1.3 Definitions of terminologies
Output frequency, target frequency, steady output frequency
The actual output current frequency of the inverter is called “output frequency.”
The frequency set by user (viaoperation panel, multi-speed terminals, voltage signal, and current signal or
communication settings) is called “target frequency.”
When the motor starts running, the output frequency of the inverter will gradually accelerate to the target
frequency before it finally runs steadily at the target frequency. This output frequency is called “stead 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 Section5.1.2.
The “operation mode” and “working mode” of the operation panel
The operating mode determines the reference source for the target frequency and the signal source for
starting. A total of nine operating modes are provided in each Shihlin inverter. Please refer to Section 4.3 for
details.
The operation panel is used mainly for monitoring the numeric values, setting parameters and target
frequency. There are a total of five working modes on the Shihlin operation panel. Please refer to Section 4.2
for details.
The difference between “terminal name” and “function name”:
Printed letters can be found near the terminals of either the control board or the main board. They are used to
distinguish each terminal and care 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 explaining the function for the “multi-function control 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.
