Jual Inverter Mitsubishi FR-F800

Inverter Mitsubishi FR-F800 Description

Improving starting torque and saving energy at the same time
Advanced optimum excitation control, which has been newly developed,provides a large starting torque while maintaining the motor efficiency under the conventional Optimum excitation control. Without the need of troublesome adjustment of parameters (acceleration/deceleration time, torque boost, etc.), acceleration is done in a short time. Also, energy saving operation with the utmost improved motor efficiency is performed during constant-speed operation. To use Advanced optimum excitation control, set the energy saving control selection parameter (Pr.60) = \”9\” under Advanced magnetic flux vector control.

The offline auto tuning function to measure circuit constants of the motor enables optimal operation of motors even when motor constants vary, when a non-Mitsubishi Electric motor is used, or when the wiring distance is long. Sensorless operation can be performed with Mitsubishi Electric general-purpose (induction) and PM motors (MM-EFS, MM-THE4) as well as non-Mitsubishi Electric general-purpose (induction) and PM motors*. The tuning function enables the Advanced optimum excitation control of non-Mitsubishi Electric general-purpose (induction) motors, which increases the usability in energy saving applications. Depending on the motor characteristics, tuning may not be available.

• With the 24 VDC external power supply, the input MC signal can be turned OFF after the motor is stopped, and turned ON before activating the motor. The inverter enables self power management to reduce standby power.
• The inverter cooling fan can be controlled depending on the temperature of the inverter heatsink. Also, signals can be output in accordance with the inverter cooling fan  operation. When the fan is installed on the enclosure, the enclosure fan can be synchronized with the inverter cooling fan. Extra power consumption when the motor is stopped can be reduced.
