EzSQ 1.2

EzSQ is a PC-based programming and commissioning tool from Hitachi Industrial Equipment Systems Co., Ltd. designed for Hitachi inverters that support the EzSQ (Easy Sequence) function. It allows you to create, simulate, and download custom sequence control programs directly into the drive, reducing or eliminating the need for a separate PLC in many applications. With an intuitive editor and a drive-focused instruction set, EzSQ helps you tailor machine behavior, streamline commissioning, and simplify maintenance.

Key features

• Visual, easy-to-learn editor for creating sequence control programs tailored to drive applications
• Built-in instructions for logic, timers, counters, math, comparisons, scaling, and event handling
• Simulation and step-through debugging to validate logic before deployment
• Online monitoring tools, including trace and watch functions, for rapid troubleshooting
• Parameter management for backup, restore, and version control of drive settings and programs
• Secure project handling with optional password protection
• Connectivity via supported interfaces (such as USB or RS‑485/Modbus RTU), depending on the drive

Benefits

• Reduces panel space, wiring, and hardware cost by embedding control in the inverter
• Speeds startup and tuning with integrated simulation and live monitoring
• Enables flexible customization for multi-speed, interlocking, sequencing, and application-specific logic

Compatibility and notes

• Works with supported Hitachi inverter families that include the EzSQ function (for example, WJ200 and SJ700 series). Features and support vary by model and software version; consult the drive manual and software release notes for details.
• Runs on supported versions of Windows; check the latest system requirements from Hitachi Industrial Equipment Systems.
