Output frequency, target frequency, steady output frequency
+ The actual output current frequency of the inverter is called “output frequency.”

+ The frequency set by user ( via operation 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 setting s 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 o f this parameter,

 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.

+ 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 Sh ihlin operation panel .

 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 ter minal 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 termin al.

+ 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.
