Abnormality Diagnosis and Actions
Abnormality during operation sets off alarm or warning. In such cases, please check the
corresponding code and take appropriate actions. When the abnormality is not corrected after
such actions, please contact us at our service department.
11.2 Servo Alarm and Check List
Upon detecting abnormality, the drive sets off the servo alarm, and transitions to servo off status
ad stops. In such case, the stop method follows the set value of the emergency stop setting
(0x2013).
