Commissioning Determine the moment of inertia.
step 4
The moment of inertia is set, so that when the motor accelerates to the
maximum speed, no I component is set in the speed controller.

If there is a significant load moment of inertia in actual operation, this
mode)
step should be executed with a coupled load.
For identification runs, the total moment of inertia (P1117 + P1123:8
(from SW 2.4)) is taken into account and corrected in P1117. The
commissioning engineer must make the appropriate distribution
between P1117 and P1123:8 (parameter set independent and
dependent).

!
The motor is accelerated with a positive field direction of rotation up to
the maximum speed along the torque limit.
Carrying–out The step is executed as follows:

P1083 = 4
P1084 = 1
– P1084 = 1 The step was started and is running –
it can be exited with P1084 = 0.
– P1084 = 1/0 The step was successfully completed
– P1084 = –x The step was cancelled with fault–x
(refer to P1084 in Chapter A.1)
Start again after the fault has been removed.
