08 Warnings and Error Codes | REG2000
8-5
10
ovS
ov at stop
Fault
Over-voltage occurs in the Ready status or the Run status, or hardware
circuit error occurs in voltage detection.
Corrective Action

Check that the input voltage is in the Power Regenerative Unit voltage
rated range, and monitor for voltage surges.

If there is a voltage surge, there may be a phase lead capacitor switch in the
same power supply system that causes an abnormal rise in input voltage.
Press the RESET button after verifying the above items. If the error
message still appears, contact a local dealer near you or Delta to return this
product.
15
OrP
AC Phase lacked
Fault
While regenerating, the three-phase main power loses one or two phases.
Corrective Action

Verify that the mains three-phase voltages are similar.
 Verify that the mains three-phase wiring is correct.
Press the RESET button after verifying the above items. If the error
message still appears, contact a local dealer near you or Delta to return this
product.
16
oH1
IGBT over heat
Fault
The Power Regenerative Unit detects a temperature higher than the
protection level in the power module (see Pr.00-25 in Chapter 07).
Corrective Action
 Check if the ambient temperature is too high.

Check for foreign objects in the heat sink, and if the fan is operating.
 Check that there is enough ventilation space near the Power
Regenerative Unit.
After verifying the above items, stop running the unit, wait for ten minutes,
and then press the RESET button. If the error message still appears,
contact a local dealer near you or Delta to return this product.
17
oH2
HS over heat
Fault
The Power Regenerative Unit detects an internal (air outlet) overheat
higher than the protection level.
(This error message appears only when the air outlet temperature for the
REG370A23A/REG450A43A/REG550A43A models is higher than 80ºC.)
Corrective Action
 Check if the ambient temperature is too high.
 Check for foreign objects in the heat sink, and if the fan is operating.

Check that there is enough ventilation space near the Power
Regenerative Unit.
After verifying the above items, stop running the unit, wait for ten minutes,
and then press the RESET button. If the error message still appears,
contact a local dealer near you or Delta to return this product.
18
tH1o
Thermo 1 open
Fault
The Power Regenerative Unit detects a temperature lower than normal
(lower than -30ºC) at the power module or a circuit error in temperature.
Corrective Action
Increase the temperature and press the RESET button after verifying the
above items. If the error message still appears, contact a local dealer near
