Note: When the analog signal (0 to 10 V) input into terminal FR is used as the
motor overheat signal for the PTC thermistor input (FR) (when n141 is
set to 1 or higher), the signal cannot be used as a frequency reference or
for PID feedback. (There are restrictions when setting constants.)
The following settings cannot be set from the Digital Operator. (After
the error is displayed on the Digital Operator, the value returns to the
value before the change.)
If the following settings are set from the MEMOBUS, a constant setting
error will occur. (oP7 will flash on the Digital Operator.)
