Motor Test Result Attributes
These are the attributes that are associated with result status applied to a Motion Control Axis.
Motor Test Status
Usage | Access | T | Data Type | Default | Min | Max | Semantics of Values |
|---|---|---|---|---|---|---|---|
Required - D | Get/GSV | USINT | - | - | - | Enumeration: 0 = test process successful 1 = test in progress 2 = test process aborted 3 = test process timed-out 4 = test process faulted 5 = test reached travel limit 6 = reserved 7 = test measurement error 8 = test configuration error 9-127 = reserved 128-255 = vendor specific 128= test prohibited - axis test mode active |
The Motor Test Status attribute returns status of the last Run Motor Test service on the targeted drive axis. The Motor Test Status attribute can be used to determine when the motor test service has successfully completed. Conditions may occur, however, that make it impossible for the drive to properly perform the operation. When this is the case, the test process is automatically terminated and a test error is reported that is stored in the Motor Test Status output parameter. Values in the normal vendor specific range (128-255) correspond to values defined in the vendor-specific range in the open service on the device.
