Reference
 If this function is used to detect a disconnection, set the disconnection detection level to the
window comparator upper limit level.
(Normally a bandwidth exceeding the upper limit value is used and once the upper limit value is
breached, a disconnection is detected.)
Frequency Command Source (FREF)
This signal is output when Frequency Reference is set to Digital Operator (A001 = 02).
The signal is turned OFF when Frequency Reference is not set to Digital Operator.
RUN Command Source (REF)
This signal is output when RUN Command is set to Digital Operator (A002 = 02).
The signal is turned OFF when RUN Command is not set to Digital Operator.
