Tips
Tip Problem
Measures
1
Speed too low
(with reverse operation)
Increase maximum speed and adapt travel
range*
2
Speed too low
(with continuous operation)
Increase maximum speed
3
Test movement missing
A test movement is important for drives with
high friction or with mechanical slack points
(play).
4
No error detected
Please note the
boundary conditions.
(see
page 190)
5
Speed too low and amplitude of
the excitation signal too small
(with reverse operation)
Increase amplitude of the excitation signal;
increase maximum speed and adapt travel
range*
6
Speed too low and
amplitude of the excitation
signal too small
(with continuous operation)
Increase amplitude of the excitation signal;
increase maximum speed.
7
Test movement missing
amplitude of the excitation
signal too small
Increase amplitude of the excitation signal
or / and
activate an appropriate test movement
8
amplitude of the excitation
signal too small
Increase the amplitude of the excitation
signal.
9
Following error occurred
Increase the parameter "permissible
following error" or decrease the amplitude of
the excitation signal.
*if the travel range is too short, the speed is not increased, as the drive does not
reach the maximum speed.

Alignment of the analog inputs
In this chapter you can read about:
Offset alignment...............................................................................................................................193
