The user must provide a suitable external I/O power supply separately
because there is no internal 24V power supply in the servo amplifier.
The use of the photocoupler output signals is described below.

XtraDrive
Form an external circuit so that this alarm output (ALM) turns OFF the
servo amplifier.
State Status Result
ON
Circuit between CN1-31 and 32 is closed, and
CN1-31 is at low level.
Normal state.
OFF
Circuit between CN1-31 and 32 is open, and
CN1-31 is at high level.
Alarm state.
Alarm codes ALO1, ALO2 and ALO3 are output to indicate each alarm
type.
The use of open-collector output signals ALO1, ALO2, and ALO3 is
described below.
Output ALO1 CN1-37 Alarm Code Output
Speed/Torque Control,

These signals output alarm codes to indicate the type of alarm detected
by the servo amplifier. Use these signals to display alarm codes at the
host controller. See
9.2.3 Alarm Display Table
for more on the
relationship between alarm display and alarm code output.
When a servo alarm (ALM) occurs, eliminate the cause of the alarm and
set the following /ALM-RST input signal to high level (ON) to reset the
alarm.
