(9) Power line frequency synchronization error (FrE)
Source frequency error
FrE
Is the source within the
range from 46 to 54 Hz or
56 to 64 Hz?
Are wires connected to
the AC power supply
detection terminals R1,
S1 and T1?
Any remarkable
waveform distortion in
the source voltage
waveform?
Chattering in the power
supply contactor when the
power is turned ON?
Is the power supply
transformer capacity
too small?
Examine the power
supply system to
satisfy the
specifications.
Change the sequence
so that inductive loads
are disconnected before
the power is turned
OFF.
Replace the contactor
or add a timer in the
sequence circuit for
prevention of chattering.
Connect the converter
to the power supply
satisfying the specified
capacity requirement.
Correct wiring.
Change to another
power supply system.
Converter failure or
malfunction caused by
noise is probable.
Contact FUJI.
