Contact yourYaskawa representative if you cannot solve a problem with the correction given in the table.4.1.3 Resetting Motor Type AlarmsThe SERVOPACK automatically determines the type of motor that is connected to it. If the typeof motor that is connected is changed, an A.070 alarm (Motor Type Change Detected) willoccur the next time the SERVOPACK is started. If an A.070 alarm occurs, you must set theparameters 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.

This utility function is the only way to reset an A.070 alarm (Motor Type Change Detected).The errors are not reset when you reset alarms or turn OFF the power supply to the SER-VOPACK.2. If an A.070 alarm occurs, first set the parameters according to the newly connected motortype and then execute the Reset Motor Type Alarm utility function.Tool Function ReferencePanel Operator Fn021 Operating Procedure with Panel Operator onpage 4-4Digital Operator Fn021 Operating Procedure with Digital Operator onpage 4-4SigmaWin+ Setup − Reset Motor TypeAlarm –Information
