2) Contact Output Signal ALM

Output → ALM 1CN-34
Output → ALM-SG 1CN-35
Signal ALM is output when the Servopack detects
an alarm.
Form an external circuit so that this alarm output
(ALM) turns the Servopack OFF.
ON Circuit between 1CN-34 and 1CN-35 is closed.
status: 1CN-34 is at low level.
OFF Circuit between 1CN-34 and 1CN-35 is open.
status: 1CN-34 is at high level.
Alarm codes ALO1, ALO2, and ALO3 are output to indicate each alarm type.

3) Contact Output Signals ALO1, ALO2, and ALO3

Output → ALO1 1CN-30
Output → ALO2 1CN-31
Output → ALO3 1CN-32
Output → SG-AL 1CN-33
These signals output an alarm code to indicate the type of alarm detected by the Servo-
pack.
Use these signals to display alarm codes at the host controller.
NOTE

Using Alarm Codes:

When an alarm is detected, alarm output (ALM) causes the external circuit to turn the
SGDA Servopack OFF. The alarm code remains output for at least 100 ms. For this rea-
son, the host controller must read the alarm code within 100 ms of the alarm occurrence.
When an alarm signal is output, be sure to identify the cause of the problem, take correc-
tive action and operate again. For trouble shooting problems and procedures, refer to 6.2
Troubleshooting.
