Absolute encoders - parallel Hollow shaft ø14 mm Singleturn encoder 13 bit, 1024 cams RXA1H Terminal significance Terminal assignment UB Encoder voltage supply. Connector Core colour Assignment GND Ground connection of encoder and output drivers relating to UB. Pin 1 white Output 1 Pin 2 brown Output 2 Zero setting Input for setting a zero point anywhere within the programmed encoder resolution. The zero setting operation is released by a High impulse and has to be in line with the selected counting direction (UP/DOWN). Connect to GND after reset operation for maximum interference immunity. Impulse duration >100 ms. For safety reasons any reset operation will immediately stop a running cams program. Start Programs Program start input. Applying a High potential (UB) for at least 100 ms will start the selected cams program. If the start input is firmly connected to UB, the cams program selected at the programming inputs will immediately start after encoder power on. Inputs for program selection 1-16. Preset of the cams program in binary code. Program 1 is selected by code 0-0-0-0 program 16 by 1-1-1-1. Input „Program 1“: Valence „1“ Input „Program 2“: Valence „2“ Input „Program 4“: Valence „4“ Input „Program 8“: Valence „8“ After encoder power on and upon every alteration at the programming inputs the cams program selection by the four programming inputs will be valid. A later selection by serial programming interface will overwrite the selection made at the four programming inputs. Every alteration of the program inputs will immediately stop a running cams program. VPOS1 VPOS2 Separate voltage supply of output driver (outputs 1-8: pin 32, outputs 9-16: pin 33).
