Absolute Rotary Pulse Encoder Gel 15xF

General Information

Function

The Lenord & Bauer Rotary Pulse Encoder GEL 15XF series has been developed with the intention of enabling the user to change plant-specific parameters. The absolute encoder can be programmed by means of a PC via the encoder programming line. The selected parameters stored in an E2PROM in the absolute encoder are protected against power failures. The programming software BB 150 (3 1/2" diskette, 1.4 MB) for menu-guided programming runs on any IBM-compatible PC-AT with a main memory of 512 KB and DOS 3.1or higher. The RS 485 interface signals are converted to the PCcompatible RS 232 interface in the converter cable.

The Set Reference mode permits setting of reference points 1 or 2. The reference values can be programmed by the user within the total number of steps.

In the Up-Down Mode, the output value of the absolute encoder can be increased or reduced by the user via the function inputs. The output change speed increases with the duration of signal application. Applying a logic 0 for a short time reset the output change speed. The set value is stored after about 6 seconds before the absolute encoder switches over to the normal coding mode. These functions can be used for electronic setting such as for changing the zero setpoint.

Input/Output circuits - Synchronous Serial Interface (SSI)

Input E6 Circuit for Absolute Encoder

Output Circuit for G,B,R for Abolsule Encoder

Synchronous Serial Interface (SSI)

Advantages:
  • lower costs and and reduced work due to minimized wiring
  • increased data safety due to repeat transmissions
  • maximum noise immunity due to symmetrical and synchronous data signals


The parallel data word generated by the encoder is converted into a serial data word and transmitted synchronously with the clock signal to the receiver electronics.
