List of fault messages
SCREEN DESCRIPTION
- The equipment is operative. No fault is present.
Overload. The drive trips when the output current reaches the value
set in parameter Pr.21, exceeding the time limit set in parameter
Pr.22. The protection is operative if the parameter Pr.20 has been
set with a value different to 0 ‘NONE’.
Underload. The motor is working with insufficient load. The drive
trips when its current is within the values set in parameter Pr.29 and
Pr.30 exceeding the time limit set in parameter Pr.28. The protection
will be enabled if the parameter Pr.27 has been set with a value
differ
ent to 0 ‘NONE’.
Inverter Overload. The drive cuts the output supply when the
output current exceeds the value set in the corresponding
parameters (150% for 1 minute, 200% for 3 seconds of the drive
rated current). Protection is based on drive rated capacity, and may
vary depending on the device capacity.
E-Thermal. The internal thermo-electronic protection determines
the motor overheating. If the motor is overheated, the drive stops its
output. The protection is enabled setting the parameter Pr.40 to a
value different than 0 ‘NONE’.
Ground Fault. The drive trips when an earth leakage and its current
exceed the internal value configured in the drive. The overload
protection function will protect the drive from any ground fault
caused by a small leakage resistance.
Output Ph Loss. One of the three output phases is open. The
protection will be enabled if the parameter Pr.5 is set as 1 ‘OUTPUT’
or 3 ‘ALL’.
Input Ph Loss One of the three input phases is open. The
protection will be enabled if the parameter Pr.5 is set as 2 ‘INPUT’
or 3 ‘ALL’.
