In DTC, the reference setting is rpm... can this be altered to using torque as a reference setting? So instead of wanting the motor to drive at "1000 rpm", you tell the motor to run at "50 Nm". If this is possible, what parameter is this? I'm using an ABB drive ACS800 (01 0016 5). People have told me this "should" be possible but I see no settings for it in the firmware manual.
This is what our Drives Specialist had to say. Yes, you can display the actual motor torque in nM or lb-ft on the display, but you must first know the nominal torque of the motor at full load (100%). Then, when setting up the display, it is a matter of scaling the units and adding the correct label. Keep in mind, this is a calculation based on an estimation. If a true torque reading is needed, using a torque flange, or other sensing device may be more accurate.
today i performed an ID run but , unfortunately it tripped on short circuit , when i checked motor after disconnecting delta connection , all winding showing ok and balanced , and cable is ok s well . then how come this short circuit tripping happend ? and i suspect the drive now damaged . I want to ask you .. is there no protecton against short circuit in ABB acs 800 drives ? should the drive damage everytime any short circuit occur in motor or cable ? hope you answer . thanks .
Tengo este mismo variador, estoy controlando un motor trifasico y se supone que ya lo programe para que me invierta el giro. Quiero que de hacía adelante y hacia atrás utilizando un Jockstin. Y no está haciendo la función que deseo. ¿ qué cree que pueda ser ? Algún parámetro que haya introducido mal ?
hi sir, ı have a problem acs880. ı control 12 motor. running the motors when I connect from PC to control panel, ı want to take back up but 6 motors are stopped ,,6 motors contunie run. Why can ı take fault. ı should look Which parameters and if ı can changed the parameters, problem will fix. while motors running, ı want to take the back up.
Bahadir, Here is the response from our Drive's Tech: hi sir, ı have a problem acs880. ı control 12 motor. -You have 12 motors connected to this one vfd? running the motors when I connect from PC to control panel -Using drive composer? , ı want to take back up but 6 motors are stopped ,,6 motors contunie run. -How are you controlling them individually? Are there individual overload relays for each motor? Why can ı take fault. -What fault are you seeing? ı should look Which parameters and if ı can changed the parameters, problem will fix. -You can select "not at default" when in drive composer while motors running, ı want to take the back up. -You can upload to the control panel or do a backup with drive composer while the vfd is running.
You would do this when you want to run the drive in DTC mode. To run in DTC mode, the drive needs to know how the motor behaves, so this is why you would perform and ID run.

Can i perform ID run without motor?
Hey, thank you for the video. However, my id run and motor data seems reset after i restart the system. Is there any setting?

Can I display the actual torque in [Nm] instead of [%] ? (e.g.min 2:52)

Thank you very much. It works!
Why negative torque is showing, ABB Drive, ACS 880 ???

Can you tell me what's wrong with FB14 (memory unit FW load failed) error, how to fix it?
Update the firmware using drive composer
Hello. I want to lock control screen. How to lock. Pleas help me. Sam one changing my set.
ABB ACS 880 is corrupted memory zmu-02 (primary control) then how it works, please help me. Thank you.

Hola Juan Antonio, tu sabes que modelo es este drive para poderlo conectar a 120vAC de la casa?
When we are performing ID run whether real current will be flowing to the motor ?
Yes, current will be flowing to the motor
Dear why need ID Run

-You have 12 motors connected to this one vfd?
running the motors when I connect from PC to control panel
-Using drive composer?
, ı want to take back up but 6 motors are stopped ,,6 motors contunie run.
-How are you controlling them individually? Are there individual overload relays for each motor?
Why can ı take fault.
-What fault are you seeing?
ı should look Which parameters and if ı can changed the parameters, problem will fix.
-You can select "not at default" when in drive composer
while motors running, ı want to take the back up.
-You can upload to the control panel or do a backup with drive composer while the vfd is running.
Why we use ID run option in drive..?
You would do this when you want to run the drive in DTC mode. To run in DTC mode, the drive needs to know how the motor behaves, so this is why you would perform and ID run.
Thank you very much!
Very important solution. ?
I want to konw " remote mode "" motor run
Makasih masehh
Thank you so much
Please give me suggestions and instructions for give run and stop commands of ACS880 over Modbus rtu
thank you so much ..
Hello could you test this software? study circuit solver on the playstore!

Motor should be cool, better uncouple the motor, make rotary ID run,
so vfd will easily detect all required parameters.
