Preparing for Operation
H Example of Wiring for 3-wire Sequential Operation
Stop switch
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
3 times
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.
