3.8.2 Parameterization
Parameterization means providing a PROFIBUS-DP slave with certain information
required for operating purposes before it begins the cyclical exchange of process
data. For example, the encoder requires data concerning the resolution, count
direction, preset values, etc.
The configuration program for the PROFIBUS-DP master usually provides an input
mask via which the user can enter the parameter data or select from lists. The
structure of the input mask is stored in the device master file. The number and type of
the parameters to be entered by the user depend on the chosen nominal
configuration.
3.8.2.1 Code sequence:
Defines the count direction of the encoder.
Selection
• Increasing clockwise *
• Increasing counter-clockwise
3.8.2.2 Class 2 functionality:
Defines the encoder's range of functions.
"Class 2 deactivated" means that the encoder only performs Class 1 functions, does
not scale the position value and is not adjustable.
Selection
• No (Class 2 functions deactivated)*
• Yes (Class 2 activated)
3.8.2.3 Commissioning diagnostic control:
Defines whether the encoder outputs an extended diagnostic message.
Selection
• Disabled (Commissioning diagnostic control deactivated)*
• Enabled (Commissioning diagnostic control activated)
3.8.2.4 Scaling function control:
Defines whether the encoder scales the position on the basis of the subsequent
parameter. If Class 2 is deactivated, it does not scale the position value and is not
adjustable.
Selection
• Disabled (scaling deactivated)*
• Enabled (scaling activated)
3.8.2.5 Measuring units per revolution:
Defines the number of increments displayed by the encoder for each revolution of the
encoder shaft.
Input
• Lower limit: 1 increment / revolution
• Upper limit: 8192 increments per revolution (depending on capacity -
marked on rating plate)
• Default value: 4096
