Function: Fault
Setting: E
The Fault configured digital output will close whenever the Drive experiences a major fault with the exception of the CPF00
and CPF01 (Digital Operator Communications Faults).
Function: Not Used
Setting: F
The Not Used setting can be used to disable the digital output.
Function: Minor Fault
Setting: 10
A Minor Fault, also referred to as an alarm, indicates that a condition exists that may be critical to the Drive or application but
does not require the Drive to stop. A minor fault will be flashed on the digital operator but neither the Fault output (MA-MB)
nor any digital output configured as a Fault output (H2-0x= E) will close. Any digital output configured as Minor Fault will
close whenever a minor fault of alarm condition exists.
Function: Reset Cmd Active
Setting: 11
A Reset Cmd Active digital output will close to signal that a Fault reset is being attempted from terminals or Serial Com.
Function: Timer Output
Setting: 12
This Timer function, that is built into the Drive, is independent of the rest of the Drive operation, i.e. there is no requirement
for a Run command for the timer to operate. A Timer digital output will close b4-01 seconds after a digital input configured as
Timer Input (H1-0x= 18) closes and remains closed. The Timer digital output will remain closed for b4-02 seconds after the
Timer digital input opens and remains open.
Refer to the descriptions of parameters b4-01 and b4-02 for a timing chart of the Timer function.
