Example of Wiring for 3-wire Sequential Operation
Stop switch
(NC)
Run switch
(NO)
Run command
(Operates when the run switch is closed.)
Stop command
(Stops when the stop switch is open.)
Forward/Reverse rotation command
(Multi-function input 3)

Sequential input common
Note 1. The default settings of the multi-function inputs are different from the default settings of the
2-wire sequence.
Note 2. When setting a 3-wire sequence, the operation can be started and stopped with an automati-
cally resetting pushbutton switch.
Initialization Example
The following example shows how to initialize parameters with the 2-wire sequence (factory settings).
Key sequence
Display
Explanation
** Main Menu **
Operation
Displays operation mode.
** Main Menu **
Initialize
Displays initialize mode.
Select Language
English
Puts the Unit in initialize mode.
(Select Language display)
3 times
Init Parameters
No Initialize
Displays the Initialize display.
A1-03= 0 ***
No Initialize
Displays the parameter setting for A1-03.
A1-03= 2220
2-wire Initial
Changes the setting to 2-wire Initialization.
Entry Accepted
Writes the new setting.
Init Parameters
No Initialize
Returns to the Initialize display.
S
Write-protect Passwords
Use parameters A1-04 and A1-05 to write-protect the initialize-mode parameters. Parameters A1-01
through A1-03 and A2-01 through A2-32 can be displayed but not changed if the contents of A1-04 and
A1-05 don’t match. These parameters cannot be changed during operation.
To write-protect the initialize-mode parameters, set the password in A1-05 after inputting the desired
values in A1-01 through A1-03 and A2-01 through A2-32. Parameter A1-05 can be displayed by dis-
playing A1-04 and pressing the Menu Key while pressing the Reset Key. (A1-05 can’t be displayed with
the usual key sequences.)
It will be possible to change the initialize-mode parameters again when the password is written to
A1-04.
