Faults
When the drive detects a fault:
• The
digital
operator
displays
text
that
indicates
the specific fault and the ALM indicator LED
remains lit until the fault is reset.
• The fault interrupts drive output and the motor coasts to a stop.
• Depending on the setting, the drive and motor may stop via different methods than listed.
• If a digital output is programmed for fault output (H2-01 = E), it will close if a fault occurs.
When the drive detects a fault, it will remain inoperable until that fault has been reset. Refer to
Fault Reset Methods on page 155.
Minor Faults and
Alarms
When the drive detects an alarm or a minor fault:
• The
digital
operator
displays
text
that
indicates
the specific alarm or minor fault and the ALM
indicator LED flashes.
• The motor does not stop.
• The multi-function contact output closes if set to be tripped by a minor fault (H2-01 = 10), but
not by an alarm.
• The digital operator displays text indicating a specific alarm and ALM indicator LED flashes.
Remove the cause of an alarm or minor fault to automatically reset.
