Checking and Clearing of Settings
17.1
Parameter clear / All parameter clear
• Set "1" to Pr.CL Parameter clear or ALLC All parameter clear to initialize the parameter. (The parameter cannot be cleared
when Pr.77 Parameter write selection = "1".)
• Pr.CL does not clear calibration parameters or the terminal function selection parameters.
• Refer to the parameter list on
Operating procedure
1.
Turning ON the power of the inverter
The operation panel is in the monitor mode.
2.
Changing the operation mode
Press the PU/EXT key to choose the PU operation mode. The PU LED turns ON.
3.
Selecting the parameter setting mode
Press the MODE key to choose the parameter setting mode. (The parameter number read previously appears.)
4.
Selecting the parameter
Turn the setting dial or press the UP/DOWN key until "Pr.CL" appears for Parameter clear or "ALLC" for All
parameter clear, and press the SET key. "0" (initial value) appears.
5.
Parameter clear
Turn the setting dial or press the UP/DOWN key to change the value to "1". Press the SET key to confirm the setting.
"1" and "Pr.CL" ("ALLC") are displayed alternately after parameters are cleared.
• Turn the setting dial or press the UP/DOWN key to read another parameter.
• Press the SET key to show the setting again.
• Press the SET key twice to show the next parameter.
Setting
0 Initial display (Parameters are not cleared.)
The settings of parameters except for calibration parameters
1
and terminal function selection parameters are initialized.
NOTE
• "1" and "Er4" are displayed alternately when the operation mode is other than the PU operation mode.
1) Press the PU/EXT key.
The PU LED turns ON, and "1" appears on the monitor. (When Pr.79 ="0" (initial value))
2) Press the SET key to clear the parameter.
• Stop the inverter first. Writing error occurs if parameter clear is attempted while the inverter is running.
• To clear the parameter, the inverter must be in the PU operation mode even if "2" is set to Pr.77.
• For availability of the Parameter clear or All parameter clear operation for each parameter, refer to the parameter list on
465.
