YASKAWA JANCD-YBK01-1E SGDR-SDA950A01B-EY26 Servo Drive Module – SGDR Series

YASKAWA JANCD-YBK01-1E / SLC440COM-ER-0650-14 / SGDR-SDA950A01B-EY26: Servo Drive Assembly for High-Precision Motion Control

The YASKAWA JANCD-YBK01-1E paired with the SLC440COM-ER-0650-14 communication board and SGDR-SDA950A01B-EY26 servo amplifier constitutes a complete, factory-matched servo drive assembly engineered for deterministic torque and velocity control in multi-axis industrial robot and CNC environments. This assembly is natively deployed in YASKAWA NX100 and DX100 robot controller platforms, where the JANCD-YBK01-1E control card manages axis interpolation and servo loop closure at the hardware level, the SLC440COM-ER-0650-14 handles real-time fieldbus arbitration, and the SGDR-SDA950A01B-EY26 amplifier delivers 950 W-class output to the connected servo motor. Each component carries a specific hardware revision suffix that governs firmware compatibility — sourcing the exact suffix is mandatory for drop-in field replacement without parameter re-commissioning.

Technical Parameters

Hardware Logical Analysis

The JANCD-YBK01-1E operates as the axis control card within the NX100/DX100 backplane, executing position loop closure at a 1 ms servo cycle period. Its onboard DSP handles forward kinematics interpolation and generates torque reference commands transmitted to the SGDR-SDA950A01B-EY26 amplifier via the internal high-speed parallel bus — bypassing the fieldbus layer entirely for latency-critical servo commands. This architecture separates deterministic servo traffic from non-deterministic network traffic, a design choice that prevents jitter accumulation across multi-axis coordinated motion sequences.

The SGDR-SDA950A01B-EY26 amplifier employs a three-phase IGBT bridge with sinusoidal PWM modulation at a carrier frequency of 8 kHz, producing low torque ripple at low shaft speeds — a characteristic critical for welding and sealing path applications where velocity uniformity directly affects bead quality. The -EY26 hardware revision incorporates an updated gate driver circuit with enhanced short-circuit response time (<2 µs), reducing the risk of IGBT failure under regenerative braking transients in high-inertia load conditions.

The SLC440COM-ER-0650-14 communication board provides the Ethernet physical layer interface between the robot controller and external supervisory systems (SCADA, MES). Its onboard FPGA handles packet timestamping and cycle-synchronization, enabling IEEE 1588 PTP-class synchronization accuracy without burdening the main CPU. The board’s isolated RS-422 diagnostic port allows real-time oscilloscope-level monitoring of servo error signals without interrupting the live control loop — a feature that significantly reduces mean time to diagnose (MTTD) during field troubleshooting.

EMC design on the SGDR amplifier includes a built-in line filter rated to EN 61800-3 Category C2, ferrite-core common-mode chokes on the motor output leads, and a copper ground plane on the control PCB that provides a low-impedance return path for high-frequency noise currents. These measures allow the assembly to operate within 1 m of variable-frequency drives and welding power supplies without measurable degradation in encoder signal integrity.

System Integration Benefits

• Factory-matched revision control: The -1E suffix on JANCD-YBK01-1E and -EY26 on SGDR-SDA950A01B-EY26 are hardware revision identifiers that guarantee parameter-set compatibility — no re-tuning or gain migration is required when replacing like-for-like in an existing NX100/DX100 installation.
• Deterministic 1 ms servo cycle: The JANCD-YBK01-1E closes the position loop at a fixed 1 ms period independent of fieldbus load, ensuring axis synchronization error remains below ±0.01 mm across six-axis coordinated paths.
• Separated servo and network traffic: Internal backplane bus carries servo commands; SLC440COM-ER-0650-14 handles supervisory Ethernet — this dual-bus architecture prevents network congestion from inducing servo jitter.
• Absolute encoder retention: The 17-bit or 20-bit absolute encoder interface on the SGDR amplifier retains axis position through power cycles, eliminating homing routines after planned shutdowns and reducing production restart time.
• Integrated regenerative braking: The SGDR-SDA950A01B-EY26 includes an internal regenerative resistor circuit rated for continuous duty at 950 W load inertia ratios up to 30:1, removing the need for external braking resistors in standard robot arm configurations.
• Real-time diagnostic transparency: The SLC440COM-ER-0650-14 exposes servo error, current feedback, and encoder position data over Ethernet at 10 ms refresh intervals, enabling integration with OPC-UA-based condition monitoring platforms without additional hardware.
• Enhanced EMC margin: Built-in C2-class line filter and common-mode chokes allow installation in mixed-drive panels without additional external filtering, reducing panel BOM cost and wiring complexity.
• SigmaWin+ compatibility: Full parameter read/write and auto-tuning support via YASKAWA SigmaWin+ software, enabling offline parameter backup and rapid parameter restore after board replacement.
