Long-life design
● The design life of the cooling fan has been extended to 10 years*1. The life of the fan can be further extended utilizing the it’s ON/OFF control.
● The design life of the capacitors has been extended to 10 years by adopting a capacitor that endures 5000 hours at 105°C surrounding air temperature*1*2.
● Life indication of life components
| Components | Guideline of the FR-E700 Life | Guideline of JEMA*3 |
|---|---|---|
| Cooling fan | 10 years | 2 to 3 years |
| Main circuit smoothing capacitor | 10 years | 5 years |
| Printed board smoothing capacitor | 10 years | 5 years |
- *1 : Surrounding air temperature : annual average 40°C (free from corrosive gas, flammable gas, oil mist, dust and dirt) Since the design life is a calculated value, it is not a guaranteed value.
- *2 : Output current : 80% of the inverter rated current
- *3 : Excerpts from "Periodic check of the transistorized inverter" of JEMA (Japan Electrical Manufacturer’s Association)
Leading life check function
● Degrees of deterioration of main circuit capacitor, control circuit capacitor, and inrush current limit circuit can be monitored.
● Trouble can be avoided with the self-diagnostic alarm*4 that is output when the life span is near.
- *4 : Any one of main circuit capacitor, control circuit capacitor, inrush current limit circuit or cooling fan reaches the output level, an alarm is output. Capacity of the main circuit capacitor can be measured by setting parameter at a stop and turning the power from off to on. Measuring the capacity enables an alarm to be output.
Easy replacement of cooling fan
Combed shaped wiring cover
Removable control terminal block
Wiring of the control circuit when replacing the same series inverter can be done by changing the terminal block.
