 50/60Hz, built-in input rectifier circuit

  2. Output Rating: Continuous 2.1Arms, peak transient 4.2Arms, matched MMD042 permanent magnet servo motor, rated output approx 400W

  3. PWM Frequency: Fixed 8kHz default carrier frequency

  4. Cooling Type: Passive natural heat sink cooling, power derating mandatory above +40℃ ambient temperature

  5. Ambient Condition: Operation 0℃~+45℃ without deration, storage -20℃~+70℃, relative humidity ≤70% non-condensing, IP20 cabinet mounting only

  6. Dimension & Weight: W120×H200×D45mm, net weight ~1.1kg

  7. Feedback Compatibility: DB15 interface for TTL incremental encoder; resolver available with optional modification

  8. Control Power: Auxiliary control power sourced internally from main AC input, independent 24VDC supply unnecessary

Interface & Communication Configuration

Main Power Terminals

Screw terminals for L1/L2/L3 AC mains input plus PE earth terminal

Motor Power Terminals

U/V/W three-phase motor winding output and separate terminal for motor holding brake supply

Feedback Connector

DB15 dedicated socket for incremental encoder position feedback signal wiring

Analog Reference Interface

±10V differential analog input for external speed or position command signal

Digital I/O Terminals

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

Local Debug Interface

Front LED numeric display for parameter value, operational speed and fault codes; onboard push buttons for manual jogging and local parameter setup

Core Functions

  1. Full digital triple closed-loop regulation: current, speed and position loop control; integrated automatic motor identification and auto-tuning routine

  2. Two standard control modes: ±10V external analog command control or local panel jog fixed-speed operation

  3. Full protection suite: overcurrent, overvoltage, undervoltage, overtemperature, encoder loss, output short-circuit and motor stall protection with coded fault indication

  4. Onboard dynamic braking circuit for low-inertia load deceleration energy dissipation, external brake resistor not required for regular application

  5. Configurable electromagnetic holding brake delay timing, brake output interlocked with servo operational status

  6. Nonvolatile onboard memory stores all drive parameters without auxiliary memory card

Application Scenarios

  • Small auxiliary feed axes of miniature CNC equipment, bench drill and compact grinding machines

  • Small labeling, blister packaging and lightweight conveyor positioning servo drive

  • Mini textile machinery, small printing roller precision transmission equipment

  • Refurbishment spare replacement for aging MiniDrive original automation equipment

  • Laboratory test fixtures, compact small indexing turntable low-power precision positioning system
