Product Description:

Input currents that exceed the measuring range cause the overflow numerical value of +32767. If the measured value is below the range, the underflow numerical value of -32767 is set.The input impedance is ca. 330 Ω. The current input has a self-protecting mechanism. If the input current gets too high, the shunt is switched off and the value for range overflow is generated. About every second, the unit tries
to switch on the shunt again. In this way the correct measurement will succeed after the current has reached a normal value again.The trigger of the self-protecting mechanism is displayed by the red LED Ovl as long as the overload is present. In the PLC system an error message is then stored

Product's Character:

The desired operating mode is set in a system constant (see documentation part "System technology"). The configured operating mode is only activated during initialization (power-on, cold start, warm start). For all operating modes, the same function block COUNTW is used (see programming software).
Independent of the selected operating mode, the following features are valid:The pulses at the counter input or the evaluated signals at tracks A and B in case of connection of incremental position sensors are counted.The maximum counting frequency is 50 kHz.The counter uses the terminals 2 (E 62,00) and 3
(E 62,01) as fast inputs and, in one operating mode,also the output terminal 46 (A 62,00). In order to make all binary inputs and outputs available for other purposes than counting, it is possible, to disable the
07 KT 98’s counting function.
