In this video, Rick Hillmer walks us through an advanced feature of the ACS880: Motor ID Runs. • ABB’s proprietary Direct torque control algorithm (or DTC) can provide very precise speed and torque control, even at low or no speed without the use of a feedback device. But to do this, the drive needs to know exactly how the motor behaves. So, when running in DTC mode, you must always do some type of motor ID run. The ACS880 has several variations of ID runs. • All drives require motor nameplate data during setup. The ACS880 is no different. After setting all motor nameplate data into group 99 (which is the case for all ABB drives) we will set 99.13 to the preferred ID run method. • If you cannot disconnect your motor from your machine, you can do a “Standstill”. This will only magnetize your motor, but may cause it to rotate slightly. Once you select “standstill” your keypad will display a warning saying that an ID run is about to be performed. With your drive in local control, you can now just press the start button to perform the ID run. This takes about 30 seconds. Once complete, ID run done is displayed. You can now proceed with the rest of the drive setup. • The preferred type of ID run for most applications is “Normal”. The motor must be disconnected from its load for this test. My load in this demo case is just this small plastic wheel, so I will leave it on. Again, change parameter 99.13, this time set to “normal”. Then with my drive in local control, I press the start button on the keypad. This starts the ID run, which takes about 90 seconds. First, the motor does not spin while the drive is calculating the required magnetizing current for the motor. This would be the equivalent of a standstill ID run. Once this is done, the motor is accelerated to full speed in the forward direction, then given several different speed settings and torque pulses. You can see the different speeds and current outputs changing by the analog outputs here, or you can go back to the main screen to see the data. When done, the motor stops, id run done is displayed, and the system is ready to go. • Note that if an ID run fails, there is something wrong, usually either with drive limits or motor connections. Check both of these and try again before proceeding. • Check out more on the ACS880 here: https://www.ramcoi.com/abb/acs880-mac... • Visit our Website: • www.ramcoi.com • Connect with us on social media: • / ramcoinnovations • / ramcoinnovation • / ramco-innovations • • LEGAL DISCLAIMER: • While we have made every attempt to ensure that the information provided is accurate and has been obtained from reliable sources, Ramco is not responsible for any errors or omissions, or for the results obtained from the use of this information.
