5-4-2 Sync Manager PDO Assignment Settings
A Sync manager channel consists of several PDOs. The Sync manager PDO assignment objects
describe how these PDOs are related to the Sync Manager.
The number of PDOs is given in sub-index 00 hex of the Sync manager PDO assignment table. In this
table, index 1C12 hex is for RxPDOs and 1C13 hex is for TxPDOs.
The following table is an example of sync manager PDO mapping.
This section describes the contents of fixed PDO mapping for G5-series Servo Drives. This contents
cannot be changed.
The PDO mapping to be used is specified in Sync Manager 2 PDO Assignment (1C12 hex) and Sync
Manager 3 PDO Assignment (1C13 hex).
Some typical examples of RxPDO and TxPDO combinations are provided below.
This object gives the mapping for an application that uses only cyclic synchronous position mode (csp).
Touch probe function is available.
