Caution Messages for Operating Procedures

!Caution The heat sink fins will have a high temperature. Be careful not to touch them.

!Caution The operation of the inverter can be easily changed from low speed to high

!Caution If you operate a motor at a frequency higher than the inverter standard default

The previous material in Chapter 3 gave a reference listing of all the program-

mable functions of the inverter. We suggest that you first scan through the list-

ing of inverter functions to fain a general familiarity. This chapter will build on

that knowledge in the following ways:

1. Related functions – Some parameters interact with or depend on the set-

tings in other functions. This chapter lists "required settings" for a program-

mable function to serve as a cross-reference and an aid in showing how

function interacts.

2. Intelligent terminals – Some functions rely on an input signal on a control

logic connector terminal, or generate output signals in other cases.

3. Electrical interfaces – This chapter shows how to make connections be-

tween the inverter and other electrical devices.

4. Auto Tuning Performance – This chapter shows how to perform auto tun-

ing so to achieve good performance of the motor control.

5. Positioning Performance – This chapter shows how to realize simple po-

sitioning by using encoder (PG) feedback.

6. PID Loop Operation – The MX2 has a built-in PID loop that calculates the

optimal inverter output frequency to control an external process. This

chapter shows the parameters and input/output terminals associated with

PID loop operation.

7. Multiple motors – A single MX2 inverter may be used with two or more

motors in some types of applications. This chapter shows the electrical

connections and inverter parameters involved in multiple-motor applica-

tions.

The topics in this chapter can help you decide the features that are impor-

tant to your application, and how to use them. The basic installation cov-

ered in Chapter 2 concluded with the powerup test and running the motor.

Now, this chapter starts from that point and shows how to make the inverter

part of a larger control or automation system.

Before continuing, please read the following Caution messages.

Otherwise, there is the danger of getting burned.

speed. Be sure to check the capability and limitations of the motor and

machine before operating the inverter. Otherwise, it may cause injury to per-

setting (50 Hz/60 Hz), be sure to check the motor and machine specifications

with the respective manufacturer. Only operate the motor at elevated frequen-

cies after getting their approval. Otherwise, there is the danger of equipment

damage.
