Error is detected in the cooling fan with Pr.79 set to 0.
The pre-PID functions set with AP.34 ~ AP.36 remain out
of range (% and time) based on the PID feedback signal.
It is treated as a load fault.
When controlling an external (electro-mechanical) brake,
the inverter output current (Brake Release Current)
remained below the value set at Ad.41. Related
parameter OU.31 or OU.33 set to 35 (BR Control) to
control the relay.
Inverter Overheat. The inverter temperature exceeded
the temperature set in Pr.77. Related parameters Pr.78
set to 2: Free-Run or 3: Dec. OU.31 or OU.33 set to 41
(Pre Overheat).
Protection Functions Related to Communication Options
Lost analog or communications frequency reference.
Based on Pr.12 ~ Pr.15 settings. Related parameters
OU.31 or OU.33 set to 13 (Lost Command).
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 hold error code continues for more
than 5 sec.
(‘Errc’ -> ’-rrc’ -> ‘E-rc’ -> ’Er-c’ -> ‘Err-‘ -> ’- -rc’ -> ‘Er- -‘ -
> ’- - - -‘ -> ’Errc’ -> …)
Communication error is detected between the inverter
and the installed communication board.
