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 inde-
pendently from each other and have to work together for certain activities. In example
this could be the case in crane applications, where normal loads are operated intently
from each other and which are switched together for heavy loads. To speed up the
switching together process, the Master/Slave Position correction can be used to syn-
chronize the absolute position of the Slave with the absolute position of the Master.
Additionally by using an Offset a relative reference can be set up in the target posi-
tion.
Preparations Master drive
The Master drive must be set up as follows:
TxPDO2 Identifier
TxPDO2 Function
TxPDO2.Long1
Additionally the following parameters must be set according to the electronic gear:
TxPDO1.Long1
1122
TxPDO1 Identifier
TxPDO1 Function
Preparations Slave drive
The Slave drive must be set up as follows:
RxPDO2 Function
Additionally the following parameters must be set according to the electronic gear:
RxPDO1 Function
Source Master position
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.
