Initial parameters can be configured via the built-in operation panel (FR-PU07) or FR Configurator2 software, supporting batch writing and AI-assisted debugging.

Typical settings include: motor parameter self-learning, acceleration/deceleration time (推奨 0.1-300 秒), torque limitation, 等.

Maintenance Tips

Regularly clean the cooling fan and filter; replace capacitors every 2 年 (depending on usage environment).

If corrosive gases (例えば, hydrogen sulfide) are detected, improve the installation environment or activate protective measures promptly.

Comparison with Previous Models

Compared with the FR-E700 series, the main upgrades of FR-E820-0.4K-1 include:

1. Communication Capability: New optional Ethernet interface supports next-generation industrial network protocols like CC-Link IE TSN.
