  • Page 156 Rotational auto-tuning with the load uncoupled from the motor is strongly recommended whenever possible. Stationary auto- tuning is used whenever it is not possible to disconnect the motor from the load. Rotational and stationary auto-tuning can be selected only when in open loop vector or flux vector control modes (A1-02 = 2 or 3). If terminal resistance auto-tuning is selected, only parameters T1-02 and T1-04 need to be set.
  • Page 157 NOTE: It is possible to a get a “Data Invalid” error if the T1 auto-tuning parameters fall outside the range of what the Drive will accept as reasonable levels for the programmed size of drive (o2-04). If faults are displayed during auto-tuning, check their meanings covered in Chapter 6: Diagnostics and Troubleshooting of the F7 Users Manual (TM.F7.01). Programming 149...
