P9 ASD Installation and Operation Manual
OP2
Over-Voltage During
Deceleration
• Deceleration time is too short.
• DBR value is too high.
• DBR is required (DBR setup is required).
• Stall protection is disabled.
• 3-phase input voltage is out of specification.
• Input reactance is required.
OP3
Over-Voltage During
Run
• Load fluctuations.
• 3-Phase input voltage is out of specification.
• DBR is required (DBR setup is required).
OT
Over-Torque
• A torque requirement by the load in excess of the setting of
for
a time longer than the setting of
.
• The ASD is improperly matched to the application.
• The load is obstructed.
SEAL
Sealing Water Error
• Inadequate pump seal water.
• Loss of pump seal water.
SOUT
Step-Out
(for PM Motor Only)
• Motor shaft is locked.
• Output phase is open.
• Operating a reciprocating load.
UP1
Main Power
Under-Voltage
• Input 3-phase voltage is too low.
• Momentary power failure longer than the time setting of
UP2
Control Power
Under-Voltage
• This fault is caused by an under-voltage condition at the 5, 15, or the 24 VDC
supply.
• 3-phase input voltage is low.
Note:
The event that caused the trip(s) must be corrected or must decrease to less than the threshold value
required to cause the trip to allow for a Reset to be recognized. In the event of multiple active trips,
the trip displayed will remain until all faults are corrected and cleared.
