SGDA-02BS

SGDA-02BS is 200W single-phase 100V analog speed/torque servo drive from Yaskawa Sigma-I series; suffix BS = analog speed & torque control only (no digital pulse position input, same control type as SGDA-01BS but higher power rating).

Description

1. Product Overview

SGDA-02BS is 200W single-phase 100V analog speed/torque servo drive from Yaskawa Sigma-I series; suffix BS = analog speed & torque control only (no digital pulse position input, same control type as SGDA-01BS but higher power rating).
Designed to match SGM-02 series 200W 100V Yaskawa servo motor; original production discontinued, only available as maintenance spare parts for legacy automation equipment.

2. Electrical Rating

Power Input

  • Input: Single-phase AC 100～115V, 50/60Hz, rated input current: 8.0A

  • Control circuit shares main power supply (no separate control power terminal)

Output Spec

  • Rated output power: 200W (0.27HP)

  • Continuous output current: 2.7Arms; peak overload current:8.7A (300% short-duration overload capacity)

  • Max three-phase output voltage: AC 0~115V

3. Control Interface (Core Feature: Analog Only, No Pulse Position Command)

  1. CN1 control terminal receives 0~±10VDC analog voltage command for speed reference or torque setting; no differential/open-collector pulse input circuit, cannot perform pulse-type position control (distinguished from SGDA-02BP position model).

  2. Speed control range: 1:5000; default factory setting = speed control mode, switch to torque control via internal parameter modification for tension/winding application.

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

  4. RS232 serial port onboard for SigmaWin software parameter upload/download & running status monitoring; no fieldbus communication function.

  5. Compatible with incremental encoder and battery-backed absolute encoder feedback.

4. Built-in Protection Functions

Overvoltage(OV), Overcurrent(OC), Continuous Overload(OL), Overheat(OH), Encoder cable breakage, Regenerative overvoltage, Power supply abnormality protection; fault code displayed on front digital LED with dry-contact alarm output signal.

5. Environmental & Mechanical Parameters

  • Protection Grade: IP20, cabinet indoor installation only (no water/oil mist allowed)

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

  • Operating humidity:10%~90%RH, no dew formation

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

  • Net weight: approx 1.16kg; certified CE & UL safety standard

6. Main Functions

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

  2. Auto inertia identification & auto gain tuning for speed loop optimization to simplify on-site commissioning.

  3. Built-in dynamic braking circuit for rapid stop during emergency stop or sudden power loss to avoid mechanical overrun.

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

7. Application & Replacement Note

  1. Cannot directly interchange with SGDA-02BP (BP = pulse position control); direct replacement will cause machine malfunction for positioning equipment.

  2. Typical usage: small winding machines, constant-speed feeding rollers, pay-off tension control, precision analog speed regulation automation equipment.
