Motor Diagnostics
Provides a set of diagnostic tests for verification of an online encoder and motor.
Opening any Diagnostic window places the drive in a special override mode that
lets wiring and settings to be verified. See
Diagnostic Testing Procedure on
page 3-94 for the diagnostic test procedure. The drive must be re-enabled after
the diagnostic testing is complete.
Commutation Diagnostics
Use the Commutation Diagnostics window to verify motor commutation.
The Commutation Diagnostics window has these parameters, status, and
commands:
IMPORTANT The commutation diagnostics should be performed only when the motor
under test is not connected to a load. The presence of an inertial or
frictional load may cause erroneous test results.
Parameter Description
Test Current The percentage Value for the Test Current.
Note; The value is based on a percentage of the maximum
current rating assigned to the specific motor in the Ultraware
motor database.
Statuses Description
Test Status Indicates the current status of the Commutation Diagnostics.
Possible displays include:
• Idle
• Test in Progress
• Test Success
• Test Failure
Test Results • “ “ (blank), indicates test has not yet been performed.
• Test Aborted by User
• Test Distance Reached
• Marker Found
• Wiring Changes Recommended
• Feedback Resolution Error
• Encoder Alignment Error
Measured Feedback Resolution Displays the Counts/Electrical Cycle recorded during the test.
Expected Feedback Resolution Displays the Counts/Electrical Cycle assigned to the specific
motor in the Ultraware motor database.
