6.8.1.2 HEDA-Master
You can transmit 4 process values with max. 7 words (one process value per
channel).
The 1st process value (takes 3 words) is reserved for the axis synchronization.
You may choose between:
Process - setpoint position (Object 2000.1)
Process - actual position (Object 2200.2)
Position from external setpoint (object 2020.1)
Signal read in via Analog channel 4 (X11/17 and X1/18), encoder input or step /
direction input in the master.

Attention in the case of a configuration download with master-slave
coupling (electronic gearbox, cam)
Switch Compax3 to currentless before starting the configuration
download: Master and Slave axis
Position from virtual Master (object 2000.2)
You can transmit 3 additional process values with 4 words data max. You can
make your choice between the Compax3 PD objects.
Please use the
coupling objects (see page 412) for axis coupling.
6.8.1.3 HEDA-Slave
The transferred process values can be read and assigned to objects in the
configuration wizard (e.g. array objects) in the HEDA slave.
Objects with appropriate data width (corresponding to the process values read in)
must be assigned.
The 1st process value is used as input process value (object 3920.1: HEDA
SignalProcessing Input) for axis synchronization. The target for the process values
2, 3, 4 can be selected from a list in the configuration wizard.
