Product Description
The modular positioning control system with
IB IL POS 200 enables cost-effective solutions
for many positioning tasks.
The IB IL POS 200 positioning CPU offers
advantages with regard to costs and handling,
especially for the automation of less dynamic
axes with reduction gears, e.g.,
For both functions different detection and output
terminals are available. For this reason the
required interfaces for different sensors and
drives can be combined easily for almost every
positioning task.
–
In transport equipment (conveyor belts,
cranes, chain and monorail conveyors)
This means: Using IB IL POS 200 allows the
automation of up to ten axes for which the
physics for the actual position detection and for
the drive control from axis to axis may vary.
–
In tools (spindles, saw blades, cutting and
bending tools) and for
IB IL POS 200 supports positioning using AC
and DC drives as well as hydraulic drives.
–
For set-up changes (setting of end stops,
guideways or rollers)
The modular structure of the point-to-point
control system allows economic configuration of
any desired number of axes without the
overhead typical for multi-channel control
systems.
The IB IL POS 200 positioning CPU can be used
to create modular and scalable control system
solutions for point-to-point positioning according
to the rapid motion/creeping motion principle. In
combination with I/O terminals from the Inline
automation kit control systems with up to ten
axes can be set up.
IB IL POS 200 performs the control, which is
completed per axis by one Inline terminal each
for position detection and for drive control.

Connection to a PC
The BDM connection is only used for firmware
updates. In this way it is possible to meet future
system requirements by means of updates.
The firmware for the positioning CPU
is transferred upon delivery. In this
way there is no need for programming
except in the case of updates.
A BDM box is required for programming via the
BDM interface. The BDM box includes the
appropriate loader software, which currently can
be run under DOS® or under Microsoft
Windows® 95/98 in a DOS box. Under Microsoft
Windows® NT, the program is downloaded
directly from the software debugger.

Function
Positioning
P o s itio n in g
T a r g e t p o s itio n
S p e e d
The IB IL POS 200 control system switches off
the drives in the target position. This is why in
this case the drives do not provide a torque in
the target position, in contrast to drives of
positioning control systems with position
controllers. This positioning method is used for
applications in which the target position is
retained mechanically (e.g., by a self-sustaining
gear or brake).
S to p p in g p o in t
S ta r t p o s itio n
Positioning occurs in the way that the drive
control is switched from rapid motion to creeping
motion and then to stop at pre-defined positions.
Accuracies of up to ±1 µm can be achieved
depending on the mechanics.
C h a n g in g p o in t
R a p id m o tio n /
c r e e p in g m o tio n
In combination with the position detection
terminals and the terminals for drive control the
IB IL POS 200 positioning CPU enables pointto-point positioning according to the rapid
motion/creeping motion principle. Using
IB IL POS 200 up to ten axes can be set up in a
modular way. The selected rapid motion/
creeping motion method switches off the drives,
which can be run in "rapid motion" and "creeping
motion", when reaching the target position.

Functions in Detail
IB IL POS 200 helps you when creating your
positioning application by means of many
practice-oriented detail functions.
Homing
(Only required for position detection by means of
incremental encoders or sin/cos encoders)
During homing, the zero point signal (Z signal) is
used to synchronize the actual value to a fixed
parameterizable reference point in the
positioning range. One of the hardware limit
switches is used for homing.

Adjusting Value
Error Monitoring and Diagnostics
(Only for incremental encoders)
During positioning the following functions are
monitored:
Homing provides increments for the distance
between the free calibration switch or limit
switch and the zero point of the encoder.
–
Bus diagnostics
–
Drive stop
This eliminates errors (zero point step changes)
during homing.
–
Wrong direction of rotation
–
Z signal (A/B signal) (IB IL INC-IN only)
The adjusting values must be evaluated by the
higher-level control system.
–
Parity of SSI data (IB IL SSI only)
–
Inadmissible parameters or control
commands
–
Overstepping the position of the software
limit switch
–
Reaching the target range
Diagnostics is carried out by means of optical
error messages directly on the appropriate
module and by means of status messages.

Backlash Compensation
Usually, drive systems have clearance, called
"backlash" in practice. Every time the direction
reverses, the backlash causes a motor rotation
without changing the drive position. If the
operating machine forces are only applied to an
axis from one direction clearance compensation
can be achieved by approaching the target
position from the opposite direction.
A
In this way, the IB IL POS 200 positioning CPU
enables position approaching always from the
same direction by means of backlash
compensation. The approach direction is
specified by the home direction. Backlash
compensation must be activated via the
appropriate parameter.

Looping
If the difference between start and target
position is smaller than the sum of start range
and shutdown range it is not possible for pointto-point positioning control systems operating
according to the rapid motion/creeping motion
method to directly approach the target position.
By means of looping the area around the target
is left and then the target position is approached
from a greater distance.
The traversing direction on exiting the target
range is the opposite of the approach direction of
the target position for active backlash
compensation or of the defined approach
direction for looping.
The direction of the loop is determined by the
"Approach direction of the target position for
active backlash compensation or looping"
parameter. A new positioning is carried out
according to the parameterization.
If looping is required to reach the target position,
the terminal executes the process automatically,
provided that looping is enabled. The current
target position is only approached again once
the drive has stopped.
Example
In Figure 9 on page 15, section A, the end
position of the last positioning is the start
position of the following positioning. This start
position is within the sum of the start range and
shutdown range. Therefore it cannot be
approached directly.
The drive must be moved out of the start/
shutdown range using looping. The end point of
this looping is the start position for approaching
the target position (Figure 9 on page 15,
section B).

Looping
Step Operation (A)
Jog Operation (B)
During step operation the axis travels a defined
distance (e.g., in micrometers) in traversing
direction according to the rising edge of the
control bit. Only after finishing step operation a
new edge will be detected. The speed and the
shutdown range can be parameterized for step
operation.
In jog operation the axis travels in traversing
direction as long as the control bit is applied.

Depending on the type of drive there are three
possibilities for dimensioning the control system:
–
For asynchronous motors or pole-reversing
motors digital output modules, type
IB IL 24 DO 4, are used.
–
Using analog modules, type IB IL AO 1/SF,

are converted.
This allows the use of any drives with
variable speeds.
–
For DC motors with brushgear the
IB IL DC AR 48/10A drive controller is used
due to increased demands on speed control
and position accuracy.
All INTERBUS Inline bus terminals
available supporting the PCP protocol
can be used.

Position Detection
Modules IB IL INC-IN or IB IL SSI are used for
position detection. Position and angle
information of position encoders is directly read.
The terminals are configured and parameterized
(encoder data, resolution, etc.) via INTERBUS
and the positioning control system.
The positioning terminals are suitable for all
standard signals. They are designed for
connecting incremental and absolute position
encoders. Both terminals supply the encoder
with 5 V DC and 24 V DC.
After the configuration the desired position
values can be defined via the control program.
The module monitors the positioning and sends
a status message to the control system. When
an error occurs, the drive is stopped
immediately. After configuration via INTERBUS
both terminals operate independent of the bus,
and control system.
Each terminal has three digital inputs with
24 V AC.
Design and Performance of an Inline Positioning Control System
The position accuracy influenced by the control
system is based on the bus cycle time t_bus.
This bus cycle time is currently set to 6 ms.
D e lta _ s [µ m ] =
Example:
In order to achieve a position accuracy of
delta_s = ±10 µm the target must be
approached with the following creeping speed:
v [m /m in ]

Figure 14 Response path until a braking action is initiated after overrunning a limit switch
The response time to an external
event (e.g., limit switch) is four times
the scan time because a constant
delay time (for input, processing,
output) is taken into account.
The traversed distance until a braking action is
initiated after overrunning a limit switch thus is:
s _ re a c t [µ m ] =
v [m /m in ]
· 4 · t_ b u s [µ s ]
