Description

1. Model Definition & Basic Info

Brand: Yaskawa Electric Japan
Series: Legacy analog Σ1 CACR rack-type servo amplifier, early industrial OEM customized version

  • CACR = Yaskawa traditional SERVOPACK servo drive family

  • A1 = Rated power 100W(0.1kW) small-power grade

  • NF3A = Custom hardware code: 3-phase AC200V input + dedicated encoder circuit + OEM preset parameter for special equipment

    Matching Motor: Yaskawa USA/USAFED 100W, 200V class incremental encoder servo motor

    Supply Status: Full production discontinued; only used/refurbished spare parts for equipment maintenance (semiconductor, precision automation equipment)

2. Electrical Specifications

Input Power

3-Phase AC200~230V, 50/60Hz; control power single-phase AC200V

Output Rating

Rated output: 100W; continuous output current:1.2A; peak overload current 3.6A (300% overload for acceleration)

Control Modes

3-in-1 configurable control: Position(Pulse command) / Speed(±10VDC analog) / Torque(±10VDC analog)

  • Position input: Line driver / open-collector CW/CCW pulse signal

3. Connector Interface

  • CN1: 24VDC opto-isolated DI/DO terminal: Servo ON, alarm output, in-position complete, interlock signal

  • CN2: 5V A/B/Z incremental encoder feedback port (match 1000~2500P/R Yaskawa old encoder)

  • CN3: Composite port for pulse + analog command signal

  • Built-in debug serial port for PC parameter read/write & fault check

4. Mechanical & Ambient Data

  • Mounting: Standard DIN rack mounting (plug-in cabinet module structure)

  • Cooling: Natural convection, IP20 protection

  • Operating temp: 0~50℃; Storage temp: -20~60℃; Humidity 5~95%RH non-condensing

  • Net weight: ~0.8kg

5. Protection Functions

OC overcurrent, OV overvoltage, UV undervoltage, motor overload, heatsink overheat, encoder break, output short-circuit; dry-contact alarm output for host controller.

6. Upgrade Replacement

Modern alternative: Yaskawa Sigma7 SGD7S-R90A00A (100W, AC200V) digital servo drive, partial wiring modification required.
