YASKAWA SGDV-1R6A11B Sigma-5 SERVOPACK Servo Drive 200V 1.6A

Compact Servo Amplifier for Yaskawa Sigma-5 Rotary Servomotors

Specifications

Industrial Applications

• Packaging machines — feeding, cutting, sealing and labelling axes that need fast, repeatable positioning.
• Material handling and conveyor systems — indexing tables, diverters, gantries and pick-and-place units.
• Machine tools and metalworking equipment — auxiliary axes, tool changers and feed drives.
• Robot cells and small motion platforms driving SGMJV / SGMGV rotary servomotors from Yaskawa controllers.
• Semiconductor and electronics assembly equipment where high resolution and short settling times matter.
• Textile, printing and converting machinery running multi-axis synchronized motion over MECHATROLINK-II.

Design Purpose

The SERVOPACK SGDV is the amplifier stage between the motion controller and the servomotor. A host controller sends motion commands over MECHATROLINK-II; the amplifier converts those commands into precisely controlled motor current using IGBT-based PWM with sine-wave current control, closed by the encoder feedback coming back from the motor. The job is not simply to vary speed — it is to hold position, regulate speed and limit torque accurately, repeatedly and fast. That is the fundamental difference from the variable-frequency drives in this catalog: a VFD varies the speed of an induction motor for fans, pumps and conveyors, while this servo amplifier closes a high-resolution loop around a permanent-magnet rotary servomotor for motion control.

The rating defines its place. At 200 W output and 1.6 A continuous, this unit serves the small-axis end of the Sigma-5 range — light loads, small frameless mechanisms, feeder and indexing drives — rather than large press or gantry axes. Because it is a MECHATROLINK-II reference model for rotary servomotors, selection must match three things at once: the servomotor model (SGMJV / SGMGV), the command interface expected by your host controller, and the encoder cabling. Substituting the interface variant changes the part number, so the order code SGDV-1R6A11B should be matched against your existing unit rather than chosen by power rating alone.

Common Failure Modes

• Overcurrent alarm — a shorted motor or encoder cable, a grounded motor winding or a mechanically jammed load drives protective shutdown. Related troubleshooting: see our article on "Yaskawa Sigma-5 Servo Amplifier Overcurrent Alarm Troubleshooting".
• Overvoltage or regenerative overload alarm — frequent emergency stops and high-inertia loads push regenerated energy back into the DC bus; a correctly sized regenerative resistor is often required. Related troubleshooting: see our article on "Yaskawa SGDV Overvoltage and Regenerative Overload Alarm Fix".
• Encoder error or feedback loss — damaged encoder wiring, contamination or electrical noise interrupts the closed loop, leaving the axis unable to hold position. Related troubleshooting: see our article on "Yaskawa SERVOPACK Encoder Error Diagnosis and Repair".
• Main-circuit supply error or low-voltage alarm — supply dips, loose terminals or a failed contactor drop the bus below the amplifier's threshold. Related troubleshooting: see our article on "Yaskawa Sigma-5 Servo Amplifier Low Voltage Alarm Causes".
• Thermal fault / overheating — blocked ventilation, high ambient temperature or a heatsink loaded with dust raises internal temperature. Related troubleshooting: see our article on "Yaskawa SERVOPACK Overheating and Ventilation Check".
• Parameter loss or servo-not-ready — corrupted or cleared parameters leave the amplifier unable to enable the axis after replacement. Related troubleshooting: see our article on "Yaskawa Sigma-5 MECHATROLINK-II Communication Setup Guide".
