Preset start values
You can preset both positive and negative start values
for the counter.
The counting operation starts at the start value and is
continued in correspondence with the arrows in the
diagram until the enabling is stopped or a start value is
loaded again.
Negative start value
The minimum negative start value is
–32768 (8000H).
By presetting a negative start value it is thus possible
to count a maximum of 32768 pulses up to the zero
crossing of the counter.
Positive start value
If a positive start value is preset, the counter counts up
to the value of +32767 (7FFFH), continues the
counting operation at the value of–32768 (8000H) and
then signals the zero crossing when reaching the
transition from –1 to 0.
The minimum positive start value is 1. If you preset this
value, 65535 pulses will be counted up to the zero
crossing.
In order to count more than 32767 pulses up to the
zero crossing, the start value has to be calculated
according to the following equation:
Start value = 32767 – (number of pulses – 32768)
Example:
40 000 pulses are to be counted.
The start value is in the positive range, because more
than 32768 pulses have to be counted.Technical data 07 KT 93

Potential differences In order to avoid potential differences between the
07 KT 93 central unit and the peripheral device connected to the COM1 interface, this device is supplied
from the switch cabinet socket (see also the earthing
connections in Fig. 3–3).
