Getting Started - first steps for operating this module

2.1

General information about the module

The XNE-2CNT-2PWM provides 2 counter channels (CNT1 and CNT 2) with 3 count inputs
each DI0 (A), DI1 (B) and DI2 (Z) as well as 2 channels with 2 outputs each, P0 and P1
(frequency output) and D1 and D2 (direction).
2.1.1

Counter inputs

The module's counter inputs allow the connection of encoders as well as of count- and direc-
tion signals, with the direction evaluation being optional.
Operation modes
• Counting
– Pulse and direction, → see page 43
– AB mode, → see page 44
• Measurement
– Frequency measurement / rotational speed measurement, → see page 53
– Period duration measurement, → see page 55
2.1.2

PWM outputs

Each channel provides two PWM outputs P1/D1 and P2/D2.
P1 and P2 are used for frequency output.
The logical status of the outputs D1 and D2 can be used to define the rotation direction. The
outputs can also be used independently of the PWM.
The outputs Px serve to give out a square wave signal with a defined mark-to-space ratio, a
defined period duration and a defined number of pulses.
operation modes
• Period duration / duty cycle, → see page 61
• High time / low time definition, → see page 63
