Application modules for MOVIDRIVE® compact
System Description
Rotational
positioning • Modulo positioning
A large number of movements have to be controlled in automated conveyor and logistics
applications to transport the material. Linear movements in the form of trolleys or hoists,
and rotary movements via rotary tables play a key role in these applications.
Rotary movements are often synchronized (circular transfer tables); the material is fed
at a specific degree. However, there are also many rotational applications in which the
material should be moved to its destination by the shortest possible route (distance-op-
timized positioning) or in which it is only permitted to move to the target position in a de-
fined direction of rotation (positioning with fixed direction of rotation).
The position axis is represented on a numbered circle from 0° to 360° to meet these
requirements. The actual position is always in this range.
The "modulo positioning" application module accomplishes these tasks using various
operating modes which are selected via binary inputs (16 table positions) or virtual ter-
minals (control via fieldbus, variable positions).
The following operating modes are available for controlling the machine:
• Jog mode
• Teach mode (terminal control only)
• Referencing mode
• Automatic mode with position optimization
• Automatic mode with direction of rotation inhibit (clockwise - counterclockwise)
• Synchronous automatic mode
The "modulo positioning" module offers the following advantages:
• User-friendly user interface
• Only the parameters required for Modulo positioning (number of teeth in the gear
unit, speed) have to be entered
• Guided parameter setting instead of complicated programming
• Monitor mode for optimum diagnosis
• Users do not need any programming experience
• Rapid familiarization with the system
