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

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.
