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

FSP Amplifier
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 Ö ALO1 CN1-37 Alarm Code Output
Speed, Torque, Position
Control, and Programming
Output Ö ALO2 CN1-38 Alarm Code Output
Speed, Torque, Position

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.
