Application mode 2: A/B without N
The F-TM Count module supports the following application mode:
• A, B differential encoder signals
The figure below is an example of the A/B without N application mode:
Note
The encoder may also be powered from an external source. If an external source is used, only
the M supply voltage "To Encoder" must be connected to the encoder's ground/external
power source ground.
WARNING
An external source of power for the encoder must be at the same ground potential as
the power source for the F-TM Count module.
Ensure that ground potential for the external power source for the encoder and the F-TM
Count module power source are the same. Any potential differences in the two power
sources will cause current to flow through the modules that can cause damage to F-TM
Count module, power supplies and the encoder.
