The causes of and corrections for the alarms are given in the following table. Contact your
Yaskawa representative if you cannot solve a problem with the correction given in the table.
4.1.3 Resetting Motor Type Alarms
The SERVOPACK automatically determines the type of motor that is connected to it. If the type
of motor that is connected is changed, an A.070 alarm (Motor Type Change Detected) will
occur the next time the SERVOPACK is started. If an A.070 alarm occurs, you must set the
parameters to match the new type of motor.
An A.070 alarm is reset by executing the Reset Motor Type Alarm utility function.
This functionality is supported by the following SERVOPACKs.
