13.6.5 Motor control sengs
13.6.5.1 Speed controller
The speed controller is automacally set when the motor has been selected from the motor

The automacally calculated sengs for the speed controller enable an opmal control
behaviour for typical load requirements.

1.Seng of the gain
Set the proporonal gain V
p
in parameter 0x2900:001.
a) Specify speed setpoint.
b)
Increase parameter unl the drive gets unstable (observe engine noise). 40x2900:001
c)
R
educe parameter unl the drive runs stable again. 40x2900:001
d)
Reduce the parameter to approx. half the value. 40x2900:001
2.Seng of the reset me
Set the reset me T
n
in par
ameter 0x2900:002.
a)
Reduce parameter unl the drive gets unstable (observe engine noise). 40x2900:002
b)
Increase parameter unl the drive runs stable again. 40x2900:002
c)
Increase parameter to approx. double the value. 40x2900:002
3.Seng of the rate me
Set the rate me T
d
in par
ameter 0x2900:003.
a) Increase parameter during operaon unl an opmal control mode is achieved.

Automacally calculated sengs for the speed controller
We recommend a manual
post-opmisaon for the opmal operaon.
The
funcon for automacally calculang the gain and reset me is executed via the parame-
ter 0x2822:014.
The following equaons apply to a "rigid" system.
•
F
or
elasc systems and systems with batches, the determined gain must be reduced.
•
The moment of inera required for the calculaon is the sum of the moment of inera of
the motor and the load mass ineras transformed to the motor side.
