11.6.2 Axle Positioning
For axle positioning a feedback system is mandatory. In most cases, an expansion
module for the feedback evaluation is needed as well.. An optional expansion module
and operating modes 1004 and 1104 for parameter
Operation mode speed sensor 2
493 enable the evaluation of a speed sensor signal with reference impulse. The ad-
justment of this parameter is described in the manual of the optional expansion mod-
ule. The positioning is started if a start signal is received and the frequency drops
below an adjustable frequency limit. The machine stops with the selected 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 Reference orientation 469, the angle between the reference point
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
Operation Mode 630 which impresses a starting current
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 activated.
Make sure that the change of the direction of rotation cannot result in
any personal or material damage.
The positioning is started by a start command from a signal source (e.g. digital input)
which must be assigned to the parameter
Start Positioning of Axle 37. The signal
source can be selected from the operation modes for digital inputs described in chap-
ter "Digital Inputs".
The positioning starts on condition that the
Actual Frequency 241 of the output sig-
nal is lower than the value entered in parameter
Positioning Frequency 471. Due to
a stopping behavior, the actual frequency drops below the positioning frequency.

Via the parameter Max. positional error 472, the maximum permissible deviation
from the
Reference orientation 469 can be set.
