Hitachi variable frequency drives (inverters) use the latest electronics technology for getting the right AC waveform to the motor at the right time. The benefits are many, including energy savings and higher machine output or productivity. The flexibility required to handle a broad range of applications has required ever more configurable options and parameters — inverters are now a complex industrial automation compo- nent. And this can make a product seem difficult to use, but the goal of this chapter is to make this easier for you.

As the powerup test in Chapter 2 demonstrated, you do not have to program very many parameters to run the motor. In fact, most applications would benefit only from program- ming just a few, specific parameters. This chapter will explain the purpose of each set of parameters, and help you decide which ones are important to your application.

If you are developing a new application for the inverter and a motor, finding the right parameters to change is mostly an exercise in optimization. Therefore, it is OK to begin running the motor with a loosely tuned system. By making specific, individual changes and observing their effects, you can achieve a finely tuned system.

Introduction to Inverter Programming

The front panel keypad is the first and best way to get to know the inverter’s capabilities. Every function or programmable parameter is accessible from the keypad. The other devices simply imitate the keypad’s layout and inverter access, while adding another valuable aspect to the system. In this way, you can use a variety of programming devices with basically the same keypad skills. The following table shows various programming options, the features unique to each device, and the cables required.
