Directional frequency inputs
Connecting sensors to the directional frequency inputs
Directional frequency inputs can operate in 2 modes.
Speed
which is frequency and
position
which is a pulse count. For the frequency ranges and trigger levels, see
Appendix A.
Simple directional frequency sensor
The positive terminal of the directional frequency sensor is connected to the +VREF
and the negative terminal to the -VREF respectively. The sensor signals are connected
to the DFIN+ and DFIN- positions..
N
OTICE
The negative terminal of the sensor must not be connected to the chassis.
Maximum load for VREF position, see Appendix A.
EXAMPLE
Connect the positive and negative terminals of the frequency sensor to +VREF and
-VREF, respectively. Then connect the sensor signals to DFIN+ and DFIN-.
