1. Product Overview

• A: Rated input AC 200~230V;

• P: Digital pulse input for position control (supports position/speed/torque three control modes, differs from BS analog-only models).

  Matching servo motor: Yaskawa SGM-08 series 750W 200V AC servo motor; original production discontinued, only supplied as spare replacement for legacy automation equipment.

2. Electrical Ratings

Input Power

• Input: Single-phase AC 200~230V, 50/60Hz; rated input current: 11.0A

• Control power is powered from main circuit supply (no independent auxiliary control power terminal)

Output Specifications

• Rated continuous output power: 750W

• Continuous output current: 4.4Arms, peak overload current:13.2A (300% short-time overload capacity)

• Max three-phase output voltage: AC 0~230V

3. Control Interface & Working Modes

1. CN1 control connector accepts two types of pulse commands: line-driver differential pulse or open-collector pulse (step/direction, CW/CCW dual-pulse format) for high-precision positioning control (default factory setting: Position Control Mode).

2. Three switchable operation modes via internal parameter setup:

   • Position Control (digital pulse command input)

   • Speed Control (0~±10VDC analog voltage reference)

   • Torque Control (0~±10VDC analog torque setting)

3. Standard built-in digital I/O terminals: Servo ON enable, external fault reset, JOG forward/reverse trigger, positioning complete output, zero-speed signal output, dry-contact alarm relay output.

4. Onboard RS232 serial port for SigmaWin software parameter read/write and real-time operation status monitoring; no standard fieldbus communication interface.

5. Compatible with standard 2048P/R incremental encoder and battery-backed absolute encoder feedback.

4. Built-in Protection Functions

5. Environmental & Mechanical Parameters

• Protection Grade: IP20, only indoor cabinet installation (keep away from water splash, oil mist and conductive dust)

• Operating ambient temperature: 0℃ ~ +55℃ (non-condensing); storage temperature: -20℃ ~ +85℃

• Working humidity: 10%~90%RH without dew condensation

• Cooling method: Natural air convection cooling, no built-in cooling fan; fixed via DIN rail or cabinet screw mounting

• Net weight: approx 1.4kg; certified UL & CE safety standards

6. Main Functional Features

1. Front-panel independent JOG inching function for manual motor forward/reverse test without external controller connection.

2. Auto load inertia identification and automatic gain tuning for speed/position loop optimization to shorten field debugging cycle.

3. Integrated dynamic braking circuit for rapid stop during emergency stop or unexpected power failure to prevent mechanical overtravel.

4. Internal memory stores historical fault codes for convenient equipment failure troubleshooting.

7. Application & Replacement Tips

1. Cannot directly replace SGDA-08BS (BS = analog speed/torque only without pulse position input); incorrect replacement leads to positioning failure of automated equipment.

2. Typical application scenarios: Precision indexing machinery, automatic feeding axes, small CNC auxiliary spindle, packaging positioning equipment, electronic component assembling automation, printing transport mechanism.
