8.2

Example of a drive initialisation with the "CiA402" technology application

Servo Drives 9400 HighLine from software version 7.0 are provided with the "CiA402" CANopen

device profile as technology application. "CiA402" presents a standardised drive behaviour with the

corresponding operating modes and objects.

Drive initialisation
The drive initialisation is carried out by the EtherCAT master and consists of the following parts:

1. Change of the communication status: "Pre-operational"

This is required as the drive can be in any communication status after start-up.

2. Drive identification
3. Initialisation of communication profile objects
4. PDO mapping
5. Initialisation of device profile objects
6. Initialisation of manufacturer-specific objects

After successful initialisation
... the EtherCAT master can carry out a change to the "Operational" communication status. In this

status, the cyclic transmission of the sync telegram from the master and the exchange of process

data via the PDO channel are carried out.
