Encoder support
The following optional interface modules are available:
• TTL encoder interface FEN-01: two TTL inputs
• HTL encoder interface FEN-31: HTL encoder input
The interface module is to be installed onto slot 1 on the drive control unit.
Load and motor feedback
Three different sources can be used as speed and position feedback: encoder 1,
motor position estimate. Any of these can be used for load position calculation or
motor control. The load position calculation makes it possible, for example, to
determine the position of a conveyor belt or the height of the load on a crane. The
feedback sources are selected by parameters
