and preventive maintenance support stable system operation.
Real-time monitoring for early fault detection
- Load characteristics fault detection function
When a mechanical fault such as clogging of the filter occurs, the inverter outputs a warning or shuts off the output to prevent system damage.
The speed–torque characteristic is stored while no fault occurs, enabling comparison between the measured data and the stored data.
Supporting scheduled maintenance planning
- Environmental impact diagnosis function
The world's first＊1 “Corrosive-Attack-Level Alert System (CALAS™)”＊2 makes it
possible to identify signs of inverter damage caused by corrosive gas such as hydrogen sulfide＊3. This function notifies operators when factors such as the production environment need to be improved, resulting in reduction in the equipment downtime (for coated models (-60/-06) only).
The combined resistance of multiple metal corrosion sensors is measured to detect the level of degree of metal part corrosion caused by corrosive gas in the air.
- ＊1:According to our investigation as of September 10, 2019.
- ＊2:Patent applied for.
Alert system for the risk of corrosive damage (degree of corrosion) of electrical equipment
- ＊3:Others will be supported in future.
- ＊5:Terminals A, B, and C of the inverter
- Enhanced life diagnosis function
Availability of life diagnosis checks is extended as compared to the FR-E700 series. This enhanced diagnosis function ensures reliable operation of the system.
The design life of cooling fans and capacitors has been extended to 10 years＊4.
- ＊4:Surrounding air temperature: annual average 40°C (free from corrosive gas, flammable gas, oil mist, dust and dirt)
Output current: 80% of the inverter ND rating
Since the design life is a calculated value, it is not a guaranteed value.
Supporting preventive maintenance of peripherals
- Maintenance timer
The Maintenance timer signal is output when the inverter's cumulative energization time reaches the time period set with the parameter. This can be used as a guide for when the maintenance of the equipment should be conducted.
