丧失
PID Feedback Reference Lost
A PID feedback reference loss was
detected (b5-12 = 2) and the PID feed-
back input was less than b5-13 (PID
feedback loss detection level) for
longer than the time set in b5-14 (PID
feedback loss detection time).
The settings in b5-13 and b5-14 aren’t
appropriate.
Check the settings in b5-13 and b5-14.
The wiring of the PID feedback cir-
cuit is incorrect.
Fix the wiring.
