Detection Timing
• Detects a SERVOPACK alarm in the alarm control area (normal times).
This bit is not used with the SVA-01A or SVA-02A Modules. It is used to monitor the SVALM
signal at IW††00 bit 0 and requires a ladder logic program in the user application that will
stop the machine (STOP and SERVO OFF commands).
Alarm Processing
• The command that is currently executing will be terminated.
Positioning will be stopped (deceleration to a stop) if a SERVOPACK alarm occurred while the
POSING command is being executed.
• Bit 5 (command error end) of IW††15 (Motion Command Status) will turn ON.
Errors and Causes
• The cause will vary with alarm details. Since alarm details are monitored at IW††24, refer to
the table of SERVOPACK Alarms on the next page.
Action Taken
• Check the SERVOPACK alarm and eliminate the cause of the alarm.
• Reset the alarm.
