1.8 Number of PDOs that can be set up (channels)

1.8
Number of PDOs that can be set up (channels)
Introduction
PDOs (process data objects) are process data that allow fast, real-time access to selected
data. Mappings have been preconfigured on certain PDOs for certain variables or groups of
variables.
PDOs are, for example, control words such as setpoint velocity, actual velocity, etc.
General procedure
Note
CANopen can monitor up to eight SINAMICS drive objects in the object directory. Max. eight
PDOs can be specified in one SINAMICS drive object.
Note
The SINAMICS drive line-up can manage a maximum of 25 receive and transmit PDOs
(channels) on the CAN bus.
As a maximum of eight PDOs can be specified for each SINAMICS drive object, this means
that at maximum utilization of the created PDOs, a utilization of three SINAMICS drive
objects would be possible. An additional PDO could also be created.
General procedure
Eight PDOs (plus one PDO in one drive object) multiplied by three SINAMICS drive objects -
> max. 25 PDOs (channels).

Send and receive message frames for process data

Introduction
In the SINAMICS drive line-up, the STARTER commissioning tool offers two options for
commissioning a CANopen interface:
1. Via predefined message frames ("predefined connection set") and COB IDs.
2. Via free PDO mapping (user-defined message frames)
In the first step, you are advised to activate the "predefined connection set" and then update
the preconfigured parameters in accordance with your application in the free PDO mapping
process.
Predefined message frames for SINAMICS
The following process data objects are predefined and mapped in the "predefined connection
set" in the receive and transmit message frames for the corresponding drive objects. The
