Introduction
The basic functions and options of IPOS
plus®
units ensure that the program is no longer
only an open-loop speed controller.
In fact, the positioning and sequence control system integrated in MOVIDRIVE
®
can
often take a great deal of the load off the machine controller (PLC), or maybe even re-
place it.
Reducing the central control offers SEW customers significant potential savings in terms
of hardware and the complexity of electrical installation.
The programming work is divided between the PLC and inverter control. However, users
must familiarize themselves with the system. This includes getting to know IPOS
plus®
if
you want to make effective use its benefits.
3.1.1
Scope of this documentation
The present documentation provides information on the positioning and sequence con-
trol with IPOS
plus®
for MOVIDRIVE
®
B.
With a reduced command set, IPOS
plus®
can also be used in conjunction with the
MOVITRAC
®
B control cabinet inverter and the MQx modules from decentralized tech-
nology. Any deviations regarding the functionality compared to MOVIDRIVE
®
B are
pointed out in the respective technical data in the following sections:
• IPOS
plus®
for MOVITRAC
®
B see (page 118)
• IPOS
plus®
for MQx see (page 120)
First, the manual describes the language-independent functions of IPOS
plus®
.
• Position control
• Position processing
• Task management
• Interrupt management
• IPOS parameters
• IPOS variables
Then, the documentation focuses on the programming in compiler language.
SEW-EURODRIVE recommends that you create new programs in Compiler language.
All MOVIDRIVE
®
B units can be programmed in this language.
Next, the documentation focuses on the programming in assemble language.
The final section describes program examples. It includes an example for beginners with
the basic structure of the state machine of a sequential program. We recommend that
you begin with this basic structure and develop the user program from there.
