Host Command Reference
AI2 : For normal operation the EN
input must be closed (active,
low). Alarm reset occurs when
the input is opened (inactive,
high). This is an edge-triggered
event. If the switch is open
when an alarm is activated no
reset will occur. The input must
be closed and then opened
to reset the alarm. After the
alarm is cleared, the drive will
be enabled when the input is
closed again.
AI3: The EN Input is not used for
Alarm Reset and may be used
as a general purpose input. AI
will be automatically set to 3 if
CM is set to 13, 14, 17, or 18 or
if SI is set to either 1 or 2 after
the AI command is set.
STM24
Drives with Flex I/O allow a second parameter which allows the user to specify the I/O point used as the Alarm
Reset input. Before an I/O point can be used as an Alarm Reset input it must first be configured as an input with
the SD command. See the STM24 Hardware Manual for details of which inputs may be used as the Alarm Reset
input.
Possible uses for the AI command on the
STM24 are as follows (‘n’ denotes the I/O
point to be used):
AI1n: For normal operation the
designated input ‘n’ must be
open (inactive, high). Alarm
reset occurs when the input
is closed (active, low). This
is an edge-triggered event. If
the switch is closed when an
alarm is activated no reset
will occur. The input must be
opened (inactive, high) and then
closed to reset the alarm. The
drive will be enabled when the
input is returned to the opened
state (inactive, high), unless the
SI command has been used
to configure hardware enable
functionality.
AI2n: For normal operation the designated input ‘n’ input must be closed (active, low). Alarm reset occurs
when the designated input is opened (de-energized). This is an edge-triggered event. If the switch is
open when an alarm is activated no reset will occur. The input must be closed (energized) and then
opened to reset the alarm. The drive will be enabled when the input is returned to the closed state
