Initialize the Parameters

 How to set again from the beginning or return to the factory default setting?
Q
 How to clear the trip history?
 How to initialize settings other than I/O terminal functions or communication settings?
 After setting "Initialize mode selection [b084]" and "Initialize target selection [b094]", by setting
A
"Execute initialization and mode selection [b180]" to "Initialization (01)", you can clear the trip
history or initialize the parameters and return to the factory default settings.
 "Accumulated RUN time monitor [d016]," "Accumulated power-on time monitor [d017]," "Load
type selection [b049]," "Initialize data selection [b085]," and "Initialize target selection [b094]"
are not initialized.
 EzSQ user parameter U(00) to U(31) ([P100] to [P131]) are initialized only when "Trip history
clear + data initialization + EzSQ program initialization (04)" is selected for "Initialize mode
selection [b084]".

 Set "Initialization execution (01)" to "Execute initialization and mode selection [b180]" and press
!
the SET key. Initialization starts immediately. Note that the data cannot be restored after
initialization.
 When "Display restriction selection [b037]" or "Soft-Lock selection [b031] is set, initialization
cannot be performed because initialization parameters cannot be changed. Release the display
restriction selection or Soft-Lock before initialization.
*1. When "Initialization target selection [b094]" is set to "Initialization of all data except I/O terminals and
basic communication settings (01)", "I/O terminals and basic communication settings" are the
parameters shown in the table below.

*2. Parameters registered in "User Parameter 1 to 32 Selection ([U001] to [U032])" are initialized. [U001] to
[U032] are not initialized.
*3. The setting of " Initialize data selection [b085]" (Pattern 0/Pattern 1/Pattern 3) is determined by the
destination of WJ-C1. Normally, do not change [b085] from the factory-set condition.
For details of the default settings, see "18.2 List of Parameters and Modbus Holding Registers".
