Purchase Channels and Market Information

1. Référence de prix

International market price: Environ 215-230 USD, with discounts for bulk purchases.

2. Warranty Policy

Typically provides a 1-year warranty (based on purchase proof), covering repair or replacement for non-human-induced damage.

Installation and Usage Recommendations

1. Installation Guidelines

Install vertically to ensure heat dissipation, leaving at least 50mm space around. Use cables of specified specifications (par ex., 2.5mm² wires) for main circuit wiring and ensure good grounding.

Control circuit supports source/sink logic switching, directly connectable to PLC or other controllers.

Parameter Settings

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 (recommended 0.1-300 secondes), torque limitation, etc..

Conseils d'entretien

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

If corrosive gases (par ex., 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.
2. Safety Functions: Integrates SIL2/PLd certification for direct use in safety loop design.
3. Diagnostic Technology: Introduces AI fault analysis to shorten downtime.
4. Optimisation de l'efficacité énergétique: Automatically reduces excitation current under light load to enhance energy saving.

Précautions

1. Compatibilité: Confirm that motor parameters (par ex., number of poles, courant nominal) match the frequency converter to avoid overload operation.
2. EMC Compliance: It is recommended to install a filter (par ex., FR-BIF) on the power supply side to reduce electromagnetic interference and comply with local EMC standards.
3. Spare Parts Replacement: When replacing old models (par ex., FR-E720S), pay attention to pin definitions and parameter differences, and contact technical support if necessary.
