Pre-PID Fail Latch
Displayed when pre-PID is operating with
functions set at AP.34
–AP.36. A fault trip occurs
when a controlled variable (PID feedback) is
measured below the set value and the low
feedback continues, as it is treated as a load
fault.
Ext-Brake Latch
Operates when the external brake signal is
provided by the multi-function terminal. Occurs
when the inverter output starting current remains
below the set value at Ad.41. Set either OU.31 or
OU.32 to 35 (BR Control).
Overheat Pre
Alarm
Latch
When the user has set Pr-78 to 2: Free-Run or 3:

IO Board Trip Latch
Displayed when the I/O board or external
communication card is not connected to the
inverter or there is a bad connection.
Displayed when the error code
continues for more than 5 sec.
(‘Errc’ -> ’-rrc’ -> ‘E-rc’ -> ’Er-c’ -> ‘Err-‘ -> ’- -rc’ -
> ‘Er- -‘ -> ’- - - -‘ -> ’Errc’ -> …)
