MFB
(
Motion Function Blocks)
is a library of function blocks integrated in Unity Pro
used to set up motion control in the architectures of drives and servo drives on
CANopen buses:
b
Altivar 312: For asynchronous motors from 0.18 to 15 kW
b
Altivar 71: For synchronous or asynchronous motors from 0.37 to 500 kW
b
Lexium 32: For servo motors from 0.15 to 7 kW
b
Lexium integrated drives ILA/ILE/ILS: For integrated motor drives from 0.10 to
0.35
kW
b
Lexium SD328A: For 3-phase stepper motors from 0,35 to 0,75 kW.
In compliance with PLCopen specifications, the MFB library allows both easy and
flexible motion programming with Unity Pro, as well as axis diagnosis.
In maintenance operations, drives can be replaced quickly and safely thanks to drive
parameter download blocks.-
Setting up drives on the CANopen network is facilitated through
Motion Tree
Manager
organization in the Unity Pro browser, making it easy for users to access
the application drives.
Applications
The features of the
Motion Function Blocks
library are particularly suitable for
machines with independent axes. In the case of these modular/special machines,
MFB function blocks are the perfect solution for controlling single axes. The following
are typical applications for this type of architecture:
b
Automatic storage/removal
b
Material handling
b
Palletizers/depalletizers
b
Conveyors
b
Packaging, simple label application
b
Grouping/ungrouping
b
Adjustment axes in flexible machines, etc.
Functions
The table below lists the function blocks of the MFB library and the drives compatible
with them. The prefix indicates the block family:
b
MC: Function block defined by the Motion Function Blocks PLC Open standard
b
TE: Function block specific to Schneider Electric products
b
Lxm: Function block specific to Lexium servo drives
