8.4.1.2 Tuning of the motor and the speed controller
The following describes in general how to opmise 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 inera
•
Load moment of inera
•
Type of coupling between moment of inera of the motor and that of the load
Precondions
•
All rated motor data are known and set in the inverter, either by selecng the motor from
the motor catalogue or manually.
4Motor selecon from motor catalogue ^ 197
4Manual
seng of the motor data ^ 164
•
All further opons for opmisaon have been executed before if possible.
4Automac motor idencaon (energized) ^ 199
4Automac motor calibraon (non-energized) ^ 200
•
Opmisaon is possible online or oine (with or without connected motor).
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 must not be calculated again.
Parameter Name / value range / [default seng] Info

Motor moment of inera
(Motor inera)
0.00 ... [3.70]* ... 20000000.00 kg cm²

Seng of the moment of inera of the motor.

Load moment of inera
(Load inera)

* Default seng depending on the size.
Seng of the moment of inera of the load.
•
Always adjust the seng to the current load, otherwise the opmisa-
on process cannot be executed successfully.

motor and that of the load.
