10.2.5 Position Controller
The position controller evaluates the positioning operation (target/actual position)
and tries to control the drive such that it comes as close as possible to the specifica-
tions. For this purpose, an additional frequency is calcu
lated for compensation of
position deviations. By setting the corresponding parame
ter, this frequency can be
limited. The parameter settings of the position controller determine how quick and
to what extent position deviations are to be compensated.
Via Time Constant 1104, you can define the maximum time in which the position
deviation is to be compensated.
Via parameter
Limitation 1118, you can define to which value the speed is limited
for compensation of the position deviation.

Example:
Position deviates by 1 motor shaft revolution, time constant is set to 1 ms. The pos
i-
tion controller will increase the motor frequency by 1000 Hz in order to compensate
the position deviation. Parameter Limitation 1118 must be set accordingly.
Controller block diagram
In order to avoid oscillations of the drive while it is at standstill, amplification is re-
duced to 50 % of the parameterized value for small position deviations.
