Introduction
Standard Evolution and Technology Update
This standard replaces GB/T 10404-2007. The main technical changes include:
- Added a new parameter for rated voltage 6/2V combination
- Clarified the criterion for determining the direction of rotation (from the perspective of the shaft extension end)
- The electrical schematic diagram was changed to a circuit diagram and an output voltage equation
- Added specific requirements for environmental tests such as vibration and salt spray
Core parameter system
| Parameter Type | XFD/XFS Transmitter | XBD/XBS Transformer |
|---|---|---|
| Rated Frequency (Hz) | 400/1000/2000 | |
| Pole pairs | 4-128 (16 specifications) | |
| Rated voltage (V) | 36/26/6 | 12/6 |
Application case: 70-base XFS dual-channel resolver in CNC machine tools, when the precision machine pole pair number is 16P, the electrical error requirement is ≤15"
Accuracy classification system
| Machine model | Pole pairs | Allowable electrical error | ||
|---|---|---|---|---|
| Level 0 | Level I | Level II | ||
| Precision machine | ≤8 | 4.5" | 1'30" | 3' |
| ≥64 | 3" | 5" | 10" | |
| Rough machine | 4-128 | 20'-30' | ||
Key technical requirements
Zero voltage: Rough machine ≤0.5% maximum output voltage, fine machine ≤0.3%
Insulation resistance: Normal temperature ≥50MΩ, high temperature ≥10MΩ, wet heat ≥1MΩ
Life test: 2000 hours (1150±50r/min)
Implementation suggestions
- Pay attention to the matching relationship between the number of pole pairs and the accuracy grade when selecting
- Ensure that the radial runout of the shaft extension is ≤0.02mm during installation
- A phase-sensitive voltmeter (input impedance＞500kΩ) is required for electrical error detection
- The electrical error is allowed to increase by 1.25-1.5 times after environmental testing
