13.6.2 Tuning of the motor and the speed controller
The following describes in general how to optimise the speed controller. This may be required
if some parameters have on the load side of the drive system have changed or have not been
set yet, such as:
•
Motor moment of inertia
•
Load moment of inertia
•
Type of coupling between motor moment of inertia and load moment of inertia
Preconditions
All rated motor data is known and set in the inverter, either by selecting the motor from the
motor catalogue or manually.

Required steps
Adapt the following parameters to your drive system using the engineering tool. Since this
only changes load-dependent data, the other parameter groups do not need to be calculated
again.
In the engineering tool, the speed control settings can be confirmed via the Initialise button.
This function is not available via the keypad.
