YASKAWA SGDV-5R4D11A020000 AC Servo Drive – Sigma-V Series

YASKAWA SGDV-5R4D11A020000 Sigma-V SERVOPACK — Precision Servo Amplifier for Closed-Loop Motion Control

The YASKAWA SGDV-5R4D11A020000 is a 200 V class, 5.4 A rated AC servo amplifier belonging to the Σ-V (Sigma-V) SERVOPACK family. Within a closed-loop motion control architecture, this unit occupies the power conversion and command execution layer: it receives position, speed, or torque references from an upstream controller, conditions three-phase AC power through an internal IGBT bridge, and delivers precisely regulated current to the paired servo motor. The drive’s internal DSP executes current-loop closure at a 62.5 µs cycle, position and speed loops at 125 µs, ensuring deterministic response that satisfies the timing budgets of high-throughput automation cells.

The model suffix 5R4D11A020000 encodes specific hardware configuration: the 5R4 designates the 5.4 A continuous output current class; D indicates the 200 V DC bus voltage class; 11A specifies the analog/pulse-train command interface with the standard I/O option card; and 020000 identifies the safety function and option slot configuration. Engineers specifying this unit must verify that each suffix field matches the application’s interface, safety, and power requirements before procurement.

Technical Parameters

Hardware Logical Analysis

IGBT Power Stage and Gate Drive Architecture: The SGDV-5R4D11A020000 employs a three-phase full-bridge IGBT inverter with integrated gate drive circuits. Gate signals are generated by the DSP at 8 kHz carrier frequency, producing sinusoidal PWM output with low harmonic distortion. Dead-time compensation is applied in firmware to eliminate the voltage error introduced by IGBT switching delays, maintaining torque linearity at low speeds where back-EMF is insufficient to mask commutation artifacts.

Current Sensing and Feedback Path: Phase current is sampled via shunt resistors on two of the three output legs. The third phase current is reconstructed by Kirchhoff’s current law. Sampling is synchronized to the PWM carrier peak to avoid switching noise aliasing. The 62.5 µs current loop executes a PI regulator in the d-q rotating reference frame, decoupling flux-producing and torque-producing current components for independent control.

EMC Design and Noise Immunity: The drive’s PCB layout separates high-current switching traces from low-level signal traces with a ground plane interposed between layers. Common-mode chokes are integrated on the AC input lines. The chassis is bonded to protective earth through a low-impedance path, and the encoder cable shield is terminated at the drive end to a dedicated shield clamp, preventing ground loops. These measures allow the unit to meet EN 61800-3 Category C2 conducted and radiated emission limits without external line filters in most installations.

Vibration Suppression and Notch Filter Logic: The Σ-V firmware implements a two-stage vibration suppression algorithm. The first stage applies a notch filter tunable from 50 Hz to 5000 Hz to cancel mechanical resonance frequencies identified during auto-tuning. The second stage uses a low-pass filter on the torque reference to attenuate high-frequency excitation of flexible load elements. Both filter parameters are stored in non-volatile EEPROM and survive power cycles without re-tuning.

Absolute Encoder Battery Backup: When paired with a 20-bit absolute encoder, the drive’s CN1 connector provides a 3.6 V lithium battery interface. The battery maintains encoder position data during power-off, eliminating homing cycles on restart. Battery voltage is monitored continuously; a low-battery alarm (A.830) is generated when voltage drops below 2.7 V, providing advance warning before data loss occurs.

Regenerative Energy Management: During deceleration, kinetic energy from the motor and load is returned to the DC bus. The internal regenerative resistor dissipates this energy when bus voltage exceeds the overvoltage threshold (approximately 400 V DC for the 200 V class). For applications with frequent or high-inertia deceleration cycles, an external regenerative resistor can be connected to the RB terminals, increasing the drive’s continuous regenerative power capacity beyond the internal resistor’s rating.

System Integration Benefits

• Deterministic dual-loop timing: Current loop at 62.5 µs and position/speed loop at 125 µs provide predictable latency budgets for system-level cycle time calculations in multi-axis coordinated motion.
• High-resolution absolute feedback: 20-bit serial absolute encoder support delivers 1,048,576 counts per revolution, enabling sub-arc-second angular positioning without mechanical homing on power-up.
• Adaptive auto-tuning (one-parameter tuning): The drive estimates load inertia ratio in real time and adjusts gain settings automatically, reducing commissioning time from hours to minutes on standard rigid-load applications.
• Programmable I/O mapping: All 8 digital inputs and 6 digital outputs are software-assignable to functions including servo-on, alarm reset, forward/reverse inhibit, brake release, and positioning complete, eliminating fixed-wiring constraints.
• Dual analog monitor outputs: Two 12-bit analog outputs provide real-time visibility of internal variables (speed feedback, torque reference, position error) for oscilloscope-based diagnostics without interrupting production.
• Fault history logging: The drive stores the last 10 fault codes with timestamps in non-volatile memory, accessible via SigmaWin+ software, enabling root-cause analysis without on-site instrumentation.
• Dynamic brake for safe deceleration: On servo-off or fault, the built-in dynamic brake shorts the motor terminals through a resistor network, decelerating the load in a controlled manner without requiring an external braking contactor in most applications.
• Compatibility with standard PLC pulse outputs: The pulse-train interface accepts open-collector signals up to 200 kpps and line-driver signals up to 4 Mpps, covering the output specifications of virtually all major PLC brands including Siemens, Mitsubishi, Omron, and Keyence positioning modules.
• SigmaWin+ software integration: The RS-422 port connects to YASKAWA’s SigmaWin+ engineering tool for parameter backup, waveform capture, FFT-based resonance analysis, and firmware updates, supporting the full product lifecycle from commissioning to maintenance.
• Compact DIN-rail-compatible form factor: At 1.87 kg and a narrow width profile, the unit fits standard 600 mm deep control cabinets with adequate clearance for airflow, reducing panel engineering effort.
