16-05  LCD backlight 
Range 
0~7 
Adjust the screen contrast of the digital operator. If it is set to 0, the screen backlight is turned off. 
 
16-07  Copy function selection 
Range 
0: Do not copy parameter 
1: Read inverter parameters and save to the keypad 
2: Write the keypad parameters to inverter 
3: Compare parameters of inverter and keypad 
 
16-08  Selection of allowing reading 
Range 
0: Do not allow to read inverter parameters and save to the keypad 
1: Allow to read inverter parameters and save to the keypad 
 
LCD digital operator with built-in memory (EEPROM) can be used to store and retrieve parameters: 
 
(1) Read: Save inverter parameters to the digital operator (INV → OP). 
(2) Write: Write the parameters from the digital operator to the inverter and save (OP → INV). 
(3) Verify: Compare the inverter parameters against the parameters in the digital operator. 
 
16-07=0: No action 
16-07=1: Read (all parameters are copied from the inverter to the keypad). 
16-07=2: Write (all parameter are copied from the keypad to the inverter). 
16-07=3: Verify (Compare the set value of the inverter to the parameter of the digital operator). 
 
Set 16-08 = 0, to prevent the saved parameter data stored in the digital operator from accidentally being 
overwritten.  
 
When parameter 16-08=0 and the read operation is executed (16-07=1) a warning message of "RDP Read 
Prohibited" will be displayed on the keypad and the read operation is cancelled. 
 
Refer to the following steps for copy function operation. 
 
For the write-in operation requires the following items to match. 
(1) Control method 
(2) Inverter type 
(3)  Inverter rated capacity and voltage 
 
Note: If the data wright in from older version to new version in inverters, please reset power after finishing wright 
in process.
