Type Drive Responses to Alarms, Faults, and Errors
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 above.
• If a digital output is programmed for fault output (H2- = 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 247.
Minor Faults
• When the drive detects a minor fault:
• The digital operator displays text that indicates the specific minor fault and the ALM indicator
LED flashes.
• The motor does not stop.
• One of the multi-function contact outputs closes if set to be tripped by a minor fault
•(H2- = 10).
• To reset a minor fault, remove the cause and the drive will automatically reset.
