Yaskawa SGMAS-06ACA 600W Sigma-III AC Servo Motor

Description

Product Introduction

The Yaskawa SGMAS-06ACA is a 600-Watt AC rotary servo motor built for high-speed, dynamic positioning applications within the Yaskawa Sigma-III motor platform. Paired with SGDV or SGDS Sigma series SERVOPACK drivers, the SGMAS line provides ultra-smooth motion profiles, minimal torque ripple, and high frequency response for critical industrial automation tasks.

Featuring a 17-bit high-resolution feedback encoder (131,072 pulses per revolution), the SGMAS-06ACA eliminates position hunting and vibration at standstill. Its medium-inertia rotor design delivers an ideal balance between rapid acceleration dynamics and load-inertia matching, making it suitable for high-duty cycle equipment like pick-and-place robots, electronic component inserters, and packaging machinery.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

It’s 2:45 AM on an automated packaging line. The X-axis transfer gantry throws an A.810 encoder communication fault or A.710 overload alarm, dropping the main line offline. A damaged motor feedback winding or locked bearing on the current 600W servo stops throughput completely. Retrofitting the axis to a newer Sigma-7 motor requires replacing the drive, running new feedback cables, and recalibrating the motion controller’s gain parameters. You need a drop-in Yaskawa SGMAS-06ACA motor to mount directly to the original gearbox flange, plug into the existing harnesses, and resume production.

• Semiconductor & PCB Assembly – High-Speed Pick-and-Place – Delivers sub-millimeter positioning accuracy across continuous placement cycles.
• Automated Packaging Machinery – Flying Cutters & Indexers – Executes rapid acceleration and deceleration ramps up to 6000 RPM maximum speed without overshooting target coordinates.
• Robotics & Material Handling – Multi-Axis Transfer Gantries – Medium-inertia design offers mechanical stability when driving long-reach timing belt axes.

Field Case Study:

A medical device manufacturer in Massachusetts experienced an internal encoder failure on an SGMAS-06ACA motor controlling a high-speed syringe filling indexing table. The failure triggered an immediate station lock. We dispatched a verified surplus SGMAS-06ACA motor via priority air shipment. The facility technician unbolted the failed unit, transferred the flexible coupling, reconnected the military-style IP65 connectors, and restored calibrated operation within 30 minutes of receipt.

Transparency SOP: Quality Assurance & Testing

We don’t just ship boxes; we test them on actual Yaskawa SGDV/SGDS SERVOPACK benches.

1. Inbound Physical Inspection: Inspection of the front shaft for scoring or runout, check rear encoder housing for impact damage, and verify pin condition on power and feedback connectors.
2. Winding Resistance & Megohmmeter Test: Phase-to-phase resistance measurements (U-V, V-W, W-U) to verify balanced stator coils, followed by a 500V DC megger test to check insulation integrity to chassis ground.
3. Closed-Loop SERVOPACK Drive Run: Motor is connected to a matching Yaskawa SGDV servo drive to execute full-speed sweeps up to 6000 RPM in both CW and CCW directions.
4. Encoder Data Line Audit: Verification of 17-bit serial encoder data transmission, checking absolute position memory retention and zero-mark pulse clarity.
5. Anti-Static & ESD Packaging: Cleaned, wrapped in heavy protective moisture-barrier material, and packed in reinforced shock-absorbing foam.

The Veteran’s Tech Trap Guide

⚠️ Decode Your Full Model Suffix (SGMAS-06ACA-xx):

The base code covers a 600W, 200V motor with a standard encoder. However, the tail suffix characters specify critical mechanical options:

• SGMAS-06ACA21: Shaft with keyway and tap.
• SGMAS-06ACA2C: Shaft with keyway, tap, and 24V holding brake.

  Installing a motor without a holding brake on a vertical Z-axis will cause the load to drop whenever main power is disabled.

❗ Never Strike the Motor Shaft with a Hammer:

When installing pulleys, gears, or flexible couplings onto the motor shaft, use a proper wheel puller or threaded draw-bolt tool. Tapping or hammering directly on the shaft end destroys the internal high-precision ball bearings and shatters the glass disk inside the rear 17-bit optical encoder.

⚠️ Maintain Proper Drip Loops on Connectors:

Even though the SGMAS body is IP65 rated, liquid entering unsealed connector hoods will short the 17-bit encoder lines. Always install power and encoder cables with a drip loop so condensation drains away from the motor body.

Frequently Asked Questions

Q: Can I drive the SGMAS-06ACA with a non-Yaskawa servo amplifier?

A: No. The 17-bit serial encoder utilizes Yaskawa’s proprietary communication protocol. The motor must be paired with a compatible Yaskawa SERVOPACK (such as the SGDV, SGDS, or SGD7S series configured for legacy support).

Q: What is the difference between the SGMAS and SGMPH series motors?

A: Both are medium-inertia motors, but the SGMAS is part of the Sigma-III platform featuring higher encoder resolution (17-bit vs 13-bit on older SGMPH), a more compact frame length, and higher peak speed capability (up to 6000 RPM).

Q: How can I tell if an SGMAS-06ACA motor has a built-in holding brake?

A: Check the model number on the nameplate. Units with an internal 24V DC holding brake feature a C or E in the 7th or 8th character position (e.g., SGMAS-06ACA2C). Brake models also feature a longer overall body frame.

Q: Do I need to set up absolute encoder parameters after swapping this motor?

A: If running in absolute mode, you must perform an absolute encoder reset (clear multi-turn data) via the SERVOPACK operator panel or SigmaWin+ software upon installing a replacement motor.

Q: What warranty is provided with this surplus motor?

A: Every Yaskawa SGMAS-06ACA motor supplied is backed by a full 12-month replacement warranty. If the unit experiences mechanical or electrical failure under normal operating conditions during the warranty period, we replace it directly from stock.
