Improved system safety
Safety standards compliance 
Controls with safety functions can be easily performed. The Safe Torque Off (STO) safety function is supported by the inverter. The inverter with the safety function can comply with the safety standards without incurring much expenses.
● PLd and SIL2 are supported as standard.
- ● EN ISO 13849-1 PLd / Cat.3
- ● EN 61508, EN61800-5-2 SIL2
*1: Safety communication is available between a safety programmable controller and a remote I/O module.
*2: One MC is required to shut off the power at an activation of the protective function.
Reliable and secure maintenance
Standard 24 VDC power supply for the control circuit
In addition to the existing power supply input terminals (R1 and S1) of the control circuit, 24 VDC input is equipped as standard.
The 24 VDC power supplied from outside can be fed to the control circuit locally, enabling the parameter settings, communication operation and safety maintenance without turning ON the main power.
Prevention of trouble with temperature monitoring
The inverter is equipped with an internal temperature sensor, which outputs a signal when the ambient temperature is high.
This facilitates the detection of rises in temperature inside the inverter following cooling fan malfunction, or rises in ambient temperature due to inverter operating conditions.
Long life components and life check function
Long life components
● The service life of the cooling fans is now 10 years*3.
The service life can be further extended by ON/OFF control of the cooling fan.
● Capacitors with a design life of 10 years*3*4 are adapted.
With these capacitors, the service of the inverter is further extended.
● Estimated service lifespan of the long-life parts
| Components | Estimated lifespan of the FR-A800 *3 | Guideline of JEMA *5 |
|---|---|---|
| Cooling fan | 10 years | 2 to 3 years |
| Main circuit smoothing capacitor | 10 years*4 | 5 years |
| Printed board smoothing capacitor | 10 years*4 | 5 years |
- *3 : Surrounding air temperature: Annual average of 40°C (free from corrosive gas, flammable gas, oil mist, dust and dirt).
The design life is a calculated value from the LD rating and is not a guaranteed product life. - *4 : Output current: 80% of the inverter LD rating
- *5 : Excerpts from "Periodic check of the transistorized inverter" of JEMA (Japan Electrical Manufacturer’s Association).
Enhanced life diagnosis function
Quick reaction to troubles
Easy fault diagnosis
● The operating status (output frequency, etc.) immediately before the protection function activates can be stored in the inverter built-in RAM with the trace function. The stored data (trace data) can be copied to a USB memory device or directly imported to a computer, facilitating trouble analysis using the inverter setup software (FR Configurator2).
Trace data stored in the built-in RAM is deleted when the power is turned OFF or the inverter is reset.
● •Clock setting is now available in addition to the already-available cumulative energization time. The time and date at a protective function activation are easily identified. (The clock is reset at power-OFF.) The date and time are also saved with the trace data, making the fault analysis easier.
By using the real-time clock function with the optional liquid crystal display (LCD) operation panel (FR-LU08) (when using battery), the time is not reset even when the power supply is turned OFF.
