before operation.
4.6.1 Method of operating the keypad panel
(1) Operation process of setting the parameters through keypad panel
A three-level menu structure is adopted for setting the parameters through keypad panel of inverter, which
enables convenient and quick searching and changing of function code parameters.
Three-level menu: Function code group (first-level menu) → Function code (second-level menu) → Set
value of each function code (third-level menu).
(2) Setting the parameters
Setting the parameters correctly is a precondition to give full play of inverter performance. The following
is the introduction on how to set the parameters through keypad panel.
Operating procedures:
① Press the “Fun” key, to enter programming menu.
② Press the key “Stop/Reset”, the DGT lamp goes out. Press ▲ and ▼, the function code will change
within the function code group. The first number behind F displayed on the panel is 1, in other
words, it displays F1××at this moment.
③ Press the key “Stop/Reset” again, the DGT lamp lights up, and the function code will change within
the code group. Press ▲ and ▼ to change the function code to F113; press the “Set” key to display
50.00; while press ▲ and ▼ to change to the need frequency.
④ Press the “Set” key to complete the change.
4.6.2 Switching and displaying of status parameters
Under stopped status or running status, the LED digitron of inverter can display status parameters of the
inverter. Actual parameters displayed can be selected and set through function codes F131 and F132.
Through the “Fun” key, it can switch over repeatedly and display the parameters of stopped status or running
status. The followings are the description of operation method of displaying the parameters under stopped
status and running status.
(1) Switching of the parameters displayed under stopped status
Under stopped status, inverter has five parameters of stopped status, which can be switched over
repeatedly and displayed with the keys “Fun” and “Stop/Reset”. These parameters are displaying: keypad
jogging, target rotary speed, PN voltage, PID feedback value, and temperature. Please refer to the
description of function code F132.
(2) Switching of the parameters displayed under running status
Under running status, eight parameters of running status can be switched over repeatedly and displayed
with the keys “Fun”. These parameters are displaying : output rotary speed, output current, output voltage,
PN voltage, PID feedback value, temperature, count value and linear speed. Please refer to the description
of function code F131.
4.7 Operation process of measuring motor stator resistance parameters
The user shall input the parameters accurately as indicated on the nameplate of the motor prior to selecting
auto torque compensation (F137=3). Inverter will match standard motor stator resistance parameters
according to these parameters indicated on the nameplate. To achieve better control performance, the user
may start the inverter to measure the motor stator resistance parameters, so as to obtain accurate parameters
of the motor controlled.
The stator resistance parameters of the motor can be measured through function code F800.
For example: If the parameters indicated on the nameplate of the motor controlled are as follows: numbers of
motor poles are 4; rated power is 7.5KW; rated voltage is 400V; rated current is 15.4A; rated frequency is
50.00HZ; and rated rotary speed is 1440rpm, operation process of measuring the parameters shall be done as
described in the following:
1. In accordance with the above motor parameters, set the values of F801 to F805 correctly: set the value of
F801 = 7.5, F802 = 400, F803 =15.4, F804 = 4, and F805 = 1440 respectively.
