Application modules for MOVIDRIVE® compact
System Description
Positioning
The application modules for the "Positioning" application are suited to all applications
where target positions are specified and movement then takes place to those positions.
Movement can either be linear or rotatory.
For example, trolleys, hoists, gantries, rotary tables, swiveling devices and storage and
retrieval units.
Linear
positioning
In the case of application modules for linear positioning, SEW-EURODRIVE distinguish-
es between whether the movement records are managed in the inverter or the higher-
level PLC.
Movement records
in the inverter
•
Table positioning via terminals
•
Table positioning via fieldbus
These application modules are suited to applications in which movement only has to
take place to a limited number of target positions and in which the highest possible de-
gree of independence from the machine control is required.
Up to 32 movement records can be managed in the inverter in these application mod-
ules. A movement record comprises target position, speed and ramp. The target posi-
tion to which movement is to take place is selected using binary code, by means of the
binary inputs of the inverter or via the virtual terminals (fieldbus, system bus). These ap-
plication modules come with the following features:
•
Up to 32 table positions can be defined and selected.
•
The travel speed can be selected for each positioning movement.
•
The ramp can be set separately for each positioning movement.
•
Software limit switches can be defined and evaluated.
•
Either incremental or absolute encoders can be evaluated.
•
Guided startup and diagnosis.
Four operating modes are available for controlling the machine:
•
Jog mode: The machine can be moved manually.
•
Reference travel: The machine zero is determined automatically for incremental po-
sition measurement.
•
Teach-In: The saved position can be corrected without a programming device.
•
Automatic mode: Higher-level PLC controls the process automatically.
Movement records
in the PLC
•
Positioning via bus
•
Extended positioning via bus
These application modules are suited to applications with a high number of different tar-
get positions.
The movement records are managed in the PLC for these application modules. The tar-
get position and travel speed are specified via the fieldbus or system bus. These appli-
cation modules have the following features:
•
Any number of target positions can be defined and selected via fieldbus / system bus.
•
The travel speed can be selected as required via the fieldbus / system bus for each
positioning movement.
•
Software limit switches can be defined and evaluated.
•
Either incremental or absolute encoders can be evaluated.
•
Straightforward connection to the higher-level controller.
