1. Manual Guide
The Shihlin Electric SF-GT Series inverters have been designed with many complex
parameterized functions to meet most of the application requirements in the market. For
first-time users, they may experience some problems while using an inverter of such
complex nature. Therefore, we recommend each user to read through each part of this
manual carefully in order to master the operating methods of the inverters. Please feel free
to contact us if you have any question.
Chapter 3 of this manual lists the detailed specifications of Shihlin Electric SF-GT Series
inverters. Section 3.5 will guide you on how to install the inverters, with an emphasis on
safety precautions that must be noted when using the inverters.
Chapter 4 guides customers on how to use the inverter. In Section 4.1, it gives a brief outline
on the operating mode of the inverter and how to use the operation panel. In section 4.2, the
simple operating steps are explained. Chapter 5 explains the function of each parameter in
detail.
The definitions of terminologies used in this manual are as follow:
1. Output frequency, target frequency, steady output frequency
The actual output current frequency of the inverter is called “output frequency.”
The frequency set by user (through 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.”

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 P.998. For setting procedures of this parameter, please refer to P.998 in Chapter 5.
3.
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 4.1 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 4.1 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.”
