2.14.3: Custom Output Functions
Any of the amplifier’s digital outputs can be set up in a custom configuration to respond to a
combination of events including faults, warnings, and status indications. The output goes active
when one or more of the selected events take place.
Non-Latched and Latched Custom Outputs
Like an amplifier fault, a custom-configured output can be non-latched or latched.
If a non-latched, custom-configured digital output goes active, it goes inactive as soon as the last
of the selected events is cleared.
If a latched output goes active, it remains active until at least one of the following actions has been
taken:
•
power-cycle the +24 Vdc to the amplifier
•
cycle (disable and then enable) an enable input that is configured as
Enables with Clear Faults
or
Enables with Reset
•
access the CME 2
Control Panel
(
) and press
Clear Faults
or
Reset
•
clear faults over the CANopen network
Latching an output does not eliminate the risk of unexpected motion with non-
latched faults.
!
DANGER
Associating a fault with a latched, custom-configured output does not latch the fault
itself. After the cause of a non-latched fault is corrected, the amplifier re-enables
without operator intervention. In this case, motion may re-start unexpectedly.
For more information, see
Clearing Non-Latched Faults (p. 36)
.
Failure to heed this warning can cause equipment damage, injury, or death.
Custom Output Faults
A custom output can be configured to go active in response to any of the amplifier faults described
in
Fault Descriptions (p. 37)
.
Example: Custom Output Fault Handling vs. Overall Fault Handling
A fault on an output is separate from a fault on the amplifier. For instance, suppose:
•
OUT3 has a
Custom
configuration. Only the
Under Voltage
fault condition is selected, and the
output is latched.
•
Under Voltage
is not latched on the
Configure Faults
screen.
An under voltage condition occurs, and the amplifier goes into fault condition, output stages are
disabled, and faults are reported. At the same time, OUT3 goes active.
The under voltage condition is corrected, and:
•
The amplifier fault is cleared. Output stages are enabled.
•
OUT3 remains active.
