Motion Enable Input Open
Bit 5646 (Unlatched Motion Enable Input) is used to indicate when the Motion
Enable input circuit is open. See Figure 32.
Figure 32 Motion Enable Input Fault
If the Motion Enable input circuit is closed and Bit 5646 still shows active, it
indicates that the ACR90x0 may have been damaged by a large reverse
current through the Motion Enable input connector. A large reverse current
can be caused by using the Motion Enable’s 24 V supply to also power
inductive loads—such as brakes, solenoids, contactors, and relays—without
loop-back protection diodes.
If you suspect your ACR90x0 has been damaged, see “Technical
Assistance” on page 3 for information on how to contact the automation
technology center.
See the section “Enable Connection” on page 71 for information on Motion
Enable input connections.
Axis I/O Troubleshooting
Several controller parameters may need additional configuration to work with
different types of drives.
If motion does not occur:
•
Enable input is not connected; see “Enable Connection” on page 71
and “Enable Connector” on pages 52 and 54.
•
The load is jammed; remove power and clear jam.
•
Use the information in the section “Axis Status LED” on page 98 to
determine LED states and methods of resolution.
•
“General Drive I/O” below for drive-function specifics.
