Detector compatibility
2 wire/3 wire (24 V) with the following specifications:
b waste voltage at state 1y7 V
b switched current y 2.5 mA
b residual current u1.5 mA
(1) Using an absolute encoder with parallel outputs requires the Telefast 2 ABE 7CPA 11 adaptation base. This base is used to multiplex up to 4 absolute encoders.
This multiplexing is controlled by the TSX Micro PLC discrete outputs.
Functions
Module type TSX CTZ 1B
Read frequency
Depending on mode:
200 kHz in slow mode
1 MHz in fast mode
Comparative function
4 thresholds each linked to 1 maskable EVti event (activation upon event tasks) and to
1 position bit in relation to the (upper/lower) threshold
Capture/measure function
2 capture inputs and 2 capture registers (on rising or falling edge)
Modulo function
The number of encoder data bits can be configured, with:
b The modulo function limits the dynamic of the position value to a number of points defined
by the "modulo" parameter value. The "modulo" passage causes an EVti activation event
for the event task
b The reduction function is used to reduce the position value supplied by the absolute encoder
Offset function
Two offset functions for the position measure are available:
b Correction function for the encoder offset on the "zero" mechanical position
b Position measure adjustment function: corresponds to the position value adjustment
(more or less)
Checks
The checks are of the following type:
b Detecting the encoder feedback voltage
b Checking the encoder link
b Parity check
