Overview Description
The module BMX EAE 0300 is a synchronous serial interface designed for use with an absolute encoder, it is controlled by the user applications through an open SSI interface.
The position values of the SSI channel are automatically read by the module every fixed period, unless the channel is disabled.
Available Functions
The following table presents the main functionalities of the BMX EAE 0300 module:
Function
Description
Modulo
The modulo function limits the dynamics of the position value within the power of 2. An event (if enabled) detects the modulo passing. The reflex output can also be asserted at the passing of modulo (if configured).
Reduction
This function reduces the intrinsic resolution of the encoder by a value defined by the "reduction" parameter. This reduction is carried out by a shift in the bit field provided by the encoder.
Offset
The correction function of the encoder offset systematically corrects the offset produced by the encoder at mechanical position "0". The user enters the absolute encoder offset parameter.
Capture
The two capture input registers (per channel) enable the PLC program to carry out a dynamic measurement function between two points. The capture action can be triggered by two capture inputs. The event will be triggered at each occurrence of Capture.
Compare
Two independent comparators (per channel), with thresholds that can be modified by adjustment (explicit exchange), are able to generate an event or reflex output when the threshold is crossed.
