Yaskawa NSO Option Card Adds Network Safety to AC Drives

Yaskawa has introduced a Network Safety Option Card for selected AC drive families, adding CIP Safety communication over EtherNet/IP. The update matters to machine builders and motor buyers who need to coordinate drive selection with functional safety architecture, commissioning time, wiring layouts and future maintenance access.

Yaskawa NSO Option Card Adds Network Safety to AC Drives

Quick Takeaways

  • Yaskawa says its Network Safety Option Card enables CIP Safety communication over EtherNet/IP for selected AC drive product lines.
  • The card supports GA700, GA800 in the U.S., CR700 and GA500 drive series, according to the company announcement.
  • Supported safety functions include STO and SS1-t, which buyers should match against the required machine safety architecture.
  • For retrofit and new-build projects, the update may affect drive option planning, network layout, commissioning checks and maintenance diagnostics.

Industry Update

Yaskawa Electric Corporation announced a Network Safety Option Card, model JOHB-NSC3-MA, for its AC drive lineup. The company says the option enables CIP Safety communication over EtherNet/IP networks and became available for the listed drive families as of August 31, 2026.

According to Yaskawa, the card supports GA700, GA800 in the U.S., CR700 and GA500 drives. The announcement states that the option provides network-based safety capabilities including STO, or Safe Torque Off, and SS1-t, or Safe Stop 1 with time control.

The company frames the update as a way to reduce separate wiring, engineering work and commissioning time by carrying safety communication over standard industrial Ethernet infrastructure. It also says compatible installed drives can be retrofitted with the option card, depending on the application and drive configuration.

Buyer Considerations

For motor and drive buyers, the practical point is not only the option card itself but the system design around it. A purchasing checklist should confirm the exact drive family, regional availability, firmware or hardware requirements, compatible safety controller, EtherNet/IP network design and the required safety function before specifying the card.

Machine builders should also compare the safety network approach with hardwired safety circuits. Networked safety can reduce wiring complexity, but it shifts more attention to configuration control, diagnostics, validation records and maintenance access for technicians who service the machine later.

For retrofit projects, the announcement is especially relevant when existing AC drives already match the compatible series. Buyers should still verify enclosure space, option-slot availability, documentation, certification requirements and commissioning support before assuming a simple field upgrade.

Frequently Asked Questions

Which Yaskawa drive families are named in the announcement?

Yaskawa names GA700, GA800 in the U.S., CR700 and GA500 drive series as supported families for the Network Safety Option Card.

What safety functions does the card support?

The announcement lists STO, or Safe Torque Off, and SS1-t, or Safe Stop 1 with time control, while buyers should confirm the required safety level and configuration for each machine.

Why does EtherNet/IP safety communication matter for AC drive buyers?

It can reduce separate safety wiring and make safety-device status available on the network, but it also requires careful controller compatibility, setup, validation and maintenance planning.

Can the card be used for existing installed drives?

Yaskawa says the option can be retrofitted to compatible AC drives already installed in the field, so buyers should verify the exact model, option-slot status and local support path.
