1.3 Definitions of terminologies

Output frequency, target frequency, steady output frequency

The actual output current frequency of inverter is called “output frequency.”

The frequency set by user (via keypad, multi-speed terminals, voltage signal, and current signal or
communication settings) is called “target frequency.”

When motor starts running, inverter output frequency will gradually accelerate to target frequency before it
finally runs steadily at the target frequency. This output frequency is called “steady output frequency.”

Parameter settings

Detail explanation on parameter settings are provided in Chapter 5. For users who are not familiar with these
settings, arbitrary adjustment of the parameter may result in abnormal operations. All parameters can be
reset to their default values by the parameter of 00-02. For setting procedures of this parameter, please refer
to 00-02 in Section 5.1.2

The “operation mode” of the inverter and “working mode” of the keypad

Target frequency command source and start signal source depend on inverter operation mode. There are
nine operating modes in Shihlin inverter. Please refer to Section 4.3 for details.

The keypad is used mainly for monitoring the numeric values, setting parameters and target frequency. There
are 4 working modes on the Shihlin inverter’s keypad. Please refer to Section 4.2 for details.

The difference between “terminal name” and “function name”:

Printed letters can be found near the terminals on control board and main board. They are used to distinguish
each terminal and are called “terminal name.”

For “multi-function control terminal” and “multi-function output terminal,” besides the terminal name, it is also
necessary to define the “function name.” The function name indicates the actual functions of the terminal..

When explaining the function for a terminal, the name used is its “function name”

The difference between “on” and “turn on”:

When describing the function for the “multi-function digital input terminal”, two words “on” and “turn on” are
often used:

The word “on” is used to indicate that the external switch of the terminal is in close state, and thus it belongs
to the description of the state.

The word “turn on” is used to describe the action that the external switch of the terminal is shut from the open
state to the close state, and thus belongs to the description of action. Similarly, the words “off” and “turn off"
belong to the above-mentioned states and actions.
