3.1 General information
3.1.1 Content of this manual
This user manual illustrates:
• The installation of the DFE24B EtherCAT
®
option card in the MOVIDRIVE
®
MDX61B
drive inverter.
• The use of the DFE24B EtherCAT
®
option card in the MOVITRAC
®
B frequency in-
verter and in the UOH11B gateway housing.
• The startup of the MOVIDRIVE
®
B on the EtherCAT
®
fieldbus system.
• The startup of the MOVITRAC
®
B on the EtherCAT
®
gateway.
• The configuration of the EtherCAT
®
master via XML files.
• The operation of MOVITOOLS
®
MotionStudio via EtherCAT
®
.
3.1.2 Additional documentation
For information on how to connect MOVIDRIVE
®
B simply and effectively to the
EtherCAT
®
fieldbus system, you should request the following documentation on fieldbus
technology in addition to this user manual for the DFE24B EtherCAT
®
option:
• Manual "MOVIDRIVE
®
B Communication and Fieldbus Unit Profile"
•"MOVIDRIVE
®
B" system manual
Apart from describing the fieldbus parameters and the corresponding coding, the
"MOVIDRIVE
®
B Communication and Fieldbus Unit Profile" manual and the
MOVIDRIVE
®
B system manual provide examples to illustrate the different control con-
cepts and possible applications.
3.2 Characteristics
3.2.1 MOVIDRIVE
®
B, MOVITRAC
®
B and EtherCAT
®
The unit behavior of the inverter which forms the basis of EtherCAT
®
operation is re-
ferred to as the unit profile. It is independent of any particular fieldbus and is therefore a
uniform feature. This feature allows the user to develop fieldbus-independent drive ap-
plications. This makes it much easier to change to other bus systems, such as Devi-
ceNet (DFD option).
3.2.2 Access to all information
MOVIDRIVE
®
MDX61B and MOVITRAC
®
B offer digital access to all drive parameters
and functions via the EtherCAT
®
communication interface. The inverter is controlled via
fast, cyclic process data. You can use this process data channel to enter setpoints (e.g.
setpoint speed, ramp generator time for acceleration/deceleration, etc.) and to trigger
various drive functions such as enable, controller inhibit, normal stop, rapid stop, etc. At
the same time you can also use this channel to read back actual values from the in-
verter, such as actual speed, current, unit status, error number or reference signals.
3.2.3 Cyclic data exchange via EtherCAT
®
Process data is usually exchanged cyclically between the EtherCAT
®
master and the
MOVIDRIVE
®
B and MOVITRAC
®
B inverters. The cycle time is specified during the
configuration of the EtherCAT
®
master.
