SGDA-01BS

SGDA-01BS is 100W single-phase AC servo amplifier of Yaskawa Sigma I series, analog speed/torque control type (no pulse position control function, core difference vs SGDA-01BP). It is powered by single-phase AC100~115V, exclusively designed to pair with SGM-01 series 100W 100V-rated Yaskawa servo motors, widely used for analog speed regulation, tension control and constant-torque drive equipment; full production discontinued, available mainly as maintenance replacement spare parts.

Description

1. Product Overview

SGDA-01BS is 100W single-phase AC servo amplifier of Yaskawa Sigma I series, analog speed/torque control type (no pulse position control function, core difference vs SGDA-01BP). It is powered by single-phase AC100~115V, exclusively designed to pair with SGM-01 series 100W 100V-rated Yaskawa servo motors, widely used for analog speed regulation, tension control and constant-torque drive equipment; full production discontinued, available mainly as maintenance replacement spare parts.
Suffix definition:
  • BS = Analog Speed/Torque control model; BP = Digital pulse position control model.

2. Electrical Specifications

Power Ratings

  • Main input: Single-phase AC100~115V, 50/60Hz, rated input current:4.5A; control circuit shares main power supply without independent auxiliary power source

  • Rated continuous output current:2.2Arms; peak overload current:7.1A (300% short-time overload capacity)

  • Max three-phase output voltage:AC115V; rated output power:100W(0.13HP)

Control Interface (Key difference from SGDA-01BP)

  1. CN1 control terminal receives 0~±10VDC analog voltage command for speed or torque setting; no differential/open-collector pulse input circuit, cannot receive pulse position instruction.

  2. Speed control range:1:5000; built-in analog gain adjustment for speed loop; torque limit configurable via parameter or external analog signal.

  3. Standard digital I/O: Servo enable, external fault reset, alarm relay output, JOG forward/reverse, zero-speed detection signal output.

  4. Reserved RS232 serial port for SigmaWin software parameter uploading/downloading and real-time running status monitoring; no fieldbus communication function.

  5. Compatible with incremental encoder and battery-backed absolute encoder feedback, same as BP model.

Full Protection Functions

Overvoltage(OV), overcurrent(OC), continuous overload(OL), overheat(OH), encoder disconnection, regenerative surge, power source abnormality protection; fault codes displayed on front digital indicator upon failure, with dry-contact alarm output signal.

3. Environmental & Mechanical Data

  • Protection class:IP20, must install inside sealed electrical cabinet, forbidden splash water, heavy oil mist and conductive dust

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

  • Allowable humidity:10%~90%RH without dew formation

  • Cooling method:natural air convection cooling, no built-in cooling fan; DIN rail or screw direct mounting available

  • Net weight:approx 0.8kg; CE & UL safety certified

4. Core Functional Features

  1. Factory default mode: analog speed control; switchable to torque control mode by modifying internal parameters for tension/winding application.

  2. Auto inertia identification & auto gain tuning optimizes speed-loop gain automatically to shorten field commissioning cycle.

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

  4. Built-in dynamic brake circuit for rapid motor stopping during emergency stop or sudden power cut to avoid mechanical inertial sliding.

  5. Historical fault code storage in onboard memory for quick troubleshooting during equipment maintenance.

5. Application & Replacement Notice

  1. Cannot directly replace SGDA-01BP (BP is pulse position control, BS is analog speed/torque only); direct swap leads to equipment failure for positioning equipment.

  2. Typical application: small winding machines, feeding roller constant-speed drive, tension pay-off equipment, laboratory precision analog speed test bench.
