LabVIEW FPGA Module NI 9505E Current Loop
Hot-Swap Behavior
The NI 9505E is always disabled when it is inserted in the chassis,
regardless of whether V
SUP
is present or not. You can enable the
drive using the
Enable Drive
method in software. Refer to the
NI 9505 Reference Help
book in the
LabVIEW Help
, available
by selecting
Help»Search the LabVIEW Help
,
for more
information about enabling the drive.
When the NI 9505E is removed from the chassis while it is
enabled, the power to the motor is removed and the motor
decelerates to a stop based on its own friction.
