FR-E700SC-EC inverter
Mitsubishi Electric has introduced the FR-E700SC-EC, a compact inverter that helps to protect personnel and machinery by preventing automatic restart after a stop.
The FR-E700SC-EC also features safe torque off (STO) functionality, which provides protection against unexpected motor start-up according to ISO 13849-1 Category 3/PLd and EN62061/IEC61508 SIL2.
As well as preventing the inverter from automatically restarting, it also disables the drive signal to the motor without turning off the power to the inverter, ensuring that no hazardous motion is possible yet still enabling faster restarts to production after a stoppage.
According to Mitsubishi, the inverter also reduces panel costs and space requirements by removing the need for isolating contactors.
Key features
- Available in two power ranges: 0.1–2.2kW with a single phase, 0.4–15kW with three-phase supplies
- Achieves torques of 150 per cent as low as 1Hz
- Includes USB port that enables connection to a PC
- Incorporates a digital dial that gives users quick access to all important parameters
- Provided with an integrated LED display for system monitoring
- Controlled deceleration after power failures
- Includes built-in RS485 connection with Modbus RTU
- Features plug-in option cards providing connection to CC-Link, Ethernet, Profibus, Devicenet and Lon works
