POINTPOINT
• Set "1" to Pr.CLR Parameter clear, ALL.CL All parameter clear to initialize all parameters. (Parameters 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 page 711 for parameters cleared with this operation.
NOTE
• and are displayed alternately... Why?
- The inverter is not in the PU operation mode.

is lit, and " " appears on the monitor. (When Pr.79 ="0" (initial value))
2)Press to clear the parameter.
• Stop the inverter first. A writing error occurs if a parameter clear is attempted while the inverter is running.
To perform a parameter clear, the inverter must be in the PU operation mode even if "2" is set to Pr.77.
• For availability of parameter clear and all parameter clear for each parameter, refer to the parameter list on page 711.
