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 (DDLM_Set_Prm 
mode). 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 
Configuring the encoder via Siemens STEP7“ on page 14). 
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 according to the specifications of the 
encoder profile, as shown in the following tables.
