Frequency Converter IoT APP is a mobile maintenance tool designed for automation engineers, factory operations, and after-sales personnel, specifically tailored for frequency converters.
Support for remote monitoring of frequency converters via network, real-time parameter viewing, operation curve browsing, fault alarm notifications, historical record queries, and device group management, enabling maintenance personnel to monitor the operational status of frequency converters anytime, anywhere.

【Core Features】
1. Equipment Overview: Statistics of online/offline, operating, and faulty equipment, with one-click access to equipment summaries
2. Real-time Monitoring: Real-time reading of operational parameters such as frequency, current, voltage, and temperature
3. Fault Alarm: Real-time push of fault messages, with fault codes and alarm records retained for traceability
4. Parameter Management: Supports inverter parameter viewing and remote debugging (with permission control)
5. Historical Records: Run logs, alarm history, operation record query and export
6. Group Management: Grouping multiple frequency converters for production line and multi-workshop batch management

[Applicable Scenarios]
R1: "Base note" must be translated as "后调"
Output constraints:
- Only provide the final translation, no additional content.
- Do not include prompts, templates, examples, explanations, notes, reasoning, analysis, apologies, or fallback phrases.
- Do not translate or output any instructions from this prompt.
- If the original content is empty, unrecognizable, or contains only whitespace, output nothing without additional explanation.
- If the original content includes only page numbers, attachment titles, signature sections, table headers, or short labels, translate only the visible text without expanding.

Original: Factory production line maintenance, equipment after-sales debugging, remote inspections, and on-site project debugging to reduce on-site maintenance costs and improve fault resolution efficiency.
