12.6.2 Axle Positioning

For axle positioning a feedback system is mandatory. In most cases, an expansion
module for the feedback evaluation is needed as well. The operation modes for pa-
rameter
formation on how to set the parameter, refer to the instructions on the optional ex-
pansion module. The positioning is started if a start signal is received and the fre-
quency drops below an adjustable frequency limit. The machine stops with the se-
lected stopping behavior at the entered position angle.
To ensure the correct function of the axle positioning, the speed controller should be
optimized after the guided commissioning. This is described in the chapter "Speed
controller".
Via the parameter
and the required position is entered.
If this value is changed while the machine is at a standstill, the positioning operation
is carried out again at a frequency of 0.5 Hz. For this, a stopping behavior must be
selected for the parameter
either permanently when the drive is at a standstill or for the stopping time (refer to
chapter „Stopping Behavior").

CAUTION
During the positioning operation, the direction of rotation of the drive may change,
regardless of whether the command Start clockwise or Start anticlockwise was acti-
vated.
Make sure that the change of the direction of rotation cannot result in any personal or
material damage.
