Chapter 5 Detailed Function Introductions
Pb.05 MODBUS frequency reference unit Setting range: 0.1 [0]
0: 0.01Hz 1: 0.1Hz
Notes:
The frequency unit can be selected for the PLC frequency command.
The output frequency resolution rate for this series of frequency inverters is 0.01Hz. When the frequency
command unit of the function code Pb.05 is selected as 0, i.e. 0.01Hz, the given frequency value it receives
will be treated as 0.01Hz directly. If the unit is selected as 1:0.1Hz, it will be converted into 0.10Hz internally
automatically. If the frequency command received is 01F4 (16 hexadecimal of 500), when Pb.05 selects 0, it
will be treated as 5.00Hz by the system; when Pb.05 selects 1, it will be converted into 50.0 (0) Hz by the
system automatically.
Pb.06 Selection of MODBUS data storage Setting range: 0.1 [0]
0: Not save to EEPROM 1: Directly save to EEPROM
Notes:
This function code is used to select whether to save the MODBUS data to EEPROM or not. If pb.06 is set as 1,
parameters that modified by MODBUS communication will be saved to EEPROM directly. However, if Pb.06
is set as 0, the modified parameters will not be saved to EEPROM, but stored in RAM and they will be lost
when power is off. The other method to save the data to EEPROM is that write the MODBUS address
corresponding to the modified parameter to 0x00FF, then the data will be saved to EEPROM which acts as the
“ENTER “key to save the data.
Write or erase EEPROM frequently will reduce the life of EEPROM. Write parameter data and save the data
to EEPROM frequently in communication mode is not allowed; for writing data frequently, you must modify
Pb.06 as 0.
Pb.07 CCF6 Fault Handling Setting range:0.1 [0]
0: Not generate fault and keep on running 1: Generate fault and stop
Notes:
This function code is used to decide whether to generate communication fault or not. When the value is 1, if
communication fault occurs, the keypad will display CCF6 and the inverter stop as fault occurs; when the
value is 0, it doesn't generate the fault and the inverter will keep on running.
5.13 Display Control (Group PC)
PC.00 LCD Language selection Setting range: 0.1 [0]
0: Chinese, display Chinese prompt in LCD screen; 1: English, display English prompt in LCD screen.
Notes:
This function is only effective for the keypad equipped with LCD. The LED keypad only displays the segment code
characters or figures.
PC.01 Output frequency (Hz) (Before
compensation)
Setting range: 0.1 [1]
PC.02 Output frequency (Hz) (Actual) Setting range: 0.1 [0]
0: No display 1: Display
Notes:
When PC.01 is set as 1, the output frequency before compensation will be displayed in the monitoring state,
and the indicator light will indicate the unit Hz; if it is set as 0, the output frequency before compensation and
the unit will not be displayed.
When PC.02 is set as 1, the actual output frequency will be displayed in the monitoring state, and the unit is
Hz; if it is set as 0, the target will not be displayed.
PC.03 Output current (A) Setting range: 0.1 [1]
0: No display 1: Display
