II - 6 Switching Inputs and Outputs Reset actual value display to zero You can reset the actual value display of each axis to zero. Minimum pulse duration for zero reset: tmin ³ 100 ms Zero reset signal: make contact against 0 V or input pulse over TTL logic device (such as SN 74 LS XX): U H ³ 3.9 V (U MAX = 15 V) U L £ 0.9 V with I L £ 6 mA Using the switching signals If you wish to use the switching signals, you must supply POSITIP with 24 V d.c. at the D-sub connection EXT (pins 23 to 25; 0 V to pin 10). Pins 14 to 21 will then be supplied with 24 V as long as the display value is not within a switching range. These pins are then assigned to the axes with operating parameter P60.x. As soon as a display value is within the switching range, the voltage to the corresponding pin will be cut off. Define the switching range in operating parameter P61.x symmetrically about zero. If the location of the datum point changes, move the switching ranges correspondingly. Axis assignment: P60.x No axis assigned (Off): P60.x = 0 Assigned to axis 1: P60.x = 1 Assigned to axis 2: P60.x = 2 Assigned to axis 3: P60.x = 3 Assigned to axis 4: P60.x = 4 Define switching range: P 61.x 0 to 99 999.999 [mm] symmetrically about zero P61.x Permissible load at switching outputs IMAX = 100 mA Ohmic resistance Danger to internal components! Connect inductive loads only with a quenching diode parallel to the inductance. Accuracy of switching ranges and switching delay: P 69 You can select the switching delay and the accuracy with which the switching outputs are switched. You can choose between • Accuracy = display step; switching delay = 80 ms -> Mode 1:P 69 = 0 Grating period GP of encoder • Accuracy = 128 Switching delay = 5 ms -> Mode 2:P 69 = 1 – + X: P61.2 0 P61.2 P60.2 Fig. 50: The switching ranges are symmetrical about zero 108 Technical Information POSITIP 855
II - 6 Switching Inputs and Outputs Output "POSITIP ready for operation" In order to work with the signal "POSITIP is ready for operation" you must supply 24 V= to pins 23, 24 and 25 (0 V to pin 10). During normal operation, pin 11 of D-sub connection EXT has 24 V. If an error occurs which impairs the functioning of POSITIP (such as a hardware or checksum error), POSITIP switches the output at pin 11 to high impedance. POSITIP 855 Technical Information 109
