Risk of injury in case of vertical or pre-loaded load! The test works with reduced torque, therefore the testing of hanging load or pre-loaded load is not allowed. If possible, The test should be done without coupled load.
| Feedback |
The feedback/motor test page offers a wiring test for the encoder or motor connection.
When the function is started in the current control mode (OPMODE = 2) with an enabled output, the motor slowly begins to turn. The movement is controlled without using the position encoder (U/F mode). The imported encoder position is observed and noted for evaluation purposes only. Using the position data, the encoder resolution, counting direction and encoder connection can be controlled. If the connection of the analog tracks is faulty, encoders that produce both digital as well as analog information (Endat2.1, Hiperface, BiSS-B) may sometimes lose positioning accuracy only. The drive can still be operated without any problems. Depending on the resolution of the encoder system, it can be difficult to detect such wiring errors.
This test function continually reads both the analog (if available) as well as the digital positional information of the encoder and checks the data for plausibility. If deviations occur, the test function tries to identify the cause of the problem.
The following parameters must be input correctly to ensure that the test can be carried out:

Result
The overall result of the test is displayed on this screen. For the individual tests, a green/red LED shows whether the respective test has been successful (green) or unsuccessful (red).
X1 Connector
This display only applies for encoders with analog and digital position measuring (Endat2.1, Hiperface, BiSS-B). Using the recorded positional information, the correlation between the analog and digital tracks is checked. If there is a discrepancy in the positional information, it may have been caused by interchanged X1 lines (sine/ cosine). The test function tries to detect the potential wiring errors and displays the result using the red or green LED.
Feedback – extended encoder information
This display only applies for encoders with analog and digital position measuring (Endat2.1, Hiperface, BiSS-B).

Contains up to 16 ENDAT2.2 encoder diagnose information. Diagnosis data has to be supported by the encoder and by the firmware (5.91 and newer) and configured in the drive (see ASCII command EN22CNFG). The meaning of the transmitted value can be found in the ENDAT encoder documentation delivered by the manufacturer.
Monitoring Information
Contains up to 16 ENDAT2.2 encoder monitoring information. Diagnosis data has to be supported by the encoder and by the firmware and configured in the drive (see ASCII commands EN22CNFG and EN22DCNT).
Additional Information 1
Contains up to 16 ENDAT2.2 encoder additional information 1 (AI1). Diagnosis data has to be supported by the encoder and by the firmware and configured in the drive (see ASCII commands EN22CNFG and EN22A1CNT).
Additional Information 2
Contains up to 16 ENDAT2.2 encoder additional information 2 (AI2). Diagnosis data has to be supported by the encoder and by the firmware and configured in the drive (see ASCII commands EN22CNFG and EN22A2CNT).
This page presents status information, which have been transmitted by the DSL Encoder.
