7.3.11 Pulse counting
To count pulses you will need the ML60B or ML460 amplifier. This amplifier
is able to process a maximum pulse string frequency of 1 MHz. Further in
formation about possible settings of this amplifier can be found in
è section
7.3.4 "Torque transducer", page 158.
Incremental transmitters (used for example to measure angles) return two
square wave signals which are phase-shifted by 90. The duty ratio between
the High and Low of the two signals must be about 1:1.
The settings are explained with the following example:
An angle of rotation transmitter returns two signals, each with 180 pulses/
revolution. They will be realized in the display as 360. Due to the pulse
number per revolution, a value of 1 is specified as the step, since a higher
revolution is not practical. The level of the square wave signal is 10 V.
In addition to the measured value, a frequency signal with four times the
count pulses is required at the output.
