Type Description
➀
User Configurable This type of fault allows you to configure the drive’s response to the
condition that caused the error.
• When configured for a fault, the drive will be stopped, the error condition will
be annunciated on the HIM or a via digital output (if programmed) and the
drive will not be allowed to start until the fault condition is corrected.
• When configured for an alarm, the error condition will be annunciated on the
HIM or via a digital output (if programmed) and the drive will continue to run
and/or be allowed to start.
• When configured for ignore or disabled, the error condition will not be
recognized by the drive or be indicated on the HIM or via a programmed
digital output.
➁
Non-Configurable This type of fault is always enabled and will cause the drive to stop
running in order to protect the drive and/or motor from damage. In
some cases, drive or motor repair may be required. The cause of the
fault must be corrected before the fault can be cleared (via a fault reset
using the HIM or programmed digital input). The fault will be reset on
power up after repair.
Type Description
➀
User Configurable This type of alarm indicates a drive error condition but does not stop
the drive from starting or running. However, if this type of alarm is left
uncorrected, a fault condition may eventually occur.
➁
Non-Configurable This type of alarm is always enabled and will prevent the drive from
starting until the alarm condition is corrected.
