9.1 Error Messages and Error Handling
Cause or Necessary action
The voltage of the DC power supply in the
power unit is excessive. This may occur
when the power flows back from the load.
The voltage of the DC power supply in the
power unit is insufficient, or see the notes in
"9.1.3, Operation procedure." This may
occur when the overload output activated
the protection function on the DC power
supply.
The temperature in the power unit is
abnormally high. Check if the ambient
temperature is appropriate. Check the filters
for clogging. For filter cleaning, see 10.2.
The sensing voltage is abnormal. Make sure
the cable is properly connected to the
sensing input terminal.
The frequency went out of the
synchronizable range, and thus the output
turned off.
The RMS current limiter was activated, and
thus the output was turned off according to
the setting.
The peak current limiter was activated, and
thus the output was turned off according to
the setting.
This is a power unit internal error. If it
occurs repeatedly, contact the seller (NF
Corporation or our agent) from whom you
purchased the product.
The active wattage limiter is activated.
The RMS current limiter is activated.
The peak current limiter is activated.
The internal operation differs from that for
ID 64.
The peak current limiter is activated.
The internal operation differs from that for
ID 63.
The power unit energization setting was
updated.
A phase configuration is detected that is
different from the previous one.
The power unit or the system has not been
adjusted.
The adjustment data is abnormal.
A USB memory was inserted.
The USB memory eject operation was
performed, and thus the USB memory can
be removed now.
