What Is the USB-JZSP-CMS02 Yaskawa Servo Debugging Cable?

The USB-JZSP-CMS02 is a communication cable that connects a Windows PC directly to Yaskawa Sigma-II and Sigma-III series servo drives and servo amplifiers via their CN3 communication port. It enables engineers and technicians to run Yaskawa's SigmaWin+ software for parameter configuration, servo tuning, alarm diagnosis, waveform tracing, and firmware management. This cable is essential for commissioning new servo systems, troubleshooting drive faults, backing up parameter sets, and performing preventive maintenance on Yaskawa motion control installations.

In short: If you need to connect your laptop to a Yaskawa Sigma-II or Sigma-III servo drive for setup, tuning, or diagnostics, this USB-JZSP-CMS02 cable is the tool you need, available from koeed.com.

Why This Cable Matters

1. Direct PC-to-Servo Communication

What it means: The USB-JZSP-CMS02 converts USB from your PC to the RS-422/RS-485 serial protocol used by Sigma-II and Sigma-III drives, with the JZSP-CMS02 connector mating directly with the drive's CN3 port.
Why it matters: Without this cable, you cannot access the drive's internal parameters, monitor real-time servo performance, or read fault histories. You are limited to the 5-digit LED display on the drive front panel.
Result: Full access to every drive parameter, digital oscilloscope functions, and one-click parameter backup from your laptop.

2. Essential for Drive Replacement and Commissioning

What it means: When swapping a failed Sigma-II or Sigma-III drive, you can upload the parameter set from the old drive (if still readable), save it to a file, and download it to the replacement drive in seconds.
Why it matters: Manually entering 100+ servo parameters through the front panel keypad is error-prone and time-consuming - one mis-typed gain value can cause oscillation or positioning error.
Result: Exact parameter cloning between old and new drives, eliminating setup mistakes and reducing machine downtime to minutes instead of hours.

3. Advanced Diagnostics Through SigmaWin+

What it means: With the cable connected, SigmaWin+ software provides real-time waveform capture of motor speed, torque, position error, and command signals at the drive's servo loop update rate.
Why it matters: Intermittent faults like occasional position overshoot, vibration at specific speeds, or sporadic alarm triggers are nearly impossible to diagnose from the LED display alone. The waveform trace captures the exact moment of the anomaly.
Result: Faster root-cause diagnosis of complex servo issues without swapping hardware blindly.

Technical Specifications

USB driver installation is required before first use. Download the driver from Yaskawa's support site or Windows Update. SigmaWin+ software is available as a free download from Yaskawa's official website.

Typical Use Cases

• New Machine Commissioning: Configure servo parameters, tune gains, and verify motor direction before the machine runs production
• Drive Replacement: Backup parameters from the old drive, swap hardware, and restore settings to the new unit in minutes
• Troubleshooting: Read alarm codes with detailed descriptions, capture waveform traces of position and torque during fault events
• Preventive Maintenance: Periodically save parameter sets as a backup; compare current settings against the original commissioning values
• Firmware Updates: Update drive firmware when Yaskawa releases improvements or bug fixes for Sigma-II/III series
• Multi-Axis Setup: Configure and tune multiple drives across a production line from a single laptop

Frequently Asked Questions

Does this cable work with Sigma-5, Sigma-7, or Sigma Logic drives?

This cable is specifically designed for Sigma-II and Sigma-III series servo drives with the CN3 communication port. Sigma-5, Sigma-7, and later Sigma Logic models use a different communication connector (typically mini-USB or Ethernet). Check your drive model number: if it begins with SGDH (Sigma-II) or SGDM/SGDS (Sigma-III), this cable is compatible. For newer Sigma series drives, contact us and we can recommend the correct communication cable for your model.

Where do I download the SigmaWin+ software and USB driver?

SigmaWin+ is available as a free download from Yaskawa's official website under the Support > Software Downloads section. You will need to create a free account to access the download. The USB driver for this cable is typically included with the SigmaWin+ installation package. If Windows does not automatically install the driver when you plug in the cable, download it separately from the Yaskawa support site. Our team can provide the direct download link if needed.

My PC does not recognize the cable - what should I check?

First, confirm the USB driver is installed by checking Device Manager for any unrecognized devices with a yellow exclamation mark. If the driver is correctly installed, the cable should appear as a COM port under Ports (COM & LPT). Second, verify SigmaWin+ is configured to use the correct COM port number. Third, confirm the drive is powered on - the CN3 port is only active when the drive has control power. If all three are correct and connection still fails, try a different USB port on your PC or test the cable on a known-working drive to isolate the issue.

Can I leave this cable connected permanently for monitoring?

While technically possible, it is not recommended. The CN3 port is a service port, not designed for permanent connection in a production environment. Vibration, cable strain, and electrical noise can cause intermittent communication drops or, in rare cases, interfere with drive operation. Use the cable for commissioning, troubleshooting, and periodic maintenance, then disconnect it and store it safely. For permanent monitoring solutions, consider Yaskawa's fieldbus options (Mechatrolink, EtherCAT, etc.) available on newer drive series.

Is this a genuine Yaskawa cable or a third-party compatible?

This listing is for a USB-JZSP-CMS02 cable suitable for Yaskawa Sigma-II/III drives. It provides full SigmaWin+ communication functionality including parameter read/write, waveform tracing, and firmware operations. Contact our team if you require confirmation of the manufacturing source. In either case, the cable is tested to work with SigmaWin+ and all CN3-port functions on Sigma-II and Sigma-III drives.
