BONFIGLIOLI Vectron ACTIVE CUBE - Master;Slave Position Correction

11.4.7.1 Master/Slave Position Correction
NOTE
When using this functionality master drive and slave drive have to use the same
mechanical characteristics (i.e. gear transmission ratios) and use the same reference
system.
The Master/Slave Position Correction offers as part of the Electronic Gear the possibil-
ity to synchronize the absolute Position of the Slave to the absolute Position of the
master.
This function is helpful in example in applications, in which drives often work ind
e-
pendently from each other and have to work together for certain activities. In exa
m-
ple this could be the case in crane applications, where normal loads are operated i
n-
tently
from each other and which are switched together for heavy loads. To speed up
the switching together process, the Master/Slave Positi
on correction can be used to
synchronize the absolute position of the Slave with the absolute position of the Ma
s-
ter.
Additionally by using an Offset a relative reference can be set up in the target pos
i-
tion.
Preparations Master drive
The Master drive must be set up as follows:
TxPDO2 Identifier
927 = 640 (or a different not used Identifier)
TxPDO2 Function
932 = 1 – controlled by time or 2 – controlled by SYNC
TxPDO2.Long1
964 = 743 – Act. Position [User Units]
Additionally the following parameters must be set according to the electronic gear:
TxPDO1.Long1
954 corresponding to the description of Master Position
Source
1122
TxPDO1 Identifier
925 = 384 (or a different not used Identifier)
TxPDO1 Function 930 = 1 – controlled by time or 2 – controlled by SYNC
Preparations Slave drive
The Slave drive must be set up as follows:
RxPDO2 Function
926 = 640 (or the Identifier defined in the Master drive)
Additionally the following parameters must be set
according to the electronic gear:
RxPDO1 Function
924 = 384 (or the Identifier defined in the Master drive)
Source Master position
1122 = 11 – RxPDO1.Long
The function Master/Slave Position Correction expects the Target Position [u] always
in RxPD2.Long. When using this function RxPDO2.Long1 and also RxPDO2.Word1,
RxPDO2.Word2, RxPDO2.Boolean1 and RxPDO2.Boolean2 are not allowed to be
used for any other purpose.
