The Shihlin electric SF-TYPE inverters have been designed with many complex parameterized
functions to meet most of the application requirements from the market. For customers who contact
inverters for the first time, such a complex inverter may cause troubles when using it. So the users
are expected to read each part of this manual carefully so as to master the operating method of the
inverter. In case there is any question, please feel free to contact us.
In Chapter 2 of this manual, all the series and the corresponding specifications of Shihlin electric
SF-TYPE inverters are listed in detail. Section 2-5 guids customers how to install the inverter and
emphasizes on precautions for safety that much attention should be paid to when utilizing the
inverter.
Chapter 3 guides customers how to use the inverter. In Section 3-1, the operating mode of the
inverter is outlined briefly; in Section 3-2, how to use the operation panel is described, and in
Section 3-3, simple operating steps are explained. Chapter 4 explains the functions of each parameter
in detail.
The definitions of terminologies in this manual are as follows:
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 an operation panel, multi-speed terminals, voltage signal or
current signal) is called ‘target frequency’.
• When the motor starts running, the output frequency of the inverter will gradually accelerate to
the target frequency, and finally run steadily at the target frequency. The output frequency at this
time is called ‘steady output frequency’.
2. There are detailed instructions on parameter settings in Chapter 4. In case users 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 the setting
procedure of this parameter, please refer to P.998 in Chapter 4.
3. The ‘operation mode’ and the ‘working mode’ of the operation panel the operating mode
determine the reference source for the target frequency and the signal source for starting. The
Shihlin inverter has totally 9 operating modes. Please refer to Section 3-1 for details. The
operation panel mainly concerns monitoring of numeric values, setting of parameters and setting
of target frequency. The Shihlin operation panel has totally 5 working modes. Please refer to
Section 3-2 for details.
4. The difference between ‘terminal name’ and ‘function name’:
Near the terminals of the control board or the main board, printed letters can be found. These
letters are used to distinguish each terminal, and thus called ‘terminal name’.
For ‘multi-function control terminal’ and ‘multi-function output terminal’, besides the terminal
name, the ‘function name’ is also necessary to be defined. The function name indicates the actual
functions of the terminal.
