Also perform an Auto Tuning of the speed controller settings. Auto tuning requires an inertia estimation value. Besides the
settings already described, adjust the following:
Index
5.8.11.1
5.3.2.1
Note:
The recommended setting for parameter 5.3.2.1 Inertia Estimation Mode depends on the torque
characteristic configured with parameter 5.3.3.1 Torque Characteristic. Select Without load profileif there is a constant
torque load, and With profile for a variable torque load.

To start the tuning process, apply a start signal to terminal 13 of the Basic I/O .
Configuring Torque Control
5.5
While the drive is in torque control, the motor speed is monitored but not controlled. Therefore motor speed can reach the speed limits,
when the load, application, or upper system are not within the speed limits. For this reason, it is important to set the limits of the output
frequency as described in 5.4 Configuring Speed
in step 6 of 5.4 Configuring Speed
The procedure is described according to the following wiring diagram.
