• Satellite Training Series PART Your First Inverter. • Take the following precautions and use the equipment correctly when practicing and learning the material. The Mitsubishi general-purpose inverter FR-E700 series is used for this training. If the equipment in your actual environment is different, make sure to read the specif- ic manual for your device as operation methods and parameter type differ depend- ing on the specific model of inverter.

Fire prevention This section is specifically about safety matters Do not attempt to install, operate, maintain or inspect the inverter until you have read through the Instruction Manual and appended documents carefully and can use the equipment correctly. • (2) Wiring ● The inverter can be easily set for high-speed operation. Before changing its setting, the performances of the motor and ma- ● Do not install a power factor correction capacitor or surge sup- chine must be fully examined. Pressor/capacitor type filter on the inverter output side.

• This document covers some fundamentals of inverters that first-time users of inverters should know. This document was created on the premise that the Mitsubishi general-purpose inverter FR-E700 series would be used for training.

Before wiring your inverter, make sure to read the related manuals of your products to ensure that you exercise appropriate caution with regards to safety. • 2.1 Mitsubishi general-purpose inverters... 2-2 2.1.1 Lineup...2-2 2.2 Detailed description of the inverter...2-5 2.2.1 Parts identification for the Mitsubishi general-purpose inverter FR-E700 series.2-5 2.3 Connecting the inverter...

While this is not a term often heard in typical conversation, inverters are used in many of the devices used on a daily basis. • 1.1 What is an inverter? 1.1.1 Basic functions of the inverter ◎ Inverter Motors are used to operate many of the devices and products we use on a daily basis. The reason devices do not suddenly start to operate when power switches are turned on is because the inverter controls the speed of motors. • 1.1.3 Familiar examples where inverters are used Belt conveyors used in factories ☆ Improve efficiency of work, braking at specific positions, automatic operation ● The inverter improves efficiency of work and enable conveyors to be stopped at specific positions. ● Conveyor speeds can be optimally adjusted depending on the work conditions.

• Ventilation fans used in buildings ● Pump Damper control ● Fan, blower Damper Switch Standard motor ● Ventilation fan ● Cooling tower ● Drying machine (Furnace fan) Fan, blower Inverter control Inverter Standard motor Fan, blower ☆ The inverter achieves energy efficiency and automation. • Inverters are used in these and many other applications. Electric vehicle Air conditioner Train Washing machine As you can see, inverters are used in the products and devices we use every day. • 1.2 Motor drive force 1.2.1 Motor and frequency Motor speed is changed by varying the frequency of current flowing through motors. Frequency is discussed in more detail in this section. ◎ Frequency Outlets in homes, for example, supply power at 100V/50Hz and 200V/60Hz specifications.

• 1.2.2 Principles of the motor When a motor is connected to a source of power, current flows through the stator winding, or stator coil, within the motor, which creates a rotating magnetic field. This rotating magnetic field causes the stator (rotor) to rotate. Motor speed is proportional to the frequency of the power source. • 1.3 Changing frequency 1.3.1 Structure of the inverter The inverter is generally comprised of 3 sections: converter section, inverter section, and control circuit. ◎ Converter section The converter section converts an AC of an AC power supply into a DC, and then smooths out the pulses of current by the smoothing capacitor. • Mitsubishi general-purpose inverters This chapter introduces several types of actual 'inverters'.
