Each motor can only be operated if its field model and the control parameters are correctly set. Using the standard motors and encoders from the motors catalog on the lt-i.com website, a system can be commissioned into operation very quickly and easily.
Third-party motors can also be used however. Since the field models of those motors are not known, the motor must be identified by type or calculated. The selection is made by means of the "Motor data and control settings" dialog box.

Loading a motor data set
Commissioning of a third-party motor
In the case of third-party motors, basic suitability for operation with LTi DRiVES GmbH controllers must first be verified on the basis of the motor data and the data of any installed encoder. The values of the parameters for adaptation of the controller must be determined specifically for each motor by calculation or identification. The difference between the two methods is that when calculating a motor data set the impedances must be taken from the data sheet. In identification the impedances are measured automatically. Each motor can only be operated if its field model and the control parameters are correctly set.
You can obtain the data sets of all standard synchronous motors from the LTi website. On transfer of a standard motor data set the motor name, electrical data and motion mode are loaded. Preset parameters are overwritten. The motor data must then be saved in the device. The motor parameters specified by the manufacturer ensure that a motor can be subjected to load according to its operational characteristic, provided the corresponding power is supplied by the controller.
