GUI Composer "SpinTAC 1:Startup" tab, Status Not Identified: 2004 (Motor Identification was passed)

Other Parts Discussed in Thread: TMDSHVMTRINSPIN, MOTORWARE


Hello,
I had success to connect the motor TZA-01 (3~ 380V, 50Hz, 0.5kW, 1A, 1100 RPM) to TMDSHVMTRINSPIN and evaluated the InstaSPIN-MOTION. I followed the "QSG: Evaluating InstaSPIN-MOTION (F2806xM) using the Graphical User Interface". I did almost everything (except the Field Control & Modulation Tab). I was quite happy with the result (only I needed to face that DC fan attached to TMDSHVMTRINSPIN was really noisy - too noisy, I felt sorry about that but this was not my main problem).

Then I connected the other motor RG28S-4DK.4F.AL.
The motor identification was passed, but in SpinTAC 1:Startup, the status was always "Not Identified: 2004". I changed the Iq limit and also lower the speed, but the results were the same.
I did again the motor identification and then went to "SpinTAC 1:Startup", the results were the same.
What could be the problem? Why did it not pass this status?

The specification of the motor RG28S-4DK.4F.AL is:
3~ 400V, 50 Hz, 0.74kW, 1.4A, 1220 RPM

The results of "Motor Identification" can be seen below.



Thanks in advance!

Best regards,
Maria

    Maria,

    If your motor is only 1A you don't need to use the DC fan to cool the IPM. It is only needed when you are near the maximum output of the inverter.

    I see these are both induction motors.  In the case of the 2nd is the standard control (without SpinTAC, just using PI for speed loop) look ok? The first thing is always to insure that the ID'd parameters are reasonable and that FAST appears to give good feedback at several speeds. 

    With SpinTAC there are several enhancements to the Inertia ID test that have been added to the MotorWare projects that are NOT in the GUI.  It may be worth it on this motor to go forward with using the CCS based lab projects and run inertia ID through the CCS project. It is typically a matter of a timeout with the motor not being able to reach the necessary speed in the time alloted by the user.

    I will note that we have seen some troubles with ACI Motor ID with the released versions of MotorWare, but they usually manifest themselves with low voltage ACI or very high power ACI, and they usually fail Motor ID or at least produce obviously incorrect parameters (ultra low inductance, wild flux values).  This doesn't seem to be your problem though.  We are working on the ACI motor ID issue and will have a release later this year to improve the robustness.

    Maria,

    When you see the 2004 error from SpinTAC Inertia Identification it means that the process timed out.  When this happens there are two different cases.  

    1. The motor spun continuously during the process - to solve this challenge you need to reduce the Speed of the inertia identification process.  This will attempt to run the inertia identification at a lower speed.  The value for this speed should be about the rated speed of the motor.

    2. The motor did not initially spin during the inertia identification process - to solve this challenge you need to decrease the Ramp Time of the inertia identification process.  This will apply torque quicker to the motor in order to run the inertia identification process.

    If you have already tried reducing the Speed, I would try reducing the Ramp Time parameter.  Reducing this parameter it really critical for any system where there is high friction or loading.

    Hope this helps!

    Hello Chris and Adam,

    Thank you for the replies.

    I tried the PI Speed Controller today (Speed Profile: Staircase Spin) and it worked fine. I attached the results below (at speed 300 and speed 600):

    For SpinTAC Inertia Identification, I tried to lower the Ramp time (until 1s) and lower the speed (until 10 rpm), the results were the same.

    I have not tried the example project yet. It will take more time.

    If there is new version of Motorware, please give notification.

    Thank you!

    Maria,

    When you run the inertia identification and you see the 2004 error does the motor spin continuously or does the motor not spin at all?

    What value do you set for Iq Limit when attempting the inertia identification?

    Thanks

    Hello Adam,

    When I ran the inertia identification, the motor spun at "Identifying motor" and seemed it tried to stop. Then I saw 2004 error and the motor started to spin continously after this error.

    The Iq was 1.12 A. I have tried to lower it until 0.3A and higher it until 1.4 (the upper limit), the results were the same.
