Cause or Necessary action
The adjustment data is abnormal. Cycle the
power. If it still occurs, contact the seller
(NF Corporation or our agent) from whom
you purchased the product.
The power input voltage is excessive. Check
if the power input is appropriate.
The power input voltage is insufficient.
Check if the power input is appropriate.
There is a communication error between the
firmware and the power unit. Cycle the
power. If it still occurs, contact the seller
(NF Corporation or our agent) from whom
you purchased the product.
There is a communication error between the
firmware and the output measurement
section. Cycle the power. If it still occurs,
contact the seller (NF Corporation or our
agent) from whom you purchased the
product.
All power unit versions do not match.
A power unit of unsupported version is
connected.
A multi-phase model is connected with
system cable. Use the multi-phase model as
a single unit.
There is no power unit that can be started.
The output voltage is excessive. This may
occur at an abrupt change in the output
current due to the inductive load.
Also when the remote sensing function set
to FB, check the feedback cable connects
correctly. (See 8.2.2)
The output current RMS value is excessive
on a module in the power unit. This may
occur when the output terminal is
short-circuited.
Also when the remote sensing function set
to FB, check the feedback cable connects
correctly. (See 8.2.2)
The output current peak value is excessive.
The DC power supply in the power unit is
abnormal, or see the notes in "9.1.3,
Operation procedure."
