6.4 DDLM_Set_Prm
When 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 section “5.1 STEP7 configuration“).
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 values set for the encoder
profile and shown in the following tables.
