Assigning RxPDO to the sync manager
To assign RxPDO1 to sync manager 2 PDO assignment set the values below to the following
objects:
• Index: 0x1C12
• Sub index: 0x00
• Size: 1
• Value: 1
Setting object 0x1C12, sub-index 0 to a value of 1 (as above) indicates that one RxPDO will be
assigned to the sync manager 2 assignment.
• Index: 0x1C12
• Sub index: 0x01
• Size: 2
• Value: 0x1600
Setting object 0x1C12, sub-index 1 to a value of 0x1600 (as above) maps RxPDO1 to the process
data output sync.
Assigning TxPDO to the sync manager
To assign TxPDO1 to sync manager 3 PDO assignment set the values below to the following
objects:
• Index: 0x1C13
• Sub index: 0x00
• Size: 1
• Value: 1
Setting object 0x1C13, sub-index 0 to a value of 1 (as above) indicates that one TxPDOs will be
assigned to the sync manager 3 assignment.
• Index: 0x1C13
• Sub index: 0x01
• Size: 2
• Value: 0x1A00
Setting object 0x1C13, sub-index 1 to a value of 0x1A00 (as above) maps TxPDO1 to the process
data input sync.
Configuring sync manager 4 and sync manager 5
Similar to the configuration of sync manager 2 and sync manager 3 described above, objects
0x1C14-sync manager 4 PDO assignment (RxPDO) and 0x1C15-sync manager 5 PDO
assignment (TxPDO) are used to assign PDOs to non-synchronized task.
Sync manager 4 and sync manager 5 require support from master (PC/ PLC)side. Depending on
the master, the PDOs assigned to the sync managers may require to be configured to a different
sync unit manually, please refer to the master controller documentation for full details about
configuration at master side.
Download the configuration to the master.
After downloading the configuration to the master the LED(s) on the front of the SI-EtherCAT
should flash, depending on the port(s) connected.
Values written to parameters over RxPDOs should now be viewable using the drive's keypad so
long as the master has put the slave into the operational state; also, parameter values changed
using the drive keypad will be updated on the master.
