Function Modules
S5-90U/S5-95U
A separate manual is available for the IP 263 positioning module. It can be ordered under the order
number 6ES5 998-5SK21.
The IP 263 is suitable for positioning of two independent axes.
Assignments of Outputs
The IP 263 is a two-channel module: 4 digital outputs are assigned to each channel for the control of
drives;
•
Rapid traverse
•
Creep speed
•
Anti-clockwise rotation
•
Clockwise rotation
Both incremental and absolute encoders (SSI - synchronous serial interface) can be connected for
actual position encoding.
They transmit the machine data, such as
•
Software limit switches
•
Resolution
•
Cutoff difference
•
Switchover difference
•
Zero-speed control
The syntax for the data block which has to be created for this purpose is simple and is described in
the manual.
Positioning
The only thing that remains to be done is to specify the desired target and then the module is ready
for the positioning procedure.
The IP 263 then carries out positioning automatically. When the target has been reached, it sends a
message to the IM 318-B interface module and thus to the CPU.
Figure 16-27 shows the positioning procedure with the IP 263: After the start, a rapid traverse
towards the target takes place first. When the switchover/cutoff point has been reached, a switch-
over to creep speed or cutoff takes place. Afterwards, the IP 263 monitors approach of the target.
When the axis has reached the target range, a signal is sent to the IM 318-B interface module.
