Error at Parker 890SD 125kW

By  vdduy253@gmail.com 6 months ago

Dear all,

In my factory have 1 Parker AC890 SD 125kW. Sometimes when it was running. I got the error message : "Desat (Over I)". I also checked about the wiring to motor and motor itself for earth fault but everything look normal. After I reset this fault, the inverter can run normal for a while (maybe few hours, few days or few months) before get this error again.

Anyone know about this fault please let me know how to solve this problem ?

Thank you very much !

    Hello, 

    Have you referenced the manual's definition and possible solutions to this error code for your frame size yet (it refers to Overcurrent)? Found under the "Product Support" tab on the product page for the 890 drives.

    https://ph.parker.com/us/17052/en/ac-variable-frequency-drives-hp-rated-ac890-series

    Desat could be indicative of several things.

    1. Is this a new application, or an existing application (if existing, how old?)
    2. Has it always done this, since the machine was implemented?
    3. Do you ever apply a shock load to the motor?
    4. What are your boost levels?
    5. Can you pinpoint it to one part of operation, that is rarely ever ran?

    Now, this next part may sound odd. But what sort of cabinet/enclosure is it in? If the cabinet/enclosure it is in isn't properly grounded, you may see this rarely (somewhere due to improper grounding, a short occurs when charge instantaneously dissipates off the motor or out of the drive when a large enough potential forms).

    Hi...this type of error appears on the keypad when the drive is unable to distinguish between an overcurrent/desat or overvoltage trip. When does this alarm appear on the keypad? Is it when the drive turns on, a particular point in your process, or is it when a run/jog command is given to the motor?

    Hello Stacy.  If the drive cannot tell the difference, you will generally get a "Stack Trip".  Are you having a similar issue on one of your drives?

    If you have a problem with random "overcurrent" trips , or random disturbance in speed accuracy without tripping, you should change encoder board to at least issue 06.
