Yaskawa: AC Servo System Σ7 Servo Motor SGM7J-01AFC6E and Servo Drive SGD7S-R90A00A

Servo Motor SGM7J-01AFC6E

The SGM7J was designed to maximize responsiveness in applications where precise load matching is of critical importance. This family of medium inertia rotary servo motors was created with low capacity applications in mind yet can respond with rated speeds to 3000 rpm and torque ratings up to 2.39 Nm. When an application requires it. 24-bit encoder resolution maintains industry-leading positional accuracy in any operating condition.

Features

• 24-bit encoder resolution
• More compact than other motors with similar ratings, for a better fit in tight spaces
• Completely compatible with Sigma-7 servos
• Neodymium iron boron permanent magnets with a high flux density reduce rotor size
• Advanced magnetic circuitry and optimum winding geometry deliver very low cogging torque
• Safety rated at SIL 3 (IEC 61508)
• IP67 rated for resistance to dust, water washdown
• Functions in temperatures above 60oC, altitudes above 2000 ft.
• Peak acceleration torques up to 300% of rated torque
• Peak torque can be maintained for up to three seconds
• Rated speed of 3,000 rpm, max speed of 6,000 rpm
• Runs 20% cooler than previous generation products
• Holding Brake and Shaft Seal option available

Servo Drive SGD7S-R90A00A

Compact, cost-saving single axis controller/amplifier

Put complete control for a single axis of servo motion in one compact unit that conserves space in control cabinets. Sigma-7 Siec combines a Sigma-7 SERVOPACK amplifier and one axis of machine control in the space of a conventional amplifier, at a significant savings when compared to a pair of separate components.

Features

Single Axis Controller Features

• Compact package
• IEC61131-3 and PLCopen programming standard
• Controller and SERVOPACK integrated in one compact unit
• Single axis of motion control
• Open standards EtherNet/IP and Modbus TCP for connectivity to nearly every PLC, HMI and remote I/O (Including our very own VIPA SLIO I/O) on the market
• Built-in web server with standard controller diagnostic features

Note: The Sigma-7Siec does not have internal battery backed RAM

SERVOPACK Features

• Industry-leading 3.1kHz bandwidth significantly improves settling time.
• Tuning-less capability reliably tunes servo system automatically - no user adjustment needed.
• Powerful package of tuning functions include compensation for the effects of machine inertia, vibration, friction, and ripples in output.
• Maintains tuning accuracy despite inertia changes up to 30:1.
• IEC 61508 SIL3 safety certification.
• Completely compatible with Sigma-5 servo motors.
• Improved filtering minimizes inaccuracies due to electrical interference, machine resonance and mechanical vibration.
