Inverters-FREQROL-XC Series Other features
Network compatibility
RS-485 communication is supported as standard. With the FR-A8NC communication option, the converter also supports CC-Link communication.
- As power can be monitored during both power driving and regenerative driving, the energy saving effect can be checked any time.
- Monitoring of faults and the voltage of each phase allows you to analyze the fault cause easily.
Large braking force
The power regeneration function (enabled continuously with 100%*1 torque or for 60 seconds with the maximum torque of 150%) offers a large braking force, eliminating the need for brake units.
- *1100% refers to the following values.
Harmonic suppression mode: applicable inverter capacity
Common bus regeneration mode: applicable inverter capacity
Power regeneration mode 2: potential regenerative capacity
Easy wiring of the control circuit
Spring clamp terminals (control circuit terminals)
Spring clamp terminals*2 provide high reliability and easy wiring.
- *2The main circuit terminals are screw terminals.
- Easy wiring
Wiring is completed only by inserting the dedicated blade terminal of each cable. Without using the blade terminal, the loose wires can also be connected using a flathead screwdriver. - High reliability
Internal terminal contacts are spring-type. Therefore, wires can be protected against loosening or contact faults due to vibrations during operation on a bogie or during transport. - Maintenance-free
No additional screw tightening is required.
Long life components and life check function
Long life components
- The service life of the cooling fans is designed for 10 years*3.
- The capacitors' life is also designed for 10 years*3*4
- Estimated service lifespan of the long-life parts
| Components | Estimated lifespan | Guideline of JEMA*5 |
|---|---|---|
| Cooling fan | 10 years | 2 to 3 years |
| Main circuit smoothing capacitor | 10 years | 5 years |
| Printed board smoothing capacitor | 10 years | 5 years |
Life check function
- The remaining lifetime can be estimated for wear and tear parts (main circuit capacitor, cooling fan) and inrush current limit circuit by checking the deterioration.
- Using the self-diagnosis function, the part life warning can be output*6 to prevent a fault.
- Estimated service lifespan of the long-life parts
- *3Surrounding air temperature: Annual average of 40℃ (free from corrosive gas, flammable gas, oil mist, dust and dirt).
The design life is a calculated value and is not a guaranteed product life. - *4Input current: 80% of the converter rating
- *5Excerpts from "Periodic check of the transistorized inverter" of JEMA (Japan Electrical Manufacturer's Association).
- *6A warning is output when any of the control circuit capacitors, inrush current limit circuit, and cooling fan reaches its output level.
Protection against hazardous environments
The FR-XC series converters with circuit board coating (IEC 60721-3-3:1994 3C2/3S2) and plated conductors are available for improved environmental resistance. (The converter model name ends with "-60" or "-06".)
Global compatibility
- The FR-XC converter is compliant with UL, cUL, EC Directives (CE marking), and Radio Waves Act (South Korea, KC marking). It is also certified as compliant with the Eurasian Conformity (EAC).
- The converter is compliant with the EU RoHS Directive (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment), friendly to people and to the environment.
Installation inside the enclosure Option
The 30K converter or lower can be installed inside the enclosure by using the optional installation attachment FR-XCCP (the 37K and 55K converters do not need the attachment for installation in the enclosure).
IP20 compliant protective structure Option
The 37K and 55K converters can have the IP20-compliant protective structure when the optional IP20 compatible attachment FR-XCCU is attached.
