This section explains other output signals.
Use these signals according to the application needs, 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 multi-winding drive unit detects errors and the resetting
methods for those errors.
(1) Servo Alarm Output Signal (ALM)
This signal is output when the multi-winding drive unit detects an error.
Type
Output
(2) Alarm Code Output Signals (ALO1, ALO2, and ALO3)
The ON/OFF combination of these signals specifies the type of alarm detected by the multi-winding drive
unit.
Use these signals as required to display the contents of the alarm at the host controller.
For details, refer to 9.1.1 List of Alarms.
Type
Output
(3) Alarm Reset Method
If a servo alarm (ALM) occurs, use one of the following methods to reset the alarm after eliminating the cause
of the alarm.
The /ALM-RST signal will not always reset encoder-related alarms. If an alarm cannot be reset with /ALM-
RST, cycle the control power supply.
5-74
Configure an external circuit so that this alarm output turns OFF the main circuit power
supply to the SERVOPACK and converter whenever an error occurs.

Be sure to eliminate the cause of the alarm before resetting it.
If the alarm is reset and operation continued without eliminating the cause of the alarm, it
may result in damage to the equipment or fire.
