Notifying the generation of an alarm: ALM output
When an alarm generates, the ALM output will turn OFF. At the same time, the ALARM LED on the driver
will start blinking and the motor current will be cut off, causing the motor to stop
∗
. In the case of an
electromagnetic brake motor, the electromagnetic brake will actuate to hold the load in position.
Set the programmable controller to stop the motor operation command upon detection of an OFF status of the
ALM output.
The cause of the generated alarm can be checked by counting the number of times the ALARM LED blinks.
∗ Some alarms do not cut off the current.

Notifying the generation of a warning: WNG output
When a warning generates, the WNG output will turn ON. You can cause a warning to generate prior to a
corresponding alarm. The generation conditions of warnings can be changed using the OPX-2A or MEXE02.

Notifying the content of an alarm using an alarm code: AL0/AL1/AL2
outputs
When the application parameter for alarm code output [APP-1-10] is set to “Enable,” the READY output,
TLC/VLC output and ZSG2/NEAR/ZV output will automatically switch to the AL0 output, AL1 output and
AL2 output, respectively, upon generation of an alarm. The generated alarm can be checked by the ON/OFF
statuses of these signals.
