General information Function The 5XF series has been developed with the intention of enabling the user to change plant-specific parameters. The encoder can be programmed by means of a PC via the encoder programming line. The selected parameters stored in an E 2 PROM in the absolute encoder are protected against power failures. The programming software BB 50 (3 /2" diskette,.4 MB) for menu-guided programming runs on any IBM-compatible PC-AT with a main memory of 52 KB and DOS 3. or higher. The RS 485 interface signals are converted to the PCcompatible RS 232 interface in the converter cable. Programmable parameters Resolution 0.0002 to 4096.0000 steps/360 Measuring range,2,4... 4,096 revolutions Output code Gray, Gray-Tanne, BCD, Binary or Binary-Tanne Code direction CW or CCW Logic polarity positive or negative (only with parallel interface) Parity bit ODD or EVEN Setmodes Set Reference or Up-Down mode Reference value 0 to total number of steps Reference value 2 0 to total number of steps Offset value - 32,768... + 32,768 Length of register 3, 6, 25 or 32 Bit (only with SSI interface) Monostable time... 682 µs (only with SSI interface) Identification number 0... 65,535 (ID number) Setmodes The functions Set Reference or Up-Down Mode can be programmed via inputs FE and FE2. FE FE0 Setmode Set Reference 0 0 normal coding mode 0 set reference point 0 set reference point 2 output value stored (latch) The Set Reference mode permits setting of reference points 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.
