Choosing a Programming Device

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.
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.
