Pulse Output. ADLINK Technology PCI-8136M

4.5 Pulse Output

The PCI-8136M provides 6 pulse output channels. They are used to send out constant-frequency pulse trains. When changing the output frequency of any channel, there is at most 265ms time delay.

There are also 3 kinds of pulse output: (1). plus and minus pulses input(CW/CCW mode); (2) pulse and direction input(Pulse/DIR); (3). 90° phase difference signals(AB phase mode); pulse and direction output (Pulse/DIR)

In this mode, the high/low status of DIR defines the plus/negative direction, whereas OUT generates the pulse train.

Plus and Minus Pulses Output Mode(CW/CCW Mode)

In this mode, plus frequency (plus direction) goes on OUT, whereas negative frequency (negative direction) is generated from DIR.

90° phase difference signals Output Mode(AB phase Mode)

In this mode, the OUT signal is 90° phase leading or lagging in comparison with DIR signal. Where “lead” or “lag' of phase difference between two signals is caused by the direction of pulse train.
