6.4 DDLM_Set_Prm
When the system is turned ON, configuration data set by the operator is sent to
the absolute encoder by the controller. Parameters transmission depends on the
configuration chosen by the operator. Customarily data is sent automatically
while data setting is carried out through a user's interface available in the
controller's software (for instance, STEP7, see the “5.1 STEP7 configuration“
section on page 33).
However sometimes it is necessary to set some bits and bytes according to the
working specifications you want to set.
Data transmission is carried out in compliance with the values set for the
encoder profile and shown in the following tables.
