Tips

Tip Problem
1 Speed too low
(with reverse operation)
2 Speed too low
(with continuous operation)
3 Test movement missing
4 No error detected
5 Speed too low and amplitude of
the excitation signal too small
(with reverse operation)
6
Speed too low and
amplitude of the excitation
signal too small
(with continuous operation)
7
Test movement missing
amplitude of the excitation
signal too small
8 amplitude of the excitation si-
gnal too small
9 Following error occurred
*if the travel range is too short, the speed is not increased, as the drive does not
reach the maximum speed.
There are two possibilities to align the analog inputs in the optimization window:

Measures
Increase maximum speed and adapt travel
range*
Increase maximum speed
A test movement is important for drives with
high friction or with mechanical slack points
(play).
Please note the boundary conditions. (see
page 244)
Increase amplitude of the excitation signal;
increase maximum speed and adapt travel
range*
Increase amplitude of the excitation signal;
increase maximum speed.
Increase amplitude of the excitation signal
or / and
activate an appropriate test movement
Increase the amplitude of the excitation si-
gnal.
Increase the parameter "permissible follo-
wing error" or decrease the amplitude of the
excitation signal.
