6.5.4 FB 432 MC_ExternalEncoder - External encoder
Purpose
• The "MC_ExternalEncoder" technology function controls an external encoder
that can is used, for example, as physical leading axis (master) for
synchronous operation.
• The external encoder can be enabled / disabled.
• Absolute value encoder adjustment is possible
• Synchronization: The actual position value of an incremental encoder can be
set or influenced with the passive homing function.
Applicable to
• External encoders
Requirements
• The actual position value of an external encoder can only be influenced when
the encoder is enabled.
Overriding commands
An MC_ExternalEncoder command can only be canceled by a further
MC_ExternalEncoder command to the same technology object. An
MC_ExternalEncoder command does not cancel any other commands.
