Page 58: Firmware Update
With the integrated bus interface, the frequency inverter offers the option to update both the firmware of the frequency inverter and the firmware of the integrated bus interface. A firmware update is normally not necessary. In case a FW update is required, please contact the NORD DRIVESYSTEMS service. 4.3 Selecting the operating mode for motor control The NORDAC ON frequency inverter is able to control asynchronous motors.
Page 59 4 Commissioning speed characteristics are recorded and included in the calculation for the motor control. The encoder also allows for the determination of the rotor position, where for the operation of a PMSM the initial value of the rotor position must be additionally determined. This allows for a more precise and faster control of the drive.
