ID Message Protection
type
Cause or Necessary action
50 Output Overcurrent [RMS] Output Off The output current RMS value is excessive
on a module in the power unit. This may
occur when the output terminal is
short-circuited.
51 Output Overcurrent [Peak] Output Off The output current peak value is excessive.
52 Power Unit DCPS Error Output Off The DC power supply in the power unit is
abnormal, or see the notes in "
8.1.3 ,
Operation procedure."
53 Power Unit DCPS
Overvoltage Output Off The voltage of the DC power supply in the
power unit is excessive. This may occur
when the power flows back from the load.
54 Power Unit DCPS
Undervoltage Output Off The voltage of the DC power supply in the
power unit is insufficient. or see the notes in
"
8.1.3 , Operation procedure." This may
occur when the overload output activated
the protection function on the DC power
supply.
55 Overheat Output Off 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
9.2
.
56 Sensing Voltage Error Output Off The sensing voltage is abnormal. Make sure
the cable is properly connected to the
sensing input terminal.
57 Sync Frequency Error Output Off The frequency went out of the
synchronizable range, and thus the output
turned off.
58 Current Limiter [RMS] Output Off The RMS current limiter was activated, and
thus the output was turned off according to
the setting.
59 Current Limiter [Peak] Output Off The peak current limiter was activated, and
thus the output was turned off according to
the setting.
60 Power Unit Internal Error Output Off 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.
61 Limiting
action The active wattage limiter is activated.
62 Limiting
action The RMS current limiter is activated.
63 Limiting
action The peak current limiter is activated.
The internal operation differs from that for
ID 64.
64 . Limiting
action The peak current limiter is activated.
The internal operation differs from that for
ID 63.
68 PU-ON Setting Updated Message
display only The power unit energization setting was
updated.
