 Bit 10: SERVOPACK Synchronized Communications Error
 Bit 11: SERVOPACK Communications Error
 Bit 12: SERVOPACK Communications Timeout Error
Note: This alarm occurs in the SERVOPACK with MECHATROLINK Communications when Module assignment is completed
but the power supply to the SERVOPACK is not turned ON.
 Bit 13: Excessive Absolute Encoder Rotations
Detection Timing
This alarm is detected by the communications control section when MECHATROLINK
communications are synchronized between the Machine Controller and the SERVO-
PACK.
Processing When
Alarm Occurs
The current command is canceled.
Details and Cause Data was not updated properly on either the Machine Controller or the SERVOPACK.
Correction Check the connection of the MECHATROLINK cable, and then reset the alarm.
Detection Timing
This alarm is detected by the communications control section when MECHATROLINK
communications is being performed between the Machine Controller and the SERVO-
PACK.
Processing When
Alarm Occurs • The current command is canceled.
• The SERVOPACK turns OFF the power to the Servomotor.
Details and Cause
MECHATROLINK communications stopped because the cable was disconnected, there
is an error in MECHATROLINK communications (e.g., noise entered the communica-
tions path), the power supply to the SERVOPACK was interrupted, etc.
Correction Check the connection of the MECHATROLINK cable, and then reset the alarm.
Detection Timing
This alarm is detected during execution of a motion command.
This alarm is detected by the MECHATROLINK communications control section when
the servo command/response check is performed in the processing sections.
Processing When
Alarm Occurs
The current command is canceled.
Details and Cause
The servo command in MECHATROLINK communications was not completed within
the specified time (5 seconds).
Correction Check for alarms in the SERVOPACK with MECHATROLINK Communications.
Detection Timing
Detection of this alarm is enabled only when an absolute encoder, finite-length axis, and
electronic gear are used. This alarm is detected by the position control section when the
power supply is turned ON.
Processing When
Alarm Occurs The absolute position information that is read from the absolute encoder when the SEN
signal turns ON is ignored.
Details and Cause
An operation error occurred when converting the absolute position information that was
read from the absolute encoder when the power supply was turned ON from pulses to ref-
erence units.
Correction Correct the settings of the gear ratio, encoder pulses, and other related fixed parameters.
