Additional Information
When using this signal for disconnection detection, set the disconnection detection level to Ana-
log Input [AI1] Detection Upper Limit Level (E157)/Analog Input [AI2] Detection Upper Limit Lev-
el (E160).
(During normal operation, range exceeding the upper limit value is used. If the range falls below
the lower limit value, a disconnection will be detected.)

Frequency Reference Selection Status Signal (FREF)
This signal is output when the frequency reference is set to Operator (Frequency Reference Selection
(F01/C30) = 0, 8), or when the forced operator function (35: OPE terminal) is allocated.
The signal is OFF when the frequency reference is input via other than the Digital Operator
.
