Description
External alarm via DI.
Note:
- It is necessary to program DI for "without external
fault".
Current measurement circuit has a value out of the
standards for zero current.
Offset calculation error in the reading of the input
voltage (synchronism).
Alarm of injection of reactive current in the line.
Fault on the Flash Memory Module (MMF-01).
High internal air temperature alarm.
Measured temperature above 75 ºC (167 °F).
Note:
- It can be disabled by setting P0353 = 1 or 3.
Internal air overtemperature fault.
Measured temperature above 80 ºC.
Only one sensor indicates temperature below
-30° C (-22 °F).
Undertemperature fault measured on the IGBT
temperature sensors.
Alarm to replace the fan (P0045 > 50000 hours).
Note:
- It may be disabled by setting P0354 = 0.
Alarm of clock with wrong time.
Pulse feedback fault.
Overtemperature related to
protection.
Alarm of high temperature measured on the
temperature sensor (NTC) of the IGBT of phase U of
book 1. Measured temperature above 110 ºC (230 ºF).
Fault of overtemperature measured
temperature sensor (NTC) of the IGBT of phase U of
book 1. Measured temperature above 115 ºC (239 ºF).
Alarm of high temperature measured on the
temperature sensor (NTC) of IGBT of phase V of
book 1. Measured temperature above 110 ºC (230 ºF).
Fault of overtemperature measured
temperature sensor (NTC) of IGBT of phase V of
book 1. Measured temperature above 115 ºC (239 ºF).
Alarm of high temperature measured on the
temperature sensor (NTC) of IGBT of phase W of
book 1. Measured temperature above 110 ºC (230 ºF).
Fault of overtemperature measured
temperature sensor (NTC) of IGBT of phase W of
book 1. Measured temperature above 115 ºC (239 ºF).
Alarm of high temperature measured on the
temperature sensor (NTC) of IGBT of phase U of
book 2. Measured temperature above 110 ºC (230 ºF).
Troubleshooting and Maintenance
Wiring at the DI1 to DI8 inputs open (programmed
„
for "without external fault").
Defect on internal circuits of the converter.
„
Main contactor closed before the pre-charge is
„
completed.
CPU was reset and the main contactor did not
„
open.
Line voltage too above the rated value.
„
P0180 too low.
„
Flash memory module defective.
„
Flash memory module not well fitted.
„
High ambient temperature around the converter
„
(> 30 °C (86 °F)).
High temperature inside the panel (> 45 °C (113 °F)).
„
Ambient temperature around the converter ≤
„
-30 °C (-22 °F).
Ambient temperature around the converter ≤
„
-30 °C (-22 °F).
Maximum number of the heatsink fan operating
„
hours exceeded.
Necessary to set the date and time in P0194 to
„
P0199
HMI battery low, defective or not installed.
„
Defect on the internal circuits of the converter.
„
Defect on the fiber optic.
„
Defect on cables XC10A, B, C, D or E.
„
IGBT overload High ambient temperature around the converter.
„
Operation with overload.
„
High ambient temperature (> 45 °C (113 °F)) and
„
high output current.
Locked or defective fan.
„
Book heatsink fins too dirty, hindering the air flow.
