To allocate an object to a PDO in Sysmac Studio, select
Output
(or
Input
) for one of
1st receive PDO
Mapping
to
5th receive PDO Mapping
(or
1st transmit PDO Mapping
to
5th transmit PDO Mapping
),
right-click
Add PDO Entry
on the right side of the screen, and then select a desired object from the list.
When
Output
(or
Input
) is selected, the applicable PDO among
1st receive PDO Mapping
to
5th
receive PDO Mapping
(or
1st transmit PDO Mapping
to
5th transmit PDO Mapping
) will be allocated to
Sync Manager.
Note that up to 5 PDOs can be selected each for the target of
Output
(or
Input
).

In the example shown below,
Jogging Frequency
(Index: 3012.5Dh) and
Manual Torque Boost
Frequency 1
(Index: 3012.62h) are allocated to
1st receive PDO Mapping
.
The PDO free format has the restrictions that are described below.
•
Up to 2 objects can be allocated to each PDO from 1600 to 1604 hex and 1A00 to 1A04 hex. Keep
the total size of the allocated objects to within 4 bytes.
•
Up to 5 PDOs each can be allocated to 1C12 and 1C13.
•
An object from 5000 to 5999 cannot be allocated to RxPDO (master to slave) together with an object
from 6000 to 6999.
•
An RxPDO that combines an object from 5000 to 5999 with an object from 6000 to 6999 cannot be
allocated to 1C12 hex of Sync Manager.
•
The inverter parameters (objects 3000 to 3999 and 4000 to 4999) that can be allocated to RxPDO
(master to slave) are limited to those that can be changed during operation.
•
It is not possible to allocate only the LSW or only the MSW to RxPDO or TxPDO.
•
The greater the number of RxPDOs or TxPDOs is, the longer the data updating cycle becomes.
Normally the data is updated every 4 ms, but it can increase to every 6 ms depending on the number.
