e.g., for machine protection.
5.10.1 Servo Alarm Output Signal (ALM) and Alarm Code Output Signals (ALO1,
ALO2, and ALO3)
This section describes signals that are output when the SERVOPACK detects errors and resetting methods.
(1) Servo Alarm Output Signal (ALM)
This signal is output when the SERVOPACK detects an error.
(2) Alarm Code Output Signals (ALO1, ALO2, and ALO3)
The ON/OFF combination of these signals specifies the type of alarm detected by the SERVOPACK.
