MMS-9065 and MMS-9068 devices with specific numbers of motor data groups and Acquisition Block Length settings can report all data features as 0 values and not send up to date data to the server. This is due to an issue with the MMS-9065 and MMS-9068 application image.
Normally, when the value of motor current is in range of the minimum and maximum working current, motor data features will return correct feature values. When the value of motor current is out of range, most of the motor features will return 0 values while the Rotor Bar Sideband feature will return -100 dB. Due to an issue with the application image, the MMS devices will return out of range data for valid data when configured with specific numbers of motor data groups and Acquisition Block Length settings. For the MMS-9068, see the below table for the combination motor data groups that return out of range data.
To correct this behavior, you can deploy an updated version of the MMS-9065 or MMS-9068 application image, with the below steps.
