(12) Charging circuit error (PbF)
This function is enabled only when 73ANS (73 answerback) is selected using the X1 function.
Charging circuit error
PbF
Is the the output signals of charging
circuit or auxiliary contact of the
magnetic contactor for bypassing
the charging circuit connected to
the
73ANS -assigned digital input (X
terminal)?
Does the auxiliary contact of the
charging circuit magnetic contactor
function within 0.5 sec. after the
charging circuit control output
73A
signal is issued.
*For 280 kW or above capacities:
the auxiliary contact of magnetic
contactor for power supply should
be connected.
Converter failure or
malfunction caused by
noise is probable.
Contact FUJI.
Connect the auxiliary contact to
the digital input. Or if the terminal
is left unconnected, change the
definition of the digital input (X
terminal).
Check the sequence circuit of the
charging circuit magnetic
contactor.

(13) AC input current error (ACE)
AC input current error
ACE
Is there a short circuit or
grounding fault in wiring or
devices in the AC or C
circuit?
Has the load exceeded the
current limit level (H15 to
H18)?
Was there a momentary
power failure?
Correct the short circuit or
grounding fault.
Reset and restart operation.
Or select the "Restart mode
after momentary power
failure" (F02 = 1).
Increase the current limit
level. Or reduce the load or
