5.3 Positioning control
5.3.1 Overview
In positioning mode a certain position is set, which is to be approached by the motor. The current
position is derived from the information provided by the internal encoder evaluation. The position
deviation is processed in the position controller and is passed on to the speed controller.
The integrated positioning control allows jerk-limited or time-optimal positioning relative or absolute to
a point of reference. It provides the position controller and - to improve the dynamics - the speed
controller also, with the set points.
In the case of absolute positioning a set target position is directly approached. In the case of relative
positioning a parameterized route is run. The positioning space of 2
32
full revolutions allows any
number of relative positioning in one direction.
The positioning control is parameterized via a target table. The target table includes entries for the
parameterisation of a target via a communication interface and also target positions, which can be
retrieved via the digital inputs. For each entry it is possible to set the positioning method, the driving
profile, the acceleration and the deceleration times as well as the maximum speed. All targets can be
pre-parameterized. The only thing to do for positioning is then to select an entry and start the action. It
is also possible to change the target parameters online via the communication interface.
The servo drive ARS 2300 provides 256 configurable positioning sets.
The following settings are possible for all positioning sets:
 Target position
 Driving speed
 Final speed
 Acceleration

Deceleration
 Torque feed forward

Remaining distance trigger
 Additional flags, these are:

Relative / relative to last target / absolute
 Wait for end / interrupt / ignore start

Synchronized
 Rotary axis

Option: automatic deceleration in case of missing following positioning
 Different options on the setup of path programs
The positioning sets can be activated via all bus systems or via the parameterisation software
Metronix ServoCommander™. The positioning process can be controlled via digital inputs.
