(T) Multi-function input terminal parameters
5.5.1 Input terminal function selection
Use the following parameters to select or change the input terminal functions.
 Input terminal function assignment
• Using Pr.178, Pr.187, and Pr.189 , set the functions of the input terminals.
• Refer to the following table and set the parameters.
*1 The OH signal is activated when the relay contact is open.
NOTE
• The same function can be assigned to two or more terminals. In this case, the logic of terminal input is OR.
• When the terminal assignment is changed with
Pr.178, Pr.187 , or Pr.189 (Input terminal function selection) , wiring may be
mistaken due to different terminal name and signal contents, or may affect other functions. Set parameters after confirming
the function of each terminal.
5.5.2 Operation selection for the external thermal relay
input (Pr.876)
The operation when the external thermal relay input (OH) signal is input can be changed by the Pr.876 setting.
