4.6 Other Output Signals
This section explains other output signals that are not directly related to any specific control mode.
Use these signals according to the application needs, e.g., for machine protection.
4.6.1 Servo Alarm Output Signal (ALM)
This section describes the ALM signal that is output when the SERVOPACK detects errors and how to reset
the alarm.
(1) Servo Alarm Output Signal (ALM)
This signal is output when the SERVOPACK detects errors.
(2) Alarm Reset Methods
For information on how to reset the servo alarm (ALM), refer to the manual of the connected Command
Option Module.
„ Resetting Alarms from the Host Controller through the Command Option Module
For this method, refer to the manual of the connected Command Option Module.
„ Resetting Alarms Using the Digital Operator
Press the ALARM RESET Key on the digital operator. (Refer to Σ -V Series User’s Manual: Operation of Dig-
ital Operator (SIEP S800000 55).)
4.6.2 Warning Output Signal (/WARN)
This signal is output at occurrence of overload warning (A.910) or regenerative overload warning (A.920) that
may lead to occurrence of overload alarm (A.710) or regenerative overload alarm (A.320). Refer to 8.2.1 List
of Warnings.
(1) Signal Specifications
Note: The /WARN signal must be allocated. For details, refer to 3.3.2 Output Signal Allocation.
Configure an external circuit so that this alarm output turns OFF the main circuit power
